Are There Relationships Between
Acceleration, Maximum Speed, and
Vertical Jump Performance?One of the most widely performed tests for explosive
characteristics of the lower body is the countermovement
vertical jump (CMJ). When performed on a force plate with
position transducers without arm swing, the CMJ can be
used with a variety of loads to create a power profi le. While
many studies have been performed relating jumping per-
formance to sprint or speed performance there is a lack
of clarity on which variables are the best to assess in an
athlete monitoring program. Recently, researchers from
Australia attempted to determine the relationships be-
tween selected jump variables, acceleration and maximal
running speed in an attempt to determine which variables
are of key interest. Twenty-three Australian football play-
ers performed three maximal vertical jump trials, with the
best trial being utilized in the analysis of force time curve
variables. Position transducers were used to quantify ver-
tical displacement and peak barbell velocity, while a force
plate was used to measure ground reaction forces. Peak
power was determined by multiplying the vertical velocity
by the ground reaction forces. Times of 40-m sprints were
determined with the use of an electronic timing system.
Split times were determined at 10 and 20m. Acceleration
was determined at the 0 – 10m interval, while the maxi-
mum speed was estimated from the 20 – 40m interval.
When the results were analyzed it was noted that vertical
jump height was moderately (-0.430, p <0.041) correlated
with acceleration from to 10m, while maximal running
speed had a large correlation with the peak power output
per kilograms of body weight. As a whole, the correlations
between CMJ variables and maximal speed were stronger
than those obtained with acceleration. Based upon these
data it appears that when monitoring athletes with a force
plate and position transducer system the most important
variables to quantify are the jump height and relative peak
power output.

variables should be used to assess explosive leg muscle
function? Int J Sports Physiol Perform 6: 51 – 57, 2011.
Does Training History Affect the
Optimal Load for Maximizing Power
Output?The quantifi cation of maximal power output (MPO) is
often assessed when monitoring athletes. There are nu-
merous tests which can be employed including complex
movements such as cycling, running, and jumping tasks.
Since MPO is a function of the maximal force, or strength,
and velocity of shortening a muscle can undergo, it is
widely believed that there is an optimal load for produc-
ing a MPO. While this theory is widely accepted there is
much debate about the eff ect of training history or status
on the external load required to result in a MPO. Recently,
a research study examined the optimal load and the ef-
fect of training history on the optimal load necessary to
result in a MPO on a 6-sec maximal sprint cycling test.
Forty healthy young men from a variety of training back-
grounds were recruited to determine the optimal load and
eff ect of training history of MPO. Specifi cally, the subject
groups contained 10 strength trained, 10 speed trained,
10 active, and 10 sedentary subjects. All subjects had their
1RM back squat assessed with standardized procedures as
well as performed 8 randomized 6secs sprint tests against
diff erent percentage body weight loads. Each sprint was
separated by 4mins. When the data were analyzed it was
determined that the 1RM back squat was the highest for
the strength trained group (206±19.2kg) followed by the
speed group (163±19.2kg), the active group (131.8±9.1kg)
and the sedentary control group (116.0±17.3kg). When
the comparing the various groups, the strength trained
group produced the highest MPO, while the sedentary
control group produced the lowest. When looking at the
optimal load for producing MPO it was determined that
9.7% body weight resulted in the highest MPO in the
strength group, 9.2% body weight resulted in the high-
est MPO in the speed group, 9.7% body weight resulted
in the highest MPO in the active group, and 8.0% body
weight resulted in the highest MPO for the sedentary con-
trol group. As a whole, the present data can be interpreted
in several ways. First, it appears that training history has
an impact on the optimal load for producing MPO, spe-
cifi cally stronger athletes produce MPO at higher percent-
ages of body weight, while weaker individuals produce it
a lower percentages of body weight. Second, increasing
strength levels can result in a maximization of MPO. There-

Strength and Speed Training Improved
Functional Performance of Elders with
Mobility DisabilityWhen strength and conditioning exercises are applied in a specifi c way to
target a participant’s specifi c impairment, it appears to be an eff ective reha-
bilitative method. Recently, researchers from the University of Texas Medi-
cal Branch in Galveston, TX wanted to examine the eff ects of a function-fo-
cused intervention consisting of strength training and gait speed training
on walking speed, walking endurance and functional impairment. Twelve
functionally impaired adults (mean age = 77.2±7.3yrs) who demonstrated
impaired gate speed (<0.85m/sec), walking speed (<305m in 5mins), and
who were functionally impaired were recruited as subjects. Each subject
performed 75mins of training three times per week for 12 weeks of gate
speed training, walking exercise, and functional strength training. Walking
training consisted of 5 – 10secs of fast walking interspersed with stand-
ing rests and a period of moderate intensity walking (5mins). Gate speed
training consisted of multiple trials of walking for 10secs at the individual
subject’s maximal gait speed as determined by a pre-testing treadmill test.
