nyone who has ever considered Peak Performance biased
towards endurance sports and events can bask happily in the
Aalmost entirely explosive emphasis of this special report. It will
not help you to work out/run/swim/cycle for longer (although there are
other reports in the series that do just that) but it will give you the
knowledge and the tools you need to enhance your speed, increase your
power and boost your strength.
Prepared for you by PP s expert conditioning duo, John Shepherd and
Raphael Brandon, the report covers a wide range of interests, from
strength training for swimmers (gym exercises designed to replicate
water action as closely as possible) to rotational power training (very
useful for all sports involving sudden turns); from speed development
(drills to help you run like the wind) to battling the ageing process (sadly
speed declines much faster than endurance with the passing years); and
from weight training (impossible for any athlete to ignore these days) to
agility training (much more than optimum sports technique).
In all these articles you will find not just a distillation and critique of
the latest scientific research but a variety of carefully selected, highly-
targeted practical drills, techniques and exercises which will help you to
enhance your own abilities, whatever your chosen sport or activity. You
will not just want to read it once but keep it by your side to refer to again
and again, and use it to track your inevitable progress.
Have a great time reading  and living  this special report.

STRENGTH TRAINING
Fish out of water: the
land-lubbers strength
programme for swim
competition
To optimise strength and power, competitive swimmers need to
supplement their pool training with land training in the gym.
For best effect, swimmers need to follow a programme of
exercises that replicate their actions in the water as closely as
possible.
Strength and conditioning experts around the world all
agree that, for time spent in the gym to have a positive impact
on your sports performance, you must ensure the exercises you
perform  and the way you perform them  are related to your
sporting movements in competition. For example, Barbell
Squats involve ankle, knee and hip extensions in a vertical
plane that are directly related to the mechanics of a vertical
jump; thus the squat is a useful exercise for developing jump
performance.
If we perform a basic analysis of the mechanics of the front
crawl stroke, the main actions that produce forward propulsion
through the water are:
1 the  arm pull down through the water, which propels the
swimmer forward and
1 the  leg kick , which alternates hip flexion and extension
of the legs.
In addition, competitive swimming involves:
1 the  dive start and push off turn , which involves dynamic
ankle, knee and hip extension.
PAGE 11
PEAK PERFORMANCE STRENGTH TRAINING SPECIAL REPORT
When designing your strength programme, you should focus
mainly on exercises related to these movements. Other
exercises may use the same muscles as those involved in
swimming, but only exercises that use right muscles in a related
mechanical movement will provide optimum training benefit.
A limitation of land training with weights for swimming is
that the type of resistance you encounter when moving in the
water is different from the resistance occurring when you
move a weight through the air. In the water, the faster you pull
or kick the greater the resistance applied back by the water; on
land, a given weight requires a constant force to move it,
regardless of the speed of movement.
Hydraulic-type resistance equipment that mimics aquatic
resistance is expensive and not widely available. The best
compromise when using regular equipment is to try to mimic
the speed and nature of the swimming stroke. To this end, you
should aim to perform the strength exercises with a smooth
and constant force, and select weights that allow the movement
to be performed at a swimming-related speed. For example,
the leg-kicking motion during front crawl is quite fast, so hip
flexion and extension exercises that can be performed at a
good speed would be best.
The following exercises are related to the mechanics of
the front crawl stroke. For each component, the relevant
exercises are described and their mechanical relationship to
the stroke explained.
Arm pull down exercises
1. Cable rotational front and back pulls
Front pull This is the mechanical equivalent to the pulling-
through-the-water action in front crawl, as the hand comes
diagonally across the body as it pulls down. For this exercise
you need a high pulley machine with a simple handle grip.
Kneel down on one knee to the side of the machine. Take
the hand nearest the pulley and grasp the handle with the hand
high and slightly out to your side. Before you start the exercise
make sure your back is straight, your shoulders are wide and
PAGE 12
 PEAK PERFORMANCE STRENGTH TRAINING SPECIAL REPORT
your chin is tucked in. Pull the handle down and lower your
arm across your body in a rotational movement until your hand
is next to the opposite hip. Smoothly return the bar to the start
position and continue, performing sets of 5-8 reps for
maximum strength or 12-15 for strength endurance.
Try to keep your posture solid throughout the movement.
Maintain a slight bend in the elbow as you pull, but focus your
effort on the shoulder muscles only.
Rear pull This exercise involves the opposite movement to the
front pull and is useful for promoting a balanced strength

the inside hip and fix a slight bend in the elbow. Pull the handle

up and away from your body, rotating the arm up and out.
Finish with the handle high and out to the side, with the palm of
the hand facing forwards. Smoothly return the handle back and
across to the opposite hip, and continue. Again go for sets of 5-8
reps for maximum strength or 12-15 for strength endurance.
Keeping your posture solid during this exercise is quite
difficult, as it is tempting to use your trunk muscles to help the
rotation movement. However, you can train your core stability
skills by keeping your navel pulled into your spine and relaxing
your upper body so there are no additional movements apart
from the arm raise and rotation.
In combination, the front and rear diagonal pull train
almost every muscle in the shoulder joint and shoulder girdle.
This makes them very useful exercises for any sport.

the pull.
Lie on your back on the floor, with knees bent slightly so
your lower back is comfortable. Grasp the ball in one hand
with your arm up and behind your head, slightly bent at the
elbow. Vigorously pull the arm up and down across your body,
throwing the ball over the opposite knee. Get your partner to
return the ball, and perform sets of 8-12 repetitions with each
arm in turn.
Do not lift your head or pull up from the stomach as you
throw. Focus on producing the power from the shoulder and
pulling across the body as you do in front crawl.
3. Swiss ball body pulls
This is a  closed kinetic chain movement, where the moving
limbs remain in contact with a fixed object  in this case the
hands with the floor. Such movements are thought to be
particularly functional for sports performance, so offering
greater training benefits.
This exercise is performed in a horizontal prone position,
with the arms pulling down under the body, matching the
position and action of a swimmer in the pool.
Position yourself face down, with your lower legs on the
Swiss ball and your hands on the floor supporting your weight,
body parallel to the floor. This is the equivalent of a press-up
position with your feet up. Slowly roll the ball up your legs
while your arms extend out in front of you until you achieve a
PAGE 14
 PEAK PERFORMANCE STRENGTH TRAINING SPECIAL REPORT
stretched position, with a straight line through your arms,
shoulders, back, hips and legs. At this point your body will
make a shallow angle with the floor and the ball will be
positioned on your thighs. Then, keeping this perfect
alignment of your body, push down through your hands into
the floor and pull yourself back to the press-up position. The
ball should roll back down your legs as you do this. Perform
sets of 8-12 repetitions.
The difficult part of the exercise is the pull back up. At this
point you must use your stomach muscles to support your
spine and focus on using a strong pull of the shoulder muscles
to raise your body back to the parallel position. This exercise is
not easy, but it is very beneficial for many sports, helping to
develop core and shoulder strength.
Leg kick exercises
Hip extension and flexion kick
These exercises mimic the upward and downward phases of
the swimmer s kick action, where the glutes and hamstrings
extend and the hip flexors flex the leg at the hip. For these
exercises you need a low pulley machine with an ankle strap
attachment. Each leg is worked independently to increase the
specificity for swimming, and the weights used should be
relatively light so you can kick with good speed, as in the pool.
Hip extension Stand facing the low pulley machine, with the
ankle strap attached to one leg. Lift this leg off the floor, taking
up the slack of the cable, and place your balance solidly on the
other leg. Hold onto the machine s frame with your hands to
stabilise your upper body and check that your back is straight,
with shoulders relaxed.
Pull the cable back dynamically by extending the leg
backwards until you feel you need to lean forwards, then bring
it back in a controlled manner to the start position, retaining
good posture. Continue pulling the leg back, focusing on the
gluteals and hamstrings to kick back powerfully.
PAGE 15
PEAK PERFORMANCE STRENGTH TRAINING SPECIAL REPORT
Hip flexion Stand with your back to the low pulley machine,
with the ankle strap attached to one leg. Lift this leg off the
floor, taking up the slack of the cable, and place your balance
solidly on the other leg. Use a stick to support yourself, and
check that your back is straight with your shoulders relaxed.
Pull the cable dynamically by kicking the leg forwards. Pull the
weight, using your hip flexor muscles at the top and front of the
thigh, until your leg reaches an angle of about 30� or you start
to lean back. Smoothly return your leg to the start position,
retaining good posture, and continue.
Perform sets of 10 reps at a fast speed and build up to sets of
20 or 30 for power endurance of this movement.
 Dive start and push-off turn exercise
Barbell squat jumps
This exercise involves dynamic extension of the ankle, knee
and hip joints and trains the calf, quadriceps and gluteal
muscles to improve vertical jump performance. The vertical
jump is mechanically related to the dive start and push-off
turns involved in swimming: with the dive or turn, the ankle,
knee and hip extension propels you forwards in the horizontal
plane, while with the jump the leg extension propels you
upwards in the vertical plane. Essentially, it s the same
movement rotated by 90�!
The point of using a barbell to add weight to the squat is to
help you to generate peak power. If you perform the jump
squat with body weight only, the jump will be very fast and
high. With the addition of a moderate weight (about 30-40%
of the 1 repetition max weight for the squat exercise), the jump
will not be as high or fast, but the muscular power required to
leave the ground will be maximal. This is based on the
knowledge that peak power is achieved when the force used is
about one third of the maximum force for that movement.
Again, your goal is to attempt to achieve the fastest
extension of the legs to maximise power production and
training benefit. If you use 30-40% of 1RM weight, I
recommend 3-5 sets of 5 repetitions.
PAGE 16
 PEAK PERFORMANCE STRENGTH TRAINING SPECIAL REPORT
Stand with the barbell across the back of your shoulders.
Squat down, bending at the hips and knee, making sure the
weight goes down through the back half of your foot. When
you reach the half squat position, drive up dynamically, rapidly
extending your legs so that you leave the floor briefly. Absorb
the landing with soft knees, then go smoothly into the squat
again. Continue for 5 repetitions.
The bottom line
In summary:
Strength and power training is essential for �lite swimming
performance.
To optimise the benefit of land-based training, you must
select exercises with mechanical relevance to the swimming
action, particularly those movements which propel the
swimmer through the water, such as the arm pull and leg kick.
As the resistance in the water is different from the resistance
provided by weight equipment on land, unless you have special
hydraulic equipment you must also focus on mimicking the
speed and smooth movement of the swimming stroke when
performing land-based exercises.
Various exercises for the arm pull, leg kick, dive and turn
movements are suggested, all with a good functional
relationship to the swimming action. While this is not a
definitive or exhaustive selection of exercises, especially as it
focuses solely on front crawl, it involves highly specific
swimming movements in terms of mechanics, positions and
speed. When you design strength programmes for swimming
performance or any other sport, be sure to think about each
exercise in terms of its relevance to performance.

POWER TRAINING
Add power to your punch
with plyometric exercise
Do you ever look in awe at top sprinters when you realise just
how fast they are running? Dwain Chambers would get a
speeding ticket in built-up areas! And what about the slam-
dunk in basketball? How on earth do players like Kobe Bryant
leave planet earth and attain such height? And what of
Matthew Pinsent and James Cracknell? Unbridled, these
rowers would seem to be able to tear their boat apart!
Wherever you look in the world of top-class sport, power
counts; and one of the best ways of developing this most
precious commodity is through plyometric training.
Plyometric exercises are based on the understanding that a
concentric (shortening) muscular contraction is much stronger
if it immediately follows an eccentric (lengthening) contraction
of the same muscle. It s a bit like stretching out a coiled spring
to its fullest extent and then letting it go: immense levels of
energy are released in a split second as the spring recoils.
Plyometric exercises develop this recoil or, more technically,
the stretch/reflex capacity in a muscle. With regular exposure
to this training stimulus, muscle fibre should be able to store
more elastic energy and transfer more quickly and powerfully
from the eccentric to the concentric phase.
Unlike traditional weight training, plyometric drills can
closely mimic both the movement pattern and the speed of
execution of actual sports performance. While a sprinter s
foot may be in contact with the ground for just 0.084 seconds,
and even running at a moderate pace can result in a foot
strike time of 0.2 seconds, most standard weight-training
lifts, performed at their quickest, take 0.5-0.7 seconds to
complete. A plyometric drill will match runners ground
PAGE 19
PEAK PERFORMANCE STRENGTH TRAINING SPECIAL REPORT
contact times, while at the same time generating a significant
amount of force.
One piece of Soviet research showed that under, certain
conditions, athletes could display brief (in the range of 0.037-
0.067 seconds) plyometrically-induced muscular tensions
equivalent to 1,500-3,500kg, although it should be noted that
this example was probably based on eccentric exercises (drop
and hold depth jumps from a great height) rather than the
more familiar types of plyometric drills, of which more later.
So you can see why weight training for sport can be limiting
when it comes to specific training transference, and why
plyometrics are a great way to address power needs.
To get the best out of plyometrics you need adequate pre-
conditioning. Some authorities recommend that an athlete
should be able to half squat at least 1.5 times their body weight
before embarking on a plyometric programme, but this may be an
excessive requirement, particularly if an athlete is planning to
embark on a progressive plyometric-conditioning programme,
beginning with low-intensity drills before progressing to the more
intense exercises (see table opposite). As with all  new training
experiences, progress should be incremental.

training, it should not be discounted as means of generating

plyometrics for a heightened fast twitch muscle fibre response
(see PP114 Feb 1999).
When it comes to selecting the right plyometric moves, the
coach or athlete needs to consider the specifics of their sport,
the athlete s maturity, his level of pre-conditioning and his
ability to pick up what can be a complex skill. Single leg moves
are often more complex and stressful than double leg moves.

1 Drop and hold from height above 1m Very high
Compare squat jumps to alternate leg bounding over 20m,
with either a single or double arm shift and a 15m run-on. The
complexity and speed component of the latter is significantly
greater than the former. And it is likely that a beginner  or
even a moderately conditioned individual  would not be able
to perform even the first bound without collapsing, let alone a
series over 20m, whereas he or she would probably be able to
perform five consecutive squat jumps.
Always err on the side of caution when selecting your
moves. The table above ranks various plyometric lower limb
drills in order of intensity. Those new to this type of training
should be sure to start with the low-intensity moves when
introducing plyometrics into their training programme. You
should wear well-cushioned trainers and perform the drills on
a yielding surface, such as a running track or sprung floor.
Eccentric drop and hold jumps
These drills, although utilised in training and research from the
1960s onwards, have not been as prevalent in training programmes
as the other drills referred to in the table. Eccentric drills focus on
PAGE 21
PEAK PERFORMANCE STRENGTH TRAINING SPECIAL REPORT
the plant and absorption phase of a dynamic movement and
forsake the concentric phase in the stretch/reflex sequence. They
are advocated because of their huge force absorption potential,
and as a further conditioner of the stretch/reflex.
Poor interpretation of the work done by Yuri Verhoshansky
(the former Soviet sports scientist, known as the  father of
plyometric research) sometimes resulted in subjects being
asked to perform depth jumps (ie rebound on landing) from
very considerable heights (eg in excess of 3m) with obvious
potential for injury. (I myself was once asked to perform this
form of eccentric training from a similar height but refused on
the grounds of sanity. The height itself is a major fear factor, let
alone the landing!)
However, if implemented sensibly and from lower heights,
or in the form of  bound/hop and hold drills, eccentric power
training can be an effective way of further developing power.
It s yet another way to overload muscles and thus avoid
stagnation and maintain training progression in seasoned
athletes. Both coach and athlete need to be aware that
eccentric training is likely to cause muscular soreness even in
the well-conditioned; but, as with other forms of eccentric
training, such as downhill running, one session may be all that
is needed to  inoculate the body against further soreness.
As with weight or endurance training, you can periodise
your plyometric training. Obviously the specific requirements
of your sport and your competitive aims for the forthcoming
season need to be considered, but there are some general
guidelines for progression. The following recommendations
are based on the requirements of a power athlete with a single
main competition period, but occasional reference is made to
the needs of endurance athletes.
Pre-season/early conditioning phase
Plyometric moves such as split squats, jump squats and straight
leg jumps can all be incorporated into a circuit. Normal circuit
training protocols should be used  ie high reps, short
recoveries. At this stage of general conditioning they will
PAGE 22
 PEAK PERFORMANCE STRENGTH TRAINING SPECIAL REPORT
develop low-level power and general sport specific movement
pattern conditioning, as well as specific endurance. If you are
an endurance athlete you could continue this type of training
beyond your pre-condition phase and integrate it into your
non-track/rowing/cycling sessions. Runners could also
incorporate plyometric drills into fartlek-type workouts.
Main power conditioning phase
Athletes who are sufficiently skilled should use drills from the
medium-intensity categories in the table during this phase of
training. Runners should progress to single leg variants, as
these will have the greatest relevance to their sport. Do not
neglect lower leg drills such as straight leg jumps  where the
athlete literally  pogoes up and down on the spot. These will
improve specific calf and achilles tendon power, leading to
optimum foot-strike and force return when running.

expression

Competition phase
In power sports the activity itself will act as the prime
conditioner: nothing beats a competitive situation for
optimum power expression. But in training athletes should
perform high-quality plyometric drills in low numbers, well
away (7-10 days) from important competitions. Endurance
athletes could continue with medium/high-quality drills as part
of their warm ups or low-intensity workouts.
PAGE 23
PEAK PERFORMANCE STRENGTH TRAINING SPECIAL REPORT
Volume and intensity guidelines
The recommended volume of specific jumps in any one session
will vary with intensity and progression goals. For jumps on the
spot or from standing, measure the volume in terms of foot
contacts. As a guide, a beginner in a single pre-season workout
could perform 60-100 foot contacts of low-intensity exercises.
The intermediate plyometrics exponent might be able to do
100-150 foot contacts of low-intensity exercises in one workout
and 100 of moderate-intensity exercises in another, while an
advanced exerciser might be capable of 150-200 foot contacts
of low-to-moderate intensity exercises in a single session.
Intensity is the key: the more dynamic the move and the
greater the power generated, the fewer foot contacts are
required. As training phases progress, maintaining quality is
crucial and the number of foot contacts should be reduced, as
optimum power and speed need to govern performance.
Bounding and hops are best measured in terms of sets and
reps, distance covered and whether they are performed from a
standing start or with a run-on. Verhoshansky recommended
incorporating a maximum of 5-10 bounds per set into a session,
with no more than 50-75 ground contacts. If a run-on is used,
the number of reps should be reduced.
For optimum sport specific training effect performers should
not allow themselves to become fatigued. Rest between sets
should be in the region of 1-2 minutes; successive depth jumps or
drop jumps should be separated by intervals of at least 15-30
seconds  or even longer if very intense multiple hops and jumps
routines are being performed. Such recovery intervals will allow
the stretch reflex mechanism to return to optimum capability.
In terms of number of sessions, 2-3 per week should suffice
 but they should not be performed on consecutive days or 7-10
days before important competitions. Those new to this form of
training may experience an initial decline in their performance
until they become accustomed to the training method.

WEIGHT TRAINING
For sporting success make
your weights programme
highly specific to your
chosen activity
These days, hardly any sports performers can afford to neglect
weight training. Get this training right and you could find your
place on the medal rostrum; get it wrong and you could end up
at the back of the field.
Weight training for endurance
It has long been accepted that weight training (and the right
strength training programme) can improve performance for
aerobic athletes. Take swimming: depending on the stroke,
the arms and legs contribute different amounts of power to
propel the swimmer through the water. Freestyle, for
example, requires an upper body contribution of 70% and a
lower body contribution of 30%. By strengthening the
muscles that move the shoulder girdle, upper arm and
forearm, hips and legs, it follows that, everything else being
equal, performance will be improved.
But it s crucial to select the right exercises, perform them at
the right intensity and place them within a progressive and
carefully structured weights programme. Olympic rowing
coach Terry O Neill believes that a weight training programme
for his sport should mirror actual race requirements as closely
as possible (a principle that should always be adhered to
regardless of sport). This means that:
1. The exercises selected must be relevant to rowing;
2. They must be performed ultimately at a pace equivalent
to the actual stroke;
PAGE 27
PEAK PERFORMANCE STRENGTH TRAINING SPECIAL REPORT
3. They must create conditions that mirror the heart rate
levels sustained during a 2k race and
4. They must reflect the time it takes to complete the race
distance.
In his most specific six-week weight training microcycle,
O Neill reduces the amount of weight the rowers attempt to
between 15 and 30kg. This is so that they can complete 45
seconds of continuous rhythmic exercise at a similar rate to
the stroke in a race.
At the end of each station, the athlete moves on to the next
exercise without stopping, providing a total of eight minutes of
work, during which time the heart rate will rise to 85-95% of
maximum (see table below for exercises).
O Neill gets the athletes to rest for two minutes at the end of
each circuit and the aim is for them to complete three of these

exercises utilised are: high pulls, press behind neck, front curl,
bent over rowing, lateral dips (side bends) to right and left,
squat, bench press, clean and press, jack knife crunch, bench
pull and hyper-extensions.