The speed of training was progressively manipulated across the duration
of the study. Functional strength training consisted of sit-to-stand exercise
(5mins, 10 – 12 reps), lunges (5mins, 10 – 15 reps), ankle plantar fl exion
(5mins, 10 – 20 reps), bridging (5mins, 10 – 20 reps), fl oor transfer (5mins,
1 – 5 reps), and knee bends (5mins, 10 – 15 reps). After the 12 weeks of
training subjects demonstrated improved gait speed (≥1.0m/sec), walking
endurance (≥350m), and functional ability (≥10 score on performance bat-
tery) which placed them into a normal functioning category. As a whole,
this data indicates that a focused training plan can signifi cantly impact the
quality of life and mobility of frail older adults.

Does Body Fat Percentage Affect Physical and
Physiological Performance in Army Soldiers?
There is a large amount of debate about the optimal body composition
for military personnel. While strength power athletes may require higher
lean body mass, and endurance athletes may require lower body weights
and fat masses, tactical athletes appear to require both attributes. To ex-
plore the role of body fat on performance a research study explored the
diff erence in performance on physical and physiological tests of tactical
athletes meeting the Department of Defense’s body fat goal (≤18%) and
those exceeding this requirement (>18%). A total of 99 tactical athletes
were recruited and tested on a battery of performance tests. Tests in-
cluded a Wingate anaerobic cycle test, an incremental treadmill run test,
isokinetic tests for knee fl exion/extension and shoulder internal/external
rotation strength, and the Army Physical Fitness Readiness Test. The Army
Physical Fitness Readiness Test included push-up and sit-up tests which
required the tactical athletes to perform as many repetitions as possible
in 2mins, followed by the amount of time needed to run a distance of 2mi.
When the data were analyzed the tactical athletes were divided into two
groups. One group (n=44) had an average body fat of 13.3±3.7% while the
second group (n=55) had an average body fat of 26.0±5.4%. Group one
performed signifi cantly better on the anaerobic capacity test, the maxi-
mal aerobic power test, the push-up test, isokinetic shoulder internal and
external rotation tests, and the isokinetic extension and fl exion test. There
were no diff erences between the groups for the sit-up test, the 2-mi run
time, or the peak anaerobic power test. When tactical athletes with similar
fat-free masses were compared the tactical athletes with less body fat had
improved aerobic and anaerobic capacity as well as increased muscular
strength levels. This data suggests that leaner soldiers are able to perform
better on tests which have been found to relate to military service. n

A decade ago, when asked whether or not an athlete
could improve speed, most would have answered with an
emphatic, “no.” Yet, advancements in sports science and
biomechanics research and a proper goal-specifi c pro-
gram can truly make a diff erence. Improvements in run-
ning mechanics are vital and most commonly address im-
proving speed. There are three less discussed “secrets,” or
steps, to speed development that involves training on the
fi eld, in the weight room, and in the kitchen. By training
primarily in the acceleration phase, training the posterior
chain muscles, and dropping body fat an athlete can make
a substantial impact on speed development.
The acceleration phase of training should be the primar-
ily focus because most athletes never reach top speed in
sports, let alone maintain it. This is because of variables
like the fi eld or court length or that the sport involves a
lot of directional changes and lateral and backward move-
ment. Most competitive athletes reach maximal velocity
at 40 – 60m; however, the majority of acceleration takes
place within the fi rst 25m (1). Therefore, an athlete should
focus most of their training volume towards the accelera-
tion phase by performing quick bursts within a shorter
distance.