fibres and the cardiovascular system, an intense physiological
response would be elicited  similar to that achieved during a
high-intensity interval-style rowing workout.
This workout should also avoid the  physiological confusion
that can arise from targeting two different physiological goals
 eg strength and endurance  at the same time. (Note that it
was designed for indoor rowing but was adapted from O Neill s
vast knowledge of on-water rowing training.)
Weight training for speed/power: why bigger
is not always best
Lifting progressively heavier weights will not in itself lead to
improved power and speed, but many athletes and coaches still
get caught up with this  heavier and bigger is best strategy. Too
much bulk is just that: an additional load to transport around
the track or into the air. If increased muscle size on its own
brought the required results, then a body builder would be able
to run as fast as 100m world record holder Tim Montgomery.
It s how you develop the size and strength, and where you
take it to after and during a gross strength development phase,
that counts. A larger (and stronger) muscle will exert greater
force and ultimately more power, but simply pushing out near
maximum rep lifts, rep after rep, without sport specific
channelling is a waste of time. So how should you weight train
for explosive power?
Charles Van Commenee is UK Athletics multi-events and
jumps coach and it was he who coached Denise Lewis to
Sydney Gold. He believes that to develop power you initially
need a good strength base, and advocates the use of exercises
that train the whole body. Intensity is set at 90% of one rep
maximum (1RM) and his athletes perform 5-15 sets, but only
using 1-2 reps and interspersed by long recovery periods of
3-4 minutes.
After a couple of months training this way, the athletes
move on to a power development phase, lifting at 70-85% of
1RM. The number of sets performed depends on the stage of
the training year, but vary between three and six. At 70% of
PAGE 29
PEAK PERFORMANCE STRENGTH TRAINING SPECIAL REPORT
1RM, five reps are performed, and at 85%, three. As before, a
good recovery is crucial to unimpaired performance.
Van Commenee explains his training methodology in terms
of a specific hormonal response. At a high percentage of 1RM,
testosterone is released, boosting the speed development
which his athletes need; at lower percentages and using
multiple reps (8-10), growth hormone release tends to
predominate, which is good for general muscle building but
less advantageous for power athletes, for whom power-to-
weight ratio is crucial.
Again, as with our rowing weight training plan, it is vital to
select exercises that have a real relevance to the sport in
question, particularly during the power development phase.
The direct transference of, for example, a power clean to a
high jump take off is marginal  and much less direct than the
physiological responses elicited by our rowing schedule.
A power clean cannot be performed at the speed of a high
jump take off, nor could the same amount of force be
overcome and nor, of course, could it be performed on one leg
after a curved approach to a bar.
Weight training for speed (and endurance) obviously has
certain limitations. It can only take an athlete so far, and more
specialised exercises like plyometrics, sport specific drills and
the sport itself must be used to channel the strength gained
through weight training directly into improved performance.
Weight training and open sports skills
Swimming, rowing and sprinting are predominately  closed
skills , requiring the same movement pattern to be repeated
over and over again. However, football, rugby, tennis and
other field or court sports require myriad  open sports skills .
And it is in these sports that the direct contribution of weight
training to performance can appear less relevant. A tennis
player reacts to a serve, a goal-keeper to a shot  and weight
training is unlikely to condition a directly transferable
movement pattern. Why? Because speed of movement,
balance, proprioception and, of course, specific sport skill are
PAGE 30
 PEAK PERFORMANCE STRENGTH TRAINING SPECIAL REPORT
incredibly specific to the requirement of the movements.
So what is the role of weight training for these sports? The
answer is twofold:
1. To strengthen the body and protect it from injury by
strengthening tendons, ligaments and muscles (a further
reason for endurance athletes to weight train);
2. To provide a base for better (stronger/less fatigued/faster)
open skill performance.
Mike Antoniades, a specialist speed, power and weight
training coach, who has worked with many top sportsmen and
women using the Frappier Acceleration system (see article on
page 79), provides a third reason why the open skills performer
should not neglect weight training. He notes that footballers
can lose up to 35% of their strength during a season  and
more if they are unlucky enough to sustain an injury. The open
sports skill performer therefore needs a weight training
programme that maintains specific strength across a season.
Sport specific weight training exercises
The table below includes highly specific weight training
exercises. Some, like the first, even contain an element of
open sports skill performance because the performer has
not just to perform the move but also to balance and be
spatially aware. This is similar to the requirements of a
striker having to take a shot at goal while off-balance. Note
that these are advanced moves and should be attempted only
by well-conditioned athletes with a suitable level of prior-
conditioning.
Six top weight training tips for enhancing
performance
1. Do some  muscle re-education work after lifting. If you
are a cyclist, for example, you could do three minutes on
a spin cycle after weight training. You will have stressed
the muscles through weight training and the sport specific
task that follows will help to re-coordinate the firing
PAGE 31
PEAK PERFORMANCE STRENGTH TRAINING SPECIAL REPORT
patterns of your muscles. A runner or games player could
achieve the same by performing some light strides after a
weights workout.
2. Devise a progressive weight training programme to
accompany the demands of your sport, but never lose sight
of the sport itself. Weight training is largely peripheral
unless it is adequately channelled into performance.
3. Select exercises, particularly during key training phases,
that replicate the movement and have a similar speed
element to the sport in question.
4. Take your level of maturity as well as your sport into
account when devising your programme of weight training.
5. Don t turn into a gym narcissist, marvelling at your great
new physique: it could turn into a burdensome suit of
armour for you to haul around.
6. The more experienced the performer the more the coach
will have to work at exploring new avenues for enhancing
sports performance. Revisiting a weights programme
could be crucial: look closely at the transition to
competitive season phases and check out whether previous
strength gains really are improving sports performance.

POWER v STRENGTH TRAINING
Strength or power: which
matters most for peak
athletic performance?
Do you strength train for your chosen sport? And do you
believe it makes you faster as well as stronger? If so, you could
be barking up the wrong tree and might be better advised to
work on your power.
Let me explain why. The figure below represents the
theoretical relationship between concentric muscular force
and muscle contraction velocity, or speed. Maximum force is
generated by a maximal voluntary isometric contraction
(MVIC), which has zero velocity. In theoretical terms, strength
is defined as the maximum force of a certain movement. In
practice, it is defined by the 1 repetition maximum (RM) load
of an exercise in the gym.
The 1RM of a movement will produce slightly less force
than the MVIC, as the 1RM is dynamic rather than static. To
illustrate this by example, an athlete s maximum squat may be
200kg, this being the weight he can lift, just once, with a
maximum effort. At 201kg, the athlete would not be able to
move the bar; however, if he applied max effort the MVIC
force would be slightly greater than the force produced during
the successful 1RM lift. Nevertheless, for the purposes of most
coaches and athletes, it is fair to assume that 1RM is highly
correlated with maximum isometric force.
In many cases, the aim of a strength programme is simply to
increase maximum strength. Athletes typically train with
weights between 75% and 95% of 1RM, and after a few weeks
their 1RM scores go up, which is great because it means they
are stronger. Or is it so great? Look at the force-velocity curve
PAGE 35
PEAK PERFORMANCE STRENGTH TRAINING SPECIAL REPORT
again and note that at the high force end of the curve the
velocity of movement is at its slowest. Now think about how an
athlete lifts very heavy weights  slowly. This is because it takes
time  more than 400msec  to develop maximal force within
the muscle: it cannot be switched on like a light.
Most athletic movements do not involve slow contractions
at near maximum force, but are characterised by mid-to-high
velocity. For example, the contact time of the foot during
sprinting is about 100msec  not long enough to produce half
of maximum force. This leads you to think about the benefits
of strength training in relation to athletic performance a little
more critically. What, you might ask, is the point of being
stronger at slow speeds when most athletic movements involve
high velocities?
Power  how to generate rapid force
A separate quality, quite distinct from strength, which can be
developed with training, is power. In simple terms, power is the
ability to generate force quickly; it is defined mathematically
as force x velocity. If you look at the force-velocity curve once
again, you will see that high levels of power will occur in the
mid-range of either force or velocity. If an athlete develops
greater power, this, in turn, enhances his ability to generate
both force (strength) and velocity (speed). This amalgam of
speed and strength may be more useful for athletic
performance than strength alone.
The above explanations of the force-velocity curve and the
difference between strength and power raise two important
questions:
1. Would an athlete benefit more from developing maximum
strength or power?
2. What are the key differences between max strength training
and power training?
For athletes who are inexperienced in strength training, any
increase in maximum strength will tend to increase force
across the whole velocity range of the force-velocity curve
PAGE 36
 PEAK PERFORMANCE STRENGTH TRAINING SPECIAL REPORT
(1). This means that increases in maximum strength (greater
1RMs in the gym) will also lead to increases in power and the
ability to generate more force at fast speeds. Indeed, research
shows that maximum strength is strongly correlated with
power, especially in less experienced athletes (2). This
endorses traditional heavy weight training (75-95% of 1RM)
as a way to improve athletic performance.
But research also shows that max strength development
becomes limited beyond a certain point. Once an athlete has

slow muscle contractions.

By contrast, power or  ballistic training has been shown to
increase power and rate of force production and is more highly
correlated with athletic performance than strength training.
Power training methods can vary in terms of force and velocity
characteristics, since the description embraces a number of
different approaches. Plyometric jumping or throwing
exercises tend to use higher velocity and lower force, whereas
Olympic lifting exercises  eg power cleans  use higher force
and lower velocity. Between these two extremes lie ballistic
weight exercises, such as barbell squat jump and bench press
throw, which employ moderate forces and velocity.
The benefits of each method differ slightly. To summarise
simply:
1 plyometric exercises promote high movement speed, fast
twitch fibre recruitment and elastic tendon energy release;
1 Olympic lifts involve very high power outputs, high rates
of force production and increases in muscular
co-ordination of whole-body movements, such as
combined ankle, knee and hip extension;
1 ballistic weight exercises are very useful for developing
PAGE 37
PEAK PERFORMANCE STRENGTH TRAINING SPECIAL REPORT
high power in specific areas of the body  eg arm extension
power with bench press throws  and will result in high
rates of force production and muscle activity in the specific
muscle groups involved.
There is a good logical argument for training with exercises at
specific loads that produce the maximum amount of power for
that particular movement. Power has been shown by research
to be highly correlated with level of performance, and training
which develops the maximum power output will increase force
levels at the mid-to-high velocity end of the force-velocity
curve.
Exercises of this type that I recommend frequently to
athletes include power snatch, power clean, barbell squat
jump, bench press throw and heavy bag rotation throw. These
are all functional movements that involve moving moderately
heavy loads as fast as possible. To generate maximum muscular
power, a reasonable amount of load is required, and so these
exercises involve greater power output than plyometric jumps,
which use no additional load, or medicine ball throws, which
are relatively light. Max power training is a distinct discipline
and should be performed in addition to plyometric training,
not instead of it.
Research has shown that the maximum power produced on
a bench press throw or squat jump occurs with loads of around
50-60% of 1RM for the bench press or squat exercises. To
develop max power levels in the legs and upper body, you can
use 1RM test scores to determine the power training loads. For
example, an athlete with 1RM scores of 200kg squat and 120kg
bench press would produce max power on the squat jump
exercise with a 100-120kg barbell and on the bench press throw
with a 60-70kg barbell. Women may produce max power at
slightly lower levels.
The importance of quality training
When performing a max power workout, 3-5 sets of 3-5
repetitions for each exercise would be effective. Power
PAGE 38
 PEAK PERFORMANCE STRENGTH TRAINING SPECIAL REPORT
training must be high quality, as the aim is to recruit fast twitch
fibres. For this reason, it is important to take at least three
minutes rest between sets and to focus on moving the bar as
quickly as possible. Max power training performed at less
than max power simply does not work; coaches must
encourage their athletes to hit each lift with max effort, while

occurs at slightly less than the maximum load. For example, if

an athlete has a 1RM power clean of 100kg, then maximum
power will be produced around 85kg. This is probably because
most athletes do not have the time to develop the perfect
technique and timing of elite weightlifters, and tend to
produce a better speed of movement and coordination at less
than maximum load. However, as technique improves the
difference is likely to diminish.
There are great transferable benefits for athletes using
loads for the Olympic lifts that produce maximum power for
that lift. The athletes learn to feel the effort required for max
power and speed of the lift and take this increased power into
the sporting movement. This is my personal experience of the
neural and coordination effects of max power training. Again
2-4 sets of 2-5 reps with long rests are recommended.
Many athletic movements, particularly throwing and
kicking, involve trunk rotation. Rotational movements are not
possible with barbell or weight machines, but standing rotation
throws of a heavy bag (15-30kg depending on the strength of
the athlete) are very effective at producing maximum rotation
power, as they involve greater muscular force than medicine
ball exercises. The same sets, reps and rest as above are
recommended for effective training.
To summarise: the main difference between traditional
heavy weight training and power training lies in the load and
PAGE 39
PEAK PERFORMANCE STRENGTH TRAINING SPECIAL REPORT
speed of the exercises. Loads of 75-95% of 1RM will result in
increased maximum strength, while loads of 50-60% of 1RM,
performed ballistically, will result in increased maximum
power. Once an athlete has reached high strength levels,
maximum power training may be more conducive to peak
athletic performance than further increases in max strength.
Elite strength levels
How strong does an athlete need to be before the benefits of
further strength training become limited? This depends on the
individual athlete and his or her chosen event. For example,
the shot put is significantly heavier than the javelin and may
require higher max strength levels for success. As a guideline,
elite levels of strength for a male athlete are 1RM squat of
2.5-3 x body weight and 1RM bench press of 1.5-2 x
bodyweight, while those for a female are 2 and 1.25 x body
weight respectively.
Once these levels have been reached, any athlete would
probably benefit more from maximum power training than
strength training. Having said that, there seems to be
considerable benefit in combining the two methods within a

benefit
Ditmar Schmidtbleicher, a German biochemist who has

worked with Olympic athletes, advocates using high-intensity
weight training for increased rate of force development, and
claims that the results are transferable across the whole range
of the force velocity curve, as they are for novice athletes (3).
However, the quality of performance of the exercise is
fundamental to the training benefit. When using near maximal
loads for rate of force development training, athletes must
attempt to move the bar as quickly as possible, even though the
actual lift will be quite slow. That s because it is the voluntary
effort of attempting to  hit the bar hard with each repetition
PAGE 40
 PEAK PERFORMANCE STRENGTH TRAINING SPECIAL REPORT
that produces the neuromuscular benefit of increased rate of
force development, even at high loads that are normally
associated with slow speeds.
This argument is supported by recent research suggesting
there is no difference between the sprint performance benefits
derived from strength training slowly with heavy loads or fast
with moderate loads (4).
Further research suggests that for  stretch shorten cycle
movements, where an eccentric contraction precedes a
concentric contraction, maximum strength is highly correlated
with initial rate of force production in the concentric phase. By
contrast, for concentric-only movements maximum strength is
not significantly correlated with initial rate of force production
(5). Given that many sporting movements are stretch shorten
cycle in nature (see PP186, September 2003, p1), it would
appear that maximum strength is important.
The purpose of strength training
In writing this article, my aim has not been to diminish the
importance of maximum strength training for athletic
performance, but to make athletes and coaches think about a
more complete approach to strength and power training in
order to optimise performance. Remember that the purpose
of strength training for athletes is not to increase 1RMs but to
run faster, jump higher or tackle harder.
Improved performance is the ultimate goal, and power is
highly correlated with performance  possibly more so than
strength. It is logical to assume that training with exercises that
produce maximum power outputs must produce
improvements in rate of force production, muscle activation
and functional coordination that are transferable to athletic
performance.
Having said that, however, maximum strength is a precursor
to power and needs to be developed to a sufficient level to
maximise power production, particularly in stretch shorten
cycle movements.
Athletes who wish to continue to benefit from training
PAGE 41
PEAK PERFORMANCE STRENGTH TRAINING SPECIAL REPORT
programmes must vary their training. By incorporating both
max strength and max power training into a training cycle, or
periodisation, athletes can present their neuromuscular
systems with a variety of different stimuli, so enhancing the
adaptations.
The table below sets out an example workout for an elite
jumper, used during the summer competition phase. The split
squats were used to maintain max leg strength levels, while the
cleans and squat jumps were used to develop max power. After
following this programme of developing power and
maintaining maximum strength for 10 weeks, the athlete
increased power output on the power clean by as much as 10%
(from 2600W to 2900W at 90 kg).
Finally, the quality of exercise performance has a crucial
benefit on the benefits gained. Athletes must learn to make
maximum efforts, recruiting as many muscle fibres as possible.
It is also important for athletes to ensure sufficient recovery
between workouts and to plan max power training sessions for
times when they are fresh and capable of high-quality lifting.

AGEING AND SPEED
The bad news is that speed
declines with age; the good
news is that you can arrest,
even reverse, this
degenerative process
Of all the physiological variables, speed seems to get written
off most quickly as we age. Football pundits make jokes about
outfield players being  a few yards slower and goalkeepers
diving in  instalments as soon as the former hit 30 and the
latter become David Seaman.
But England s Rugby World Cup winning pack averaged
well over 30 and, despite being called  Dad s Army , still
fathered a victory; the likes of Neil Back and Martin Johnson
were certainly very speedy around the field. In track, Carl
Lewis, Frankie Fredericks, Linford Christie and Merlene
Ottey are  or were  still winning titles well into their thirties
and, in the case of Ottey, beyond. But can veteran athletes still
put in speedy sprinting performances in their forties, fifties,
sixties  and beyond?
First, let s take a look at why we slow with age. One
significant factor is a decline in muscle mass and muscle fibre
(sarcopenia). We will all experience a 10% decline in muscle
mass between the ages of 25 and 50 and a further 45%
shrinkage by our eighth decade  if we do nothing about it. To
illustrate this decline by example, the biceps muscle of a
newborn baby has around 500,000 fibres while that of an
80-year-old has a mere 300,000. As we age, we also produce
less growth hormone, which leads to reduced levels of protein
synthesis and, again, muscle atrophy. This is not the kind of
PAGE 45
PEAK PERFORMANCE STRENGTH TRAINING SPECIAL REPORT
acceleration needed by the veteran athlete in search of speed,
as decreased muscle equates to reduced strength and power
and less  oomph for sprinting.
Unfortunately, the bad news keeps on coming! Fast-twitch

all their aerobic capacity until late into their fifth decade at

least. If only it were so for their sprinting counterparts, whose
fast-twitch fibre can decline by as much as 30% between the
ages of 20 and 80.
To add another blow, creatine phosphate, that premium
ingredient for short-term activity, also declines with age. With
less quick-release energy in our muscles, we re theoretically
less able to tackle high-intensity sprint-type workouts.
Flexibility, another important physiological variable for
sprinting, also declines with age as our soft tissue hardens and
our joints stiffen.
What are the known effects on performance of these
various reductions in capacity? It gets worse! Numerous
studies have indicated that stride length declines considerably
with age. Korhonen analysed the performances of 70 finalists
(males 40-88, females 35-87) in the 100m event at the
European Veterans Athletics Championships in Jyv�skyl�,
Finland in 2000, using high-speed cameras with a panning
video technique to measure velocity, stride length, stride rate,
ground contact time and flight time (1).
Unsurprisingly, his research team discovered a general
decline in sprint performance with age, which was particularly
marked for those aged 65-70. Velocity during the different
phases of the run declined, on average, between 5 and 6% per
decade in men and 5-7% in women. Key to this decline was an
accelerating reduction in stride length and an increase in
PAGE 46
 PEAK PERFORMANCE STRENGTH TRAINING SPECIAL REPORT
contact time, with stride rate remaining largely unaffected
until the oldest age groups in both genders.
Hamilton compared 35-39-year-old runners with 90-year-
olds and found that stride length declined by as much as 40%,
from 4.72 metres per stride (2.36m per step) to 2.84m per
stride (just 1.42m per step). The implication is that the oldest
veteran sprinters may need to take almost twice as many steps
in the 100m as their younger counterparts. More positively,
though, this research group also found that stride frequency
did not decline significantly with age (2).
If you take a look at Table 1, below, you ll find some much
better news. Take note of the phenomenal times recorded by
master 100m sprinters; these indicate that it is possible to
maintain a significant amount of speed with age. So now let s
take a look at what we have to do to achieve that goal.

PEAK PERFORMANCE STRENGTH TRAINING SPECIAL REPORT
Hill training for stride length
As we ve seen, two crucial factors affecting speed decline in
the older sprinter are a reduction in stride length and an
increase in ground contact time. Hill sprinting can reverse
these negatives; the gradient will emphasis dorsiflexion (a
greater toe-up foot position) on foot strike, which will, in turn,
generate more work for the calf muscles on push off, enhancing
stride length and reducing contact time on the level. Lower
limb and ankle strength and power are crucial for sprinters of
all ages, although they can be overlooked by coaches and
athletes in favour of conditioning the quadriceps and glutes.
One of the key factors contributing to the age-related
decline in stride length is the action of the free leg as it leaves
the running surface and the foot travels a curvilinear path
beneath the body to a forward position in preparation for the
subsequent foot strike. An older runner s  return phase is
much less dynamic than that of his or her younger counterparts.
For optimising speed transference into the next running stride,
the lower leg needs to  fold up towards the butt and be pulled
through quickly and powerfully as a short lever. This action
relies on hip, glute and hamstring strength.
Returning to Hamilton s work, she and her co-workers
discovered that range of motion at the knees during running
decreased by 33%  from 123� to just 95�  between ages 35
and 90. For the oldest runners in the study, this meant that the
lower part of the leg attained a right angle with the thigh at the
point of maximum flexion, dramatically slowing free leg
transition into the next stride.
Hill sprints can play a key role in combating this lower leg
lethargy; by creating a greater leg drive, they can increase the
speed of the free leg through reaction to the ground and
condition a much more effective and speedy biomechanical
sprinting action.
Weights for fast-twitch maintenance
Weight training is crucial for mature sprinters determined to
hang on to as much zip as possible, particularly after 50 when
PAGE 48
 PEAK PERFORMANCE STRENGTH TRAINING SPECIAL REPORT
muscle mass begins to decline more steeply. Training with
weights set around 75% of one rep maximum will offset fast-
twitch fibre shrinkage quite significantly. Unfortunately,
though, it has no impact on muscle fibre reduction, which is
governed by an age-related decline in motor cells in the spinal
cord.
Weight training, by strengthening soft tissue, will also go
some way towards protecting older speed merchants from
injury.
Plyometrics for stretch/reflex
Plyometric exercises condition the stretch/reflex in our muscles
and, as well as boosting speed and power, can stimulate the fast-
twitch fibres of older sprinters into further action. As
mentioned above, stride length declines significantly with age,
and plyometrics, like hill training, offers another significant
training option for offsetting this decline. Bounding and
hopping are two very effective exercises for enhancing stride
length.