Exercises that address the posterior muscles can contrib-
ute to the development of speed as well. Many times the
posterior muscles are neglected by athletes who simply
run, use speed ladders, and work on the anterior muscles.
The posterior muscles are actively involved when sprint-
ing. For example, the gluteals extend the hips when sprint-
ing, and if an athlete is not able to activate their gluteals
when sprinting their hamstrings may take over, which can
lead to injury and slower, less effi cient results. An athlete
should try exercises like single-leg Romanian deadlifts,
kettlebell swings, standing single-arm rows in a staggered
stance, and explosive plyometic moves like plyolunges.
These exercises promote the proper movement patterns
associated with speed and power development.
Lastly, if an athlete wants to improve speed, they may
want to drop the unnecessary excess body fat. The quick-
est animals in the world are lean, fi t, and conditioned.
For example, one will never see an obese thoroughbred
horse at the Kentucky Derby. The intent behind dropping
body fat is to drop unnecessary body fat not simply scale
weight. An elite sprinter’s physique carries plenty of lean
muscle in comparison to a distance runner. A simple, sub-
clinical way to test this theory is for an athlete to run a
timed 40-yd dash (the staple test for measuring speed)
and record the subsequent score. Then include weighted
training vest (20lbs) and repeat the test. The athlete will
notice not only how much more diffi cult the task is, but
how much harder it is to breathe.
Improving the quality of training in these three areas will
help athletes improve speed development and show no-
ticeable results if incorporated into a training program
properly. n

Resistive Training forSpeed Development
There are many methods for developing speed through
the use of shoulder and waist harnesses, the use of
hills, weighted vests, resistance suits, and/or parachutes
(1,2,3,4,5,6). The aim of these training methods is to ei-
ther improve stride frequency or acceleration in sprinting.
What many of these training methods aim to improve is
the strength of the quadricep, hamstring and gluteal mus-
cles in order to generate more functional running speed.
The following training exercises emphasize functional
strength development as it pertains to sprinting using a
variety of training techniques and can be included in vari-
ous training programs to develop speed.
Parachute sprintingBegin by properly securing a parachute training appara-
tus to the athlete and reserving a minimum of 40yds of
fl at, sprinting surface (e.g., training fi eld, track). A 3-point
stance or a standing start may be utilized based on pro-
gram design. Have the athlete sprint against the wind, if
possible, with the parachute at 50% of their maximum
speed for three sprints. Once the athlete has completed
this set, have the athlete sprint in the same fashion but
this time at 75 – 85% of their maximum speed. See Fig-
ures 1.0, 2.0 and 3.0 for proper execution and technique
for parachute sprinting.
Weighted sled sprintingA waist harness is placed on the athlete to begin this ex-
ercise which is attached to sled with weight correspond-
ing to the program design. A level surface a minimum of
40yds should be designated for the athlete to pull the
sled. The exercise requires the athlete to sprint at 50% of
their maximum speed for three sprints. Once the athlete
has completed this set, the athlete sprints in the same
fashion but this time at 75 – 85% of their maximum speed.
See Figures 4.0, 5.0 and 6.0 for examples.
Harness resistance sprintingTo begin this exercise, a strength and conditioning coach
provides resistance to a harness or resistance band fas-
tened around the waist of the athlete. Once again, a mini-
mum of 40yds should be designated to performing this
exercise. In this exercise the athlete sprints at 50% of their
maximum speed for three sprints. Once the athlete has
completed this set, the athlete sprints in the same fashion
but this time at 75 – 85% of their maximum speed. See
Figures 7.0 and 8.0 for examples.
Isolated cable leg driveson a stability ballThe athlete begins by lying back on a stability ball with
the right ankle attached to a cable cross-over machine.
While maintaining balance on the ball with the left leg on
the fl oor, for balance, have the athlete drive with the right
leg. Perform 3 – 4 sets of six repetitions on each leg. Fig-
ures 9.0 and 10.0 provide examples of proper execution
of this exercise.