passive recovery on two occasions (4). The first effort was
completed against a resistance equal to 7.5% of body mass and
the second to 10% of body mass. Blood samples were taken at
rest, between the two sprints and one hour post exercise.
Analysis of blood samples showed that the first effort elicited
a much more significant serum GH response than the second.
PAGE 49
PEAK PERFORMANCE STRENGTH TRAINING SPECIAL REPORT
Note that, although both sprints generated the same peak and
mean power outputs, the first allowed the cyclists to generate
higher RPM scores  ie to pedal faster.
Despite the apparent attenuation of GH release in the
second effort, since speed is maintained and enhanced by
regular anaerobic training silver sprinters should benefit from
regular and above-normal GH release.
Creatine for muscle power
Intense speed and power training can also combat the normal
age-related decline in creatine phosphate. Research has shown
that anaerobic (and aerobic) training increases the production
of creatine phosphate. Research by Moller and co-workers
showed that six weeks of cycle ergometer training increased
the creatine phosphate levels of 61-80 year olds to levels
similar to those of younger adults (5). The regular anaerobic
workouts of sprint training will maintain and increase the
ability of our muscles to replenish high-energy phosphates,
regardless of age.
But since there s nothing wrong with giving Mother Nature
a legal helping hand, the older sprinter should take
supplementary creatine. Numerous studies have shown that
creatine supplementation can increase muscle power and
power maintenance over a series of anaerobic repetitions and
will contribute to the maintenance of lean muscle mass.
One interesting piece of research that specifically
addressed sprinting threw up some encouraging  and other
slightly less encouraging  information for veteran sprinters
supplementing with creatine. Schedel et al looked at whether
the improvement in maximal sprinting speed after creatine
supplementation could be attributed
to an increase in stride frequency, stride length, or both(6).
Seven sprinters completed four consecutive sprints after
one week of placebo or creatine supplementation. By
comparison with the placebo condition, creatine-fed sprinters
increased their running speed (+1.4%) and stride frequency
(+1.5%), but not their stride length.
PAGE 50
 PEAK PERFORMANCE STRENGTH TRAINING SPECIAL REPORT
This research also substantiated the use of creatine for
sustaining power output, as decline in performance of
subsequent sprints was partially prevented after supplem-
entation with creatine. The researchers concluded that their
findings could be related to the recent discovery that creatine
supplementation can produce a shortening in muscular
relaxation time, thus promoting increased sprint times.
Train smart for all-round benefits
Finally, the older sprinter needs to make use of the wiser head
on his or her shoulders. Training needs to be intense to
minimise the age-related decline in sprint speed, but it also
needs to take account of the fact that older bodies may be less
able to sustain daily, flat-out power-oriented work. Rest,
proper nutrition, supplementation and a commonsense
approach that involves  listening to the body need to be key
features of the training routine of any veteran sprinter intent
on maintaining speed.

zippy turns on the hoof
Such was the ferocity of Pete Sampras serves that they were in
danger of singeing the net; Irish and British Lions rugby centre
Brian O Driscoll swerves around opponents flat out, like a
Formula One racing car taking a bend; discus and hammer
throwers, and some shot putters, spin with the grace of ballet
dancers before releasing their implements with the power of a
nuclear strike.
Developing these explosive rotational sports skills relies not
just on innate ability and technique, but also on specialist
conditioning drills and methods. In this article, I will consider
such skills as turning, turning to sprint, turning and throwing,
and turning to hit/kick a ball or opponent, from both stationary
and moving positions.
Although all-over body power is needed to perform these
activities, the core (abdominal and back muscles) is
fundamental for their optimum performance. This area must
be strong enough to maximise the transference of power
through the limbs into a sports skill, such as a golf drive or a
tennis forehand; it must be able to withstand  and reduce the
risk of  injury in training and competition; finally (and
crucially), it must be able to generate specific sports power
itself. Agility is also fundamental to zippy turns (see article on
page 71).
It is often assumed that athletes who are fast when travelling
in a straight line will be fast in any direction. However, research
suggests that this assumption may be erroneous. Young and
associates researched the impact of straight-line speed training
PAGE 53
PEAK PERFORMANCE STRENGTH TRAINING SPECIAL REPORT
on rotational/change of direction speed, and vice versa (1).
Thirty-six males were tested on a 30m straight sprint and were
given six change of direction tests, the latter involving 2-5
tangent runs at various angles. These tests took place before
and after a six-week training period, in which one group
focused on 20-40m straight-line sprints and the other on
20-40m, 100� angle change-of-direction sprints.
What did the researchers discover about the impact of this
training on performance? Not surprisingly, the straight-line
sprinting training improved straight-line sprinting
performance. However, this increased zip did not translate
into speedier turns. In fact, the researchers discovered that the
more complex the change of direction/turning task, the less
transference there was from straight-line speed training.
Similarly, the turning/change-of-direction training gave a
major boost to turning/change of direction performance, but
had no impact on straight-line speed.
These findings have important implications for athletes and
coaches in sports like football and tennis, where players have
to constantly rotate in order to make up the ground to perform
their various sport specific skills. It seems that the ability to
rotate the body at speed is a highly specific skill, requiring
specialist conditioning, and that being fast in a straight line is
just not enough. Some of the exercises at the end of this article
can be used to condition such players  rotational muscles .
They will also benefit from specific agility training.
Rotational sport specific strength
Developing greater strength through resistance training is a
fundamental aspect of all performers conditioning routines.
Coaches and athletes alike hope that the strength developed
thereby will translate into improved sports performance.
However, this can be a very challenging conditioning
requirement for those in search of rotational power and speed.
Let s begin by considering weight training: most popular
sports conditioning weights exercises, like the squat, power
clean and snatch, are performed in a linear fashion and do not

reflect the way power is generated in a rotational sports
movement, like the discus throw. Although these exercises are
relevant in terms of establishing a power base, athletes and
coaches need to develop a repertoire of more specialist
weights exercises, such as the Russian twist and the wood-chop
(see below), which are better suited to channelling strength and
power into rotational sports skills.

Developing the  wind-up-and-rotate velocity for these
sports through weight training alone would be virtually
impossible. This poses fundamental conditioning questions,
such as: how can weights (and other resistance training
methods) be best employed to enhance specific sports
performance skill? And how important is speed of
performance? Cronin et al went in search of the answers and
reached the following conclusions (3):
1 Developing qualities like strength, power and rate of force
would appear of greater importance than training at the
actual movement velocity of a task. It may be that
(irrespective of load and limb velocity) the repeated intent
to overcome a resistance as rapidly as possible is an
important stimulus for functional high velocity adaptation;
1 Workouts should ideally combine sport specific training
with a heavy or varied training load in order to develop
the muscular and neuromuscular coordination that will
improve functional performance;
1 The ability of the nervous system to activate and
coordinate all the muscles involved in performing a
movement is essential.

timing
Throws athletes and their coaches are well aware of this

requirement and spend hours performing various rotations,
with or without resistance/throwing implements, in the pursuit
of better spatial awareness, body positioning and footwork.
Below are some examples of dynamic conditioning drills in
keeping with the theme of this article, some of them quite
unusual. Although they are performed at various velocities, all
develop the muscles used in rotational movements in a highly
sport specific way.
Weights exercises
Russian twist
This exercise mimics the shoulder rotation movement
employed in numerous hitting and throwing sports. Sit on the
floor with your knees bent to about 90� and get a training
partner to hold you down by the ankles. Holding a weights disc
PAGE 56
 PEAK PERFORMANCE STRENGTH TRAINING SPECIAL REPORT
with both hands, lower your trunk to a 120� angle, then rotate
left and right, stopping the weight at 10-15cm from the floor. If
specialist equipment that supports the body off the ground is
available to perform this exercise, you will be able to rotate
even further.
Reverse trunk twist
Lie on a weights bench face down, having positioned a barbell
across the back of your shoulders. Again you ll need a
training partner to hold your ankles down. Rotate your torso
left and right, while keeping your hips in contact with the
bench. Again, some gyms may have specialist equipment
designed for this exercise.
Cable chop
This exercise uses a high pulley machine and a triangular
attachment to develop rotational power in the shoulders and
trunk. Stand facing forward with feet slightly more than
shoulder width apart. Hold the attachment with both hands
over your right shoulder. Pull the cable across your body to just
beyond your left hip. Complete your designated number of
repetitions and repeat on the left side. This exercise can also be
performed from a kneeling position.
Resistance/plyometric drills
Plyometric drills are a crucial weapon in the rotational sports
power conditioning armoury. They lead to explosive power
development, utilising the stretch/reflex mechanism in
muscles to develop and release greater energy. A concentric
(shortening) muscular contraction is much more powerful
when it immediately follows an eccentric (lengthening)
contraction of the same muscle, and this is the basis of
plyometric training. During a plyometric drill, muscles
operate a bit like elastic bands; if you stretch the band before
releasing it, a great deal more energy is generated as it
contracts, but when there is no pre-stretch the energy output
is more  flop than  pop .
PAGE 57
PEAK PERFORMANCE STRENGTH TRAINING SPECIAL REPORT
There are a number of plyometric exercises that can be used
to boost the power capacity of the trunk (and other parts),
some of them requiring specialist items of kit.
Throwing and catching/passing a medicine ball will develop
plyometric power in the torso, legs and arms. Paul Chek one of
the world s foremost authorities on sports conditioning, for
golf in particular, recommends the following two exercises for
developing rotational power (5):
The twister
Place a small medicine ball between your legs. Holding your
arms out straight at shoulder height, take small hops and
rotate your knees to each side so that you land at an angle, first
to the right and then to the left. The greater the degree of
rotation, the greater the amount of work the obliques (the
muscles of the outer abdominal area) will have to perform.
These muscles play a key role in dynamic rotational sports skill
performance.
The medicine ball toss
This is a more familiar plyometric trunk move, in which the
performer stands side-on to a training partner (or a wall). The
move develops the plyometric stretch/reflex in the obliques
when the performer catches the ball with two hands and
rotates first away from and then towards the partner/wall
before throwing the ball back.
Tornado ball wall chop
This piece of kit  a polyurethane ball on a length of sailing rope
 was specifically developed for generating rotational power.
The  wall chop can be performed kneeling, sitting or standing,
and with varying angles of  chop . For the standing version,
position yourself about one metre away from a wall, with your
back to it. Hold the tornado ball with two hands, then rotate
and swing it, either to your left or right, so that it hits the wall. It
will, of course, spring back towards you with great force. You
need to be braced and ready to control this reaction so that you
PAGE 58
 PEAK PERFORMANCE STRENGTH TRAINING SPECIAL REPORT
can swing back into another chop immediately. It is this rapid
transference of power that evokes the plyometric response.