Isolated cable leg driveson a BOSU Have the athlete lay back on the blue dome of a BOSU ball
with their right ankle attached to a cable cross-over ma-
chine. While laying back on the BOSU and the left leg on
the fl oor, have the athlete drive up with the right leg. Per-
form 3 – 4 sets of six repetitions on each leg. See Figures
11.0 and 12.0 for examples.
Isolated cable leg drives while standing on the flat surface of a BOSUHave the athlete stand on the fl at surface of the BOSU
with the right ankle attached to a cable cross-over ma-
chine. While standing and maintaining balance on the left
leg, have the athlete drive up on the right leg. Perform 3 –
4 sets of six repetitions on each leg. Figures 13.0 and 14.0
provide examples for proper execution.

leg, have the athlete drive up on the right leg. Perform 3 – 4 sets of six rep-
etitions on each leg. See Figures 15.0 and 16.0 for examples.
The aim of this article is to provide a variety of resistive training options in
the development of speed. The emphasis is on functional strength sprint-
ing through the use of parachutes, weighted sleds, harnesses, and isolated
leg drives using cable resistance. The use of tubing, parachutes, incline
sprints, and harnesses still need to be applied with proper technique to
ensure there are no changes to the sprint mechanics of the athlete (1,2).
These exercises provide strength and conditioning coaches and athletes
with a variety of indoor and outdoor training methods for developing
strength and power in the development of speed. n

Tools for Speed DevelopmentSpeed development is an important element of an ath-
lete’s physical preparation. While it is true that not all
athletes are sprinters, speed is important to develop be-
cause it allows an athlete to arrive somewhere faster. This
quality gives them an edge for making a play, eluding a
defender, getting to the ball, or whatever their specifi c
sport demands. As a result, speed is widely assessed and is
something that coaches look for at every level of athletics.
This article provides an overview of the major tools used
in speed training and discusses how these change as an
athlete’s level of development changes.
There are a number of tools that are used to enhance an
athlete’s speed, but not all of these are equally relevant to
every sport and every level of development. These tools
include:
• Technique drills
• Explosive starts
• Sprints of varying distances
• Resisted sprinting
• Assisted sprinting
• Varied-pace sprinting
• Stride length drills
• Stride frequency drills
According to research, there is a progression of technique
drills focused on breaking the sprinting motion down
into more manageable components (1). This progression
includes ankling drills, which teaches how to pick the
foot up off the ground; heel-kick drills, which reinforces
ankling and teaches how to bring the heel up to the hip;
high-knee drills, which teaches how to lift the knee in
front of the body and drive the foot down to the ground;
A-drills, which combine ankling, heel-kick drills, and high-
knee drills; and B-drills, which combines A-drills with an
exaggerated knee lift to teach active foot recovery.
The drills described above are the most eff ective tech-
nique drills. Many of these drills begin at a walking pace,
focusing on one side of the body at a time, eventually pro-
gressing to a skip alternating between the left and right
sides. The challenge with technique drills is that they are
not a substitute for sprinting because they do not resem-
ble sprinting kinematically (3). In other words, the drills
need to be kept in perspective with a training program.
Explosive starts teach athletes how to take the fi rst step
explosively. This is an important skill because the more ex-
plosively an athlete can take the fi rst step, potentially the
faster they can arrive somewhere. Usually this is done over
a progression of starting positions; falling starts, stand-
ing starts, crouching starts, and eventually sport-specifi c
starts.
Learning to run fast is a skill; this means that it is critical
that it is practiced. With that in mind, athletes should per-
form sprints over various distances to learn how to run
fast and to improve performance.
Resisted sprinting makes the sprinting motion more diffi -
cult. This is done by adding weight to the athletes, having
them tow something, or running uphill. The idea is that
by making the motion more diffi cult by adding resistance,
athletes will have to recruit more muscle fi bers to perform
the sprint. Over time this can carry over to normal sprint-
ing, resulting in faster athletes. Care needs to be taken
with resisted sprinting as too much resistance will disrupt
running mechanics, teaching athletes to be slow and have
poor technique (4,5).