Twitch and you re gone 
all you need to know about
developing fast-twitch
muscle fibre for speed,
power and strength
Let s get out of the blocks straight away, with our fast-twitch
fibres blazing; on the  B of the bang, as Colin Jackson once
put it!
There are more than 250 million muscle fibres in our bodies
and more than 430 muscles that we can control voluntarily.
Fibres are, in fact, bundles of cells held together by collagen
(connective tissue). Each fibre consists of a membrane,
numerous nuclei and thousands of myofibrils (inner strands)
that run the length of the fibre.
In order to perform a sport skill numerous muscles and
muscle fibres have to interact. The process is controlled by the
brain, which sends out electrochemical messages to the
muscles via the spinal cord. These signals are received in the
muscles by  anterior motoneurons , whose role is to stimulate
muscular contraction. Muscular force is generated through the
interaction of two protein filaments that constitute the
myofibril: actin and myosin.
Anterior motoneurons and motor units can be likened to a
car s starter motor, while the brain is like the key; the former
kicks the muscle fibres into action (or rather  contraction )
after the latter has been turned.
Some muscles have large numbers of motor units and
relatively few fibres, which enables them to execute highly
precise movements. One such muscle is the eye, which has one
PAGE 61
PEAK PERFORMANCE STRENGTH TRAINING SPECIAL REPORT
motor unit for every 10 muscle fibres. By contrast, the
gastrocnemius (calf muscle), which performs larger, more
powerful movements, has 580 motor units to 1.3 million fibres.

counterparts
continually monitor muscular stretch and swing into action if,

for example, a limb is moved beyond its normal range. This is
achieved by muscle spindles  pulling back on muscle fibres to
reduce the stretch. This  stretch/reflex is a vital component of
our body s muscular safety mechanism, but it can also play a
significant role in developing greater fast-twitch muscle power
(see table 2, below).
Fast-twitch fibres, also known as  white or  type II fibres,
contract 2- 3 times faster than their slow-twitch counterparts,
producing 30-70 twitches per second, compared with 10-30 for
slow-twitch.
There are two basic types of fast-twitch fibre:
Type IIa, aka  intermediate fast-twitch fibres or  fast
oxidative glycotic (FOG) fibres because of their ability to
display, when exposed to the relevant training stimuli, a
relatively high capacity to contract under conditions of aerobic
or anaerobic energy production;
Type IIb fibres, the  turbo-chargers in our muscles, which
swing into action for a high-performance boost when needed.
These are also known as  fast glycogenolytic (FG) fibres, since
they rely almost exclusively on the short-term alactic/glycotic
energy system to fire them up.
Slow-twitch fibres, aka type I, red or slow oxidative fibres,
are designed to sustain slow but long-lived muscular
contractions and are able to function for long periods on
aerobic energy.
Most coaches and athletes will be familiar with type IIa and
type IIb fast-twitch fibres, but it should be noted that other
types have been identified. Former national athletics coach
PAGE 62
 PEAK PERFORMANCE STRENGTH TRAINING SPECIAL REPORT
Frank Dick has described a further seven sub-divisions,
although the differences between these are not considered
significant enough for them have a crucial effect on sports
conditioning (1).
Fast-twitch fibres are thicker than slow ones and it is the
former that grow in size (hypertrophy) when activated by the
 right training.
Activating fast-twitch motor units is the key to improved
strength, speed and power. Unlike slow-twitch motor units,
which are responsible for most of our day-to-day muscular
activity, fast-twitch units are quite lazy and tend to slumber
until called to action.
While typing this article, the slow-twitch motor units of my
fingers and wrists were getting a good workout. As indicated,
they are designed for repeated submaximal, often finite,
contractions. It was only when I picked up the computer, the
desk it sat on and the 30 reference books I was using to help me
write this piece, and hurled the whole lot out of the window in
abject frustration at my writing ability, that my larger fast-
twitch motor units contributed anything!
The role of mental energy
To recruit these units takes powerful movements, possibly
fuelled by an excited hormonal response associated with
increased adrenaline and neural stimulation (as with my desk
throwing). In terms of producing more power, this works
because the increased mental energy boosts the flow of
electrical impulses to the muscle, generating increased
muscular tension.
It should be pointed out that extreme levels of this  neuronal
stimulation can lead to impaired sports performance. For
example, a golfer relies on the synchronous firing of fast-twitch
motor units during the  swing ; but if he becomes overly
aggressive and  tries too hard a poor stroke usually results,
even though his fast-twitch motor units could be capable of
expressing more power because of their increased state of
tension.
PAGE 63
PEAK PERFORMANCE STRENGTH TRAINING SPECIAL REPORT
Fast-twitch muscle fibre is recruited synchronously  ie all at
the same time  within its motor unit. This is, in part, a
physiological manifestation of a neural activity  sports skill
learning. Let s use sprinting to explain this. Carl Lewis had a
wonderful silky sprint action. His finely-honed technique
allowed his fast-twitch motor units to fire synchronously and
apply power. The end result was championship and world
record-breaking form. In short, Lewis s neural mastery of
sprinting form allowed his fast-twitch motor units to fire off
smoothly, operating like cogs in a well-oiled machine. It also
allowed him to recruit the largest, and therefore most efficient,
power-producing units. This latter ability is a further key
element in developing optimum fast-twitch motor unit power.
By contrast, slow-twitch muscle motor units are recruited
asynchronously, with some resting and others firing when
carrying out endurance activity.
Fast-twitch motor units are recruited according to the  size
principle , in that the more power, speed or strength an activity
requires, the larger the units called in to supply the effort. It
would, however, take a flat-out sprint or a near PB power clean
to fully activate them. This means that power athletes have to
be in the right frame of mind to get the most out of their fast-
twitch motor units. There is no such thing as an easy flat-out

It is often assumed that those blessed with great speed or

strength are born with a higher percentage of fast-twitch

muscle fibres, and that no amount of speed work (or neuronal
stimulation) will turn a cart-horse into a race horse. But, in
fact, fast-twitch fibres are fairly evenly distributed between the
muscles of sedentary people, with most possessing 45-55% of
both fast- and slow-twitch varieties.
Thus few of us are inherently destined for any particular type
of activity, and how we develop will depend mostly on two
PAGE 64
 PEAK PERFORMANCE STRENGTH TRAINING SPECIAL REPORT
factors:
1 The way our sporting experiences are shaped at a relatively
early age;
1 How we train our muscle fibres throughout our sporting
careers.
The table below compares fast-twitch muscle percentages in
selected sports activities with those of sedentary individuals 
and a very speedy animal. Note the extremes of muscle fibre
distribution. The right training will positively develop more of
the fibres needed for either dynamic or endurance activity,
although the cheetah may not be aware of this!

Adapted from Dick page 109(1) and Williams (97)(2)
Ross et al studied motor unit changes in sprinters and
concluded that positive adaptations of muscle to sprint
training could be divided into:
1 Morphological adaptations, including changes in muscle
fibre type and cross-sectional area  ie the ability of fast-
twitch muscle fibres to exert more power by increasing in
number and/or size;
1 Metabolic adaptations to energy systems to create more
speed  eg a greater ability to complete short repeated
maximal efforts, acquired through an improvement in the
short-term alactic/glycotic energy system which is, in turn,
gained from the creation and replenishment of high-
energy phosphates (3)
PAGE 65
PEAK PERFORMANCE STRENGTH TRAINING SPECIAL REPORT
Similar finding were made by Abernethy and his team, who
compared sprint training methods with those used by
endurance athletes (4) .
Table 2, opposite, summarises the best methods for
enhancing fast-twitch motor units. Conversely, the wrong
training  and even what might in some cases seem to be the
 right training  can compromise their development.
Let s return to the sprint training research of Ross and his
team (3). They believed that volume and/or frequency of sprint
training beyond what is optimal for an individual can induce a
shift towards slower muscle contractile characteristics.
Basically, this means that if a sprinter were to perform too
many under-speed track reps, his top speed would be impaired.
What s best for power athletes
For 100% power athletes (such as 100m sprinters) and even
those involved in sports where occasional maximal or near
maximal quick flashes of power are required, such as golf,
baseball (pitching and batting) and football (goalkeeping), it
may well be that high-intensity training sessions, interspersed
with long periods of rest, are best for the optimum
development of fast-twitch motor units, particularly in-season.
This can make the conditioning process very difficult. In the
England cricket team, for example, batsmen are often
encouraged to develop their aerobic fitness by running during
down times in matches, and during pre-season. Although a
general level of aerobic fitness is useful, it is possible that too
much steady state work, particularly in-season, could blunt the
batsmen s sharpness and dull their fast-twitch motor units.
In-season it may be far better for them to condition
themselves using sprints, medicine ball work and autogenic
training (a form of mental conditioning). Think of the cheetah
in our muscle fibre distribution table. What does this fastest
land animal do? It lies around all day, exploding into action
every now and again: fast-twitch fibre development heaven 
but hell for its prey!
In support of this point, Ross s team noted that detraining
PAGE 66
 PEAK PERFORMANCE STRENGTH TRAINING SPECIAL REPORT
appeared to shift the contractile characteristics of fast-twitch
motor units towards type IIb, thus providing them with more

Training your muscles Research indicates that this form of training increases fast
eccentrically twitch motor unit recruitment.(6) An eccentric muscular
contraction generates force when muscle fibres lengthen
(see plyometric training, below)
Plyometric training These exercises utilise the stretch-reflex mechanism,
allowing for much greater-than-normal force to be
generated by pre-stretching a muscle (the eccentric
contraction) before it contracts. A hop, bound or depth
jump is an example of a plyometric conditioning drill; a
long jump take-off is an example of a plyometric sport skill.
Complex training This can induce greater recruitment of fast-twitch motor
units by lulling the protective mechanisms of a muscle
into reduced activity, allowing it to generate greater force.
Complex training involves combining weights exercises with
plyometric ones in a systematic fashion (see PP 114, Feb
1999). A good example is: 1 set of 10 squats at 75%
1RM followed, after a 2-minute recovery, by 10 jump
squats, repeated 3 times

potential  oomph . This effect can often be seen in power
athletes who sustain minor injuries after a good period of
training and are then obliged to train lightly for 2-3 weeks.
Afterwards, to their complete surprise, they often produce a
PB because the enforced rest has facilitated the fibre shift and
upped their fast-twitch potential. Other research has indicated
that a decrease in weight training after a prolonged period of
training can have a similar effect (5).
Note, though, that too long a lay-off can produce less
positive effects, due to muscle shrinkage (atrophy) in sports
where muscle size is also important, eg for shot putters and
American football line-men.

Float like a butterfly, sting

drills for boosting agility
Muhammad Ali was the greatest  period. The champ had a
superb athletic physique, awesome punching power and one of
the fastest pairs of feet and hands ever to grace any athlete, let
alone a boxer. He was so quick, he boasted, that he could flick
off the light switch and then get into bed before the light went
out! Maybe he was exaggerating his abilities here, but the
champ was incredibly agile. So what can you do to develop
equally ferocious agility?
In sport, agility is characterised by fast feet, body
coordination during change of direction and sports skill
performance, and reaction time/ability. It is an amalgam of
balance, speed, strength, flexibility and coordination. Although
a performer s agility relies heavily on the acquisition of
optimum sports technique, it can also be enhanced by specific
conditioning.
A variety of performance-enhancing agility drills, systems
and items of equipment are available to the sportsmen of today
and their coaches. The  science of agility (and speed and
power) training has made rapid strides recently, especially in
terms of its accessibility to the mainstream sporting world.

Essentially, agility training dissects a sports skill: a skill like the
fast-stepping ability required of a rugby player is broken down
into its constituent parts, which are then specifically trained.
It s all about patterning and conditioning a heightened
physical, neural, sport specific response.
Let s consider in more detail the process involved in

quickness
A wide variety of running, hopping and jumping drills can

be carried out in all directions, using the rungs of this ladder,
which is laid flat on the ground. Such drills enhance foot speed
and upper body agility, just like any other aspect of sports
performance, by progressive overload. England rugby wing
Ben Cohen has been specifically singled out as a player whose
feet have been rendered especially fleet by means of extensive
use of the rope ladder and other agility training methods.
Speed through a floor ladder can indicate much about a
player s quickness (1). A time of less than 2.8 seconds (male)
and 3.4 seconds (female) for running the length of a 20-rung
ladder, one foot in each rung at a time, is regarded as  excellent
for college athletes.
Agility training also utilises numerous other drills and items
of specialist kit; these include balance drills, slaloming in and
out of cones, and stepping over and around small hurdles. To
make the transference of the agility skill even more sport
specific, an actual sports skill can also be introduced. This
could take the form of dribbling a football in and out of cones,
or receiving a rugby pass while stepping through a foot-ladder.
More of this below.
SAQ in female footballers
Obviously, companies like SAQ International claim their
systems get results and improve players agility. But is their
confidence justified? Polman and associates looked at the
effects of SAQ techniques on female footballers over a
12-week period (2). The players were divided into three
groups, two performing SAQ training, while the third carried
on with their normal conditioning programmes. The results
were as follows:
PAGE 72
 PEAK PERFORMANCE STRENGTH TRAINING SPECIAL REPORT
1 All three interventions reduced the participants body
mass index (-3.7%) and fat percentage (-1.7%), and
increased flexibility (+14.7%) and VO2max (+ 18.4%);
1 However, the SAQ groups exhibited significantly greater
benefits from their training programme than the other
group on a sprint-to-fatigue test, a 25m sprint, and left
and right side agility tests.
Working to improve the agility of a dynamic sports
performer (like a footballer or rugby player) by means of SAQ
and similar techniques seems highly appropriate, relevant and
valuable. But will the same principles apply to endurance
athletes? After all, quick-as-a-flash agility is not a pre-requisite
for triathlon or marathon running.
Alricsson and associates carried out a study to evaluate
whether dance training had any effect on the joint mobility and
muscle flexibility of the spine, hip and ankle and on the speed
and agility of young cross-country skiers (3). Cross-country
skiing is a not a sport renowned for quick dynamic movement,
but shaving seconds off on every turn and jump could add up to
significant time savings. Dance training was selected for this
task because of its potential contribution to agility and
flexibility.
The study involved 20 elite cross-country skiers, aged 12-15,
with half of them (five girls and five boys) receiving weekly
dance training and the rest serving as non-dancing controls for
a period of eight months. Joint mobility and muscle flexibility
of the spine, hip and ankle were measured before the study
period and at three and eight months. Two sport-related
functional tests  a slalom test and a hurdle test  were carried
out at the same times.
The researchers found that the dance group had increased
their speed by a total of 0.3 seconds over the slalom test after
eight months. They also improved their speed and agility on
the hurdle test by 0.8 seconds after three months and by a
further 0.6 seconds after eight months. Furthermore, they
increased flexion-extension of the thoracic (upper) spine by
7.5� after three months and by a further 1.5� after eight months,
PAGE 73
PEAK PERFORMANCE STRENGTH TRAINING SPECIAL REPORT
while lateral flexion improved by 0.04mm and a further
0.03mm over the same periods. Meanwhile, the non-dancing
controls did not show any improvements in any of the studied
variables.
Effects of dance training
Alricsson concluded:  Dance training has a positive effect on
speed and agility and on joint mobility and muscle flexibility in
flexion-extension and lateral flexion of the spine in young
cross-country skiers . Had his subjects made use of more sport
specific agility training, the chances are that their gains would
have been even greater.
Marathon runners do not have to dart sideways, backwards
and forwards with lightning speed over the course of their
26-mile effort, so could they have anything to gain from agility
training? To answer this question, we need to consider the
interplay between agility and power training.
Research indicates that, despite prolonged running
training, runners leg muscles may not actually be that efficient
at returning energy to the running surface. In fact, at certain
speeds these muscles may be working at only 50% efficiency
because of the  natural energy return effectiveness of the foot
arch and Achilles tendon (4).
It s a bit like having an engine turbocharger that works in
reverse. Your Achilles and foot arch are the turbo: they cut in
automatically when your foot strikes the ground, producing a
burst of power but leave the running muscles (quads,
hamstrings and calf muscles  the engine) working at less than
their full potential. Unless you target these running muscles
with specific power conditioning drills, your ability to drive up
running speed can be compromised.
Such exercises as hopping on and off of a low box and spring
jogging (virtually straight leg movements, where the performer
propels himself forwards primarily by means of feet and ankles)
not only develop  harder , and therefore more effective,
running muscles through their plyometric effect, but also
improve agility.
PAGE 74
 PEAK PERFORMANCE STRENGTH TRAINING SPECIAL REPORT
Plyometric exercises enable muscles to generate huge
amounts of force in a split second, when a concentric
(shortening) muscular contraction immediately follows an
eccentric (lengthening) contraction of the same muscle. These
agility and power moves can  sharpen foot/ground contact and
result in a more economical and powerful running stride,

patterns required for their sport and to use this information to

construct the most relevant conditioning programme. In this
respect foot positioning can be crucial.
Kovacs and associates looked at the relevance of foot
positioning, particularly foot-landing positions, in athletes
performing plyometric depth jumps drills involving stepping
off a box then immediately springing upwards, sideways or
forwards (5). Specifically, the researchers were interested in
comparing the force generated by flat-footed and forefoot
ground contacts.
Ten male university students performed two types of depth
jump from a 0.4m high box placed 1m from the centre of a
force plate. They were instructed to land either on the balls of
their feet, without the heels touching the ground, or on their
heels. The researchers discovered that the two different
jumping styles generated force in very different ways. Using
specific measuring equipment, Kovacs team demonstrated
that a forefoot landing depth jump produced significantly
more power at impact and at the transition into the jump than
a flat-footed landing depth jump.
PAGE 75
PEAK PERFORMANCE STRENGTH TRAINING SPECIAL REPORT
Depth jumps and power
Kovacs findings have crucial implications for optimum agility
and power conditioning. Even though a flat-footed-landing
depth jump will develop power, this may not channel optimally
into enhancing the agility and power of a player in a specific
sport. For example, a sprinter would probably benefit more
from forefoot-landing jumps, as the sprint action is performed
from a similar foot-strike position, whereas a basketball or
volleyball player is likely to develop greater vertical spring  a
key requirement of the games  by using flat-footed landings.
Muscle firing patterns are very specific, and conditioning drills
must mirror sports skills for optimum results.
Finally here s an example of an even more specific agility/
power conditioning drill, designed for a tennis player. The
player should perform a depth jump with a forefoot  but non-
aligned  landing position, which will enable him or her to
rotate and sprint, in 3-5 strides, to a designated target to the
left or right.
This drill mimics and conditions the typical agility (power
and speed) required in a game situation  eg to reach a drop
shot. And it can be made even more specific if the player holds
a racket and  ghosts a shot on reaching the designated target.
In summary, if you or those you coach want to become
faster, more elusive, more efficient and more dynamic in their
movements, it is advisable to incorporate specific drills into
regular training routines.

SPEED DEVELOPMENT
Tried and tested ways to
fast-forward your sporting
performance
Billy the Whiz, the Flying Scotsman and the Kansas Cannonball
all have something in common apart from great nicknames: they
all have  or had  great speed. In their human incarnations,  the
Whiz is Jason Robinson, the staccato-footed speed merchant
who plays either wing or full back for England s rugby union
side; Allan Wells is the Flying Scotsman, fast enough over 100m
to win Olympic gold in just over 10 seconds back in 1980; and
Maurice Greene (the Kansas Cannonball) is, of course, the
former World 100m record-holder.
These athletes move, quite literally, in the blink of an eye.
Like many of us in search of that most precious sporting
commodity, speed, all have made use of a variety of techniques
and equipment aids to sharpen them up. This article
investigates some of these to help you gain some insight into
how to fast-forward your sporting performance.
SAQ drills
SAQ (an acronym for  speed, agility and quickness ) is the title
of a system patented by a company called  SAQ International ,
which works in the UK with top football teams like West Ham
United and the Rugby Football Union, and internationally
with the likes of the Miami Dolphins American Football team
and the New South Wales Waratahs rugby team in Australia.
Jason ( the Whiz ) Robinson has two of the fleetest feet seen
on a rugby player and, although blessed with innate ability to
dance rings around his opponents, he has also honed his agility
through the use of such SAQ drills as the  foot ladder . This
PAGE 79
PEAK PERFORMANCE STRENGTH TRAINING SPECIAL REPORT
type of rope ladder, a key component of SAQ training, is
placed flat on the playing surface in order to develop foot
speed and improved foot-ground contact.
There are numerous permutations of ways for athletes to step
and run through the ladder, which can challenge the fast twitch
fibres of even the fleetest athletes.  One foot in, one foot out
(left, right, left into each rung) is not too difficult;  two in, two out
(two feet one after the other into each gap) is more challenging;
but backwards and sideways combinations definitely need to
engage the brain as well as the feet. It s a bit like learning to waltz
against the high-speed rhythm of Garage music!
These drills, like many of the speed-enhancing techniques
mentioned in this article, are designed to optimise
neuromuscular patterning and condition. Like any other physical
attribute, speed can be trained and improved through repetition
and overload. SAQ techniques never lose sight of this overall
goal and the playing requirements of various sports. Depending
on their emphasis, the drills are designed either to develop
absolute speed and agility or to develop these attributes under
the conditions of fatigue that players experience during a match.
Drills with a sport specific emphasis often shape up looking
like an obstacle course, involving short swerves through cones,
hopscotch, zig-zag runs, long swerves, two- footed jumps over
low hurdles, backwards running and turns through 360
degrees. Players are often required to perform even more
sport-specific tasks during the course of these workouts; for
example, a rugby player might have to receive and pass the ball
while running through the foot ladder.

The Frappier acceleration programme
The Frappier system is a more mechanised version of SAQ 
think Terminator rather than Tarzan  which was described in
detail in a recent issue of Peak Performance (PP169 August
2002). It relies on high-tech kit like the  Plyo-Press , the  Multi-
Hip , the  Upper Body Implosion Unit and the  Super
PAGE 80
 PEAK PERFORMANCE STRENGTH TRAINING SPECIAL REPORT
Treadmill . The system is the brain-child of American John

development
Back in the States, Frappier began working with top NFL

(American Football) players and opened his first Acceleration
Training Centre in 1986. Today there are more than 100 such
centres, mostly in the United States.
The Frappier system applies the principles of controlled
overload to speed development. All athletes, whatever their
sport, are put through a six-week  level one programme, which
identifies their individual strengths and weaknesses and
introduces them to the programme s protocols, and particularly
the use of the  Super Treadmill . Those in search of scintillating
speed are progressed through a 12-level programme, while
those seeking sustained speed endurance work through six
levels. Both programmes use eight-week training cycles, with 3-4
sessions a week. Speed workouts use the treadmill, while
conditioning routines involve other items of specialist kit as well
as more  everyday sports and speed conditioning drills.
After the six-week introductory course, the Frappier system
claims that you can expect, on average, a two-tenths-of-a-
second improvement in 40 yards time and a 2-4 inch
improvement in vertical jump ability.
The 28mph Super Treadmill is the key to the Frappier
system, since it allows for the performance of flat and inclined
running (up to 40%) under controlled conditions. The
acceleration coach is able to stand alongside the athlete,
offering verbal and uniquely physical support. A carefully-
placed hand to the lower back can  spot or support the
sprinting athlete, leading to the maintenance and development
of biomechanically correct form.
The Plyo-Press is perhaps the most interesting of the other
specialist pieces of speed-enhancing equipment employed by
PAGE 81
PEAK PERFORMANCE STRENGTH TRAINING SPECIAL REPORT
the Frappier system. It combines weight-based resistance
training with plyometric training in one hit, allowing athletes
to strengthen their muscles in a highly speed-specific way. You
select the appropriate weight from the weights stack in the
same way that you would on a piece of standard fixed weight
equipment, then lie on your back with the machine s pads
behind your shoulders within a sort of track. From this
position, you are able to generate the power to push yourself
towards a footplate that you then  react against through your
lower and upper legs to launch yourself back up the track.
Conditioning this  stretch/reflex is perhaps the key to
developing the power to move over a playing surface like a
racehorse rather than a donkey. In sprinting, there are three
stretch/reflex reactions, occurring at the ankle, knee and hip.
If you can succeed in minimising the  amortisation phase (the
gap between impact/stretch and power expression/
contraction) you will be a faster, more powerful athlete. The
Frappier system is designed to help you achieve this (1).
For further information on the Frappier system, go to www.
sportdimensions.com
Uphill sprinting
The Frappier system, being true to its high-tech principles,
tends to eschew nature s hills for mechanised ones. But uphill
sprinting, wherever it takes place, is a great way to develop
speed. For best results you need a 30% gradient, which will
optimally overload the ankle dorsiflexors and plantarflexors,
the knee flexors (during the swing phase), the knee extensors
and the hip extensors and flexors (2). This degree of incline
also results in greater range of motion at the hip and ankle,
faster joint motions during push-off and 2-3 times greater
neuromuscular activity in the hip and knee extensors.
Downhill sprinting, elastic cord sprinting and
the concept of  over-speed
If uphill sprinting provides such a great speed-enhancing
opportunity, what about turning round and sprinting downhill?
PAGE 82
 PEAK PERFORMANCE STRENGTH TRAINING SPECIAL REPORT
This activity will result in what is known as  over-speed running.
Greene is aptly nicknamed the Kansas Cannonball, and during
his training it s more than likely that he will have used over-
speed downhill running and other over-speed methods to reach
speeds he would not normally be able to attain.
Other over-speed devices include towing methods,
running  with the wind and elasticised harnesses. These
devices are essentially giant rubber bands that are attached
around the waist. Tension is built up by pulling them out (you
need a coach or another athlete to do this); when the harness
is released, the athlete is pulled down the track beyond his or
her normal sprint speed.
All over-speed methods push or pull athletes to speeds they
would not be able to achieve using their bodies alone.

Having tried most over-speed methods myself, I have found
that downhill running using a slight decline (10% or less)
seemed to offer the greatest transference to my sprinting
capability. Elasticised harnesses (read catapults), although
great fun, were rather like roller-coaster rides: very
exhilarating and scary at the time but easily forgotten, with
only marginal consequent improvement to my sprinting
speeds. Downhill sprinting, however, enabled me to fire my
own muscles, and because of this there was greater
transferability to my on-the-flat sprinting.
The old Eastern Bloc countries were quick to realise the
benefits of sprinting on various gradients. A trip to their
former training facilities  such as Potsdam in East
Germany, where they had constructed incline/decline sprint
PAGE 83
PEAK PERFORMANCE STRENGTH TRAINING SPECIAL REPORT
tracks  makes this perfectly clear. To achieve optimum
speed transference, Eastern Bloc trainers would get their
athletes to sprint uphill one week, on the flat the next and
downhill the next.
Specific speed conditioners
1. The Powerbag
This is a relatively new item of speed and power-enhancing kit,
which is used by the England rugby team, among other elite
performers, and has only very recently been launched to the
wider fitness market. Powerbags are tubular padded sacks made
from a rip-stop vinyl, with webbing handles at shoulder width,
which enable them to be easily carried, lifted and thrown.
Powerbags, which come in various weights, specifically
address core stability, balance and the recruitment of the body s
stabilising muscles  all key elements of speed and sport specific
conditioning. In terms of speed development, they come into
their own when conditioning explosive upper body power.
No matter how powerfully you might perform a traditional
upper body resistance exercise, like the shoulder press, it is
very likely that you will  hold back as you come to the end
point of the press, simply because you won t be able to follow
through as you would when throwing or pushing an object.
With a Powerbag, you can safely condition this explosive,
speedy response because you can throw it. The bag can even be
caught by a partner and thrown back to develop upper body
plyometric power in another way.
For further information on the Powerbag, e-mail mail@
performt.com or go to www.performt.com
2. Speedballs
Allan Wells was a great advocate of the  boxer s speedball,
believing that it enhanced his upper body speed and power.
There is no doubt that it would have conditioned such a
response (Wells being no slouch) but the drawback was that
the firing pattern of the muscles of the upper arms and chest
were developed in an opposite direction to that required for
PAGE 84
 PEAK PERFORMANCE STRENGTH TRAINING SPECIAL REPORT
the sprinting action. However, the speedball does have its
merits as a pre-conditioner and neuromuscular  sharpener 
and it s great to work out with to the theme from Rocky!
Speedballs can be obtained from specific fitness retailers.
3. Foot-flexor devices
Foot-Flexor devices aim to secure the foot in a dorsiflexed
position during sprint training and are attached around the
sprint shoe to the ankle. The theory behind this form of sports
bondage is that it encourages sprinters to run with their toes up
rather than down, which contradicts the older coaching
wisdom that sprinters should run high on their toes.
Proponents of dorsiflexed sprinting believe that it
maximises force return from the running surface, thus
enhancing forward locomotion. A toe-down position is seen to
 break the sprinting motion because the lower limbs will yield
as the feet strike the ground, no matter how strong the athlete s
calf muscles.
The devices themselves may be somewhat overrated, but
the dorsiflexed foot position is not; you really do get a feeling
of greater power return from the track while running toes up,
and the foot has to be  coming back toward you to optimise
push off. However, concentrated toes-up sprinting needs to be
gradually introduced into an athlete s training programme to
avoid injury.
Foot-Flexor devices are available through SportDimensions
(see above).
If speed is your goal why not try out some of the above-
mentioned training methods and systems. You could even
come to deserve your own great speed related nickname!

WHAT THE SCIENTISTS SAY
Reports on recent conditioning-related studies by
Isabel Walker and Raphael Brandon
Eccentric moves recruit most fast
twitch fibres
A new piece of research has investigated the differences in activation
patterns between concentric and eccentric quadriceps contractions.
In particular, the researchers were concerned with measuring the
amount of muscle activity as revealed by electromyography (EMG)
and the mean frequency of the EMG signal.
As a rule, the larger the EMG signal recorded the more muscle
fibres are being recruited, while the frequency of the signal is an
indication of how fast they are being recruited. Research has shown
that higher frequency EMG is consistent with greater fast twitch fibre
recruitment.
Concentric contraction involves force created when the muscle
fibres shorten, while eccentric contraction involves force created
when they lengthen. For example, when you land on two feet from a
jump and bend your knees, the quadriceps are lengthening but also
creating a force to control the landing. As you spring back from the
landing, extending your knees and jumping back up in the air, the
quadriceps are shortening as they create force to push you off.
In this experiment, the subjects performed maximal concentric
and eccentric contractions of the quadriceps, while the researchers
measured the EMG activity and frequency of signals. They found that
the total EMG signal was greater during the concentric phase 
suggesting more muscle fibres are active at this time  while the
mean frequency of the EMG signal was greater during the eccentric
phase  suggesting more fast twitch fibres are being recruited at this
time.
They concluded that during a maximal eccentric contraction there
is less total muscle fibre recruitment, with fast twitch fibres recruited
PAGE 87
PEAK PERFORMANCE STRENGTH TRAINING SPECIAL REPORT
in preference to slow twitch ones, whereas during a maximal
concentric contraction all the muscles fibres are used.
This finding is significant for power athletes: if you want to train
your fast twitch fibres it would seem that eccentric contraction
movements are more useful than concentric ones.
Plyometric exercises, which involve high-force eccentric
movements, would be particularly useful for this purpose. A good
example is the depth jump, which involves jumping off a box, bending
at the knee and hip to control the landing softly, then jumping back
up. The landing phase is the eccentric contraction  and the bigger
the depth jump, the greater the eccentric forces.
Power athletes may also want to consider performing strength
exercises using the eccentric phase only. By this means you may be
able to target just the fast twitch fibres and perform less total work,
potentially making the training more efficient. You will need a training
partner or coach to assist you with each concentric phase, leaving you
to complete the effort on each eccentric phase alone.

ATP is no creatine
The search for the  new creatine continues  but ATP seems unlikely
to fit the bill if the results of a new US study are anything to go by. ATP
(adenosine 5-triphosphate), found in every human cell, is the body s
universal energy donor. It also plays a key role in a number of other
biological processes, including neurotransmission, muscle
contraction, cardiac and circulatory function and liver glycogen
metabolism.
So it is not too far-fetched to assume that supplementary ATP
might offer some useful ergogenic benefits for athletes, particularly
enhanced anaerobic capacity and muscular strength.
That was the theory these researchers set out to test with a study
of 27 healthy men, randomly split into three equal groups receiving
one of the following oral supplements for 14 days:
1 Low-dose ATP (150mg);
PAGE 88
 PEAK PERFORMANCE STRENGTH TRAINING SPECIAL REPORT
1 High-dose ATP (225mg);
1 Placebo.
Because supplementary ATP is not easily absorbed by the body, the
supplements were coated in a methylcellulose  shell designed to
protect the molecule during its passage through the gut.
Anaerobic power (via the Wingate cycle ergometer test), muscle
strength (via the bench press) and total blood ATP concentrations
were measured under three conditions:
1. Baseline (before the supplementation regime began);
2. Acutely (seven days later, before and 75 minutes after ingestion of
the first dose);
3. Post (after 14 days of daily ingestion).
Statistical analysis of all the data showed no significant effects of
supplementation on blood ATP concentrations or anaerobic power
either between or within groups. However, some improvements in
measures of muscle strength were observed after treatment in the
high-dose ATP group, although the researchers acknowledge that
these effects were small and quite possibly spurious.
Interestingly, people in the high-dose group (who were, of course,
blinded to which supplement they were receiving) reported feeling
better during treatment. This improvement in sensation is
physiologically plausible, the researchers point out, as  ATP and
associate nucleotides have been shown to affect brain levels and
release of noradrenaline, glutamine and serotonin and hence
modulate mood and other responses& 
Nevertheless, they question the practical usefulness of the small
improvements they observed and conclude that further research is
needed before ATP supplementation can be recommended as an
ergogenic aid.