Assisted sprints help athletes to run faster than they are
normally capable of running. This is usually from some-
thing pulling the athletes, but can also be from a high-
speed treadmill or from running downhill. The idea is that
athletes will eventually learn how to move their limbs
faster, resulting in faster athletes. Care needs to be taken
with assisted sprints as having athletes run too fast can be
counterproductive as technique can break down.
nsca’s performance training journal • www.nsca-lift.org • volume 10 issue 4 12
Speed Development
Varied-pace sprints teach athletes to shift gears
and run at diff erent speeds. In many ways,
varied-pace sprints resemble the motions per-
formed by athletes on the fi eld. This can be a
very tiring type of exercise for athletes, which is
why these are not normally a beginner’s tool.
Speed is often expressed as the product of stride
frequency and stride length. The idea is that if
one (or both) can be increased, the athlete will
run faster. Stride length drills involve athletes
running at longer-than-normal strides. Stride
frequency drills help teach athletes to move
their limbs faster.
The exercises used for speed development
should change as athletes progress in their de-
velopment. As athletes progress through their
careers, they get closer to their genetic limita-
tions. This means that diff erent training tools
and diff erent approaches must be employed to
continue advancing their speed. It also needs to
be kept in perspective that at all levels an ath-
lete only has so much time to devote to training
and has limited physical resources for training.
In other words, training tools should be selected
based on which are the most benefi cial to the
athlete.
Beginning athletesFor the purposes of this article, beginners are
classifi ed as anyone that is not in college or
is not an elite athlete. This category includes
youth and high school athletes. With regards to
speed development, beginners have a number
of needs. First, they need to learn how to run
fast. Several things are involved in this such as
technique drills, learning to start explosively,
and practicing sprinting over various distances.
Second, they need to prepare their bodies to be
successful at speed training. This encompasses
a number of things such as strength training,
exercises to help prevent injuries, and limited
plyometrics.
Collegiate/National-Level athletesThis category of athletes refers to those that
compete on a national stage. In theory, they
have a training background and a strength and
conditioning foundation already established at
this level. With regards to speed development,
this level of athlete has four primary needs.
Their fi rst need is to continue learning how to
run fast. This means continuing to focus on tech-
nique drills, explosive starts, and sprints over
varied distances. The second need is that speed
needs to be applied to their given sport. Sport-
specifi c starting positions and sport/position-
specifi c sprint distances should be incorporated
at this level. The third need is the recognition
that at this stage a wider variety of speed train-
ing tools may be appropriate. The focus needs to
remain on sprinting to become better at sprint-
ing, but it is appropriate to begin introducing
some limited resisted/assisted sprinting and var-
ied pace exercises for variety. Finally, athletes at
this level need to continue preparing their bod-
ies to be successful at speed training. Athletes
are going to require more advanced strength
training to continue making them stronger and
more powerful. A real focus also needs to be put
on preventing hamstring and shin splint injuries
that may occur from speed training .
Professional/Elite athletesAthletes in this category train for a living, are
competing at the highest possible level, and are
very close to their genetic limits. These athletes
have a lifetime of training behind them, respond
to training as individuals, and have unique
needs. With regard to speed development, this
level of athlete has the following needs.
First, athletes at this level require individual-
ized programs based upon their strengths and
weaknesses. Elite athletes have extensive train-
ing experience, strengths, weaknesses, injuries,
preferences, and superstitions; this must be
accounted for in a training program. Second,
programs need to be specifi cally designed with
the sport and position in mind. Elite athletes are
unlikely to radically change positions or sports
at this stage in their career and will not benefi t
from “general” training. This means focusing the
programs around their needs. Third, the athletes
need to have access to almost all of the train-
ing tools used in speed training. Elite athletes
are near their genetic potential, this means they
need as much variety as they can get while ob-
serving specifi city. Finally, these athletes need to
continue preparing their bodies to be success-
ful at speed training. An injury at this level could
have signifi cant results to the athletes’ career,
fi nancial status, and the strength and condi-
tioning coach’s reputation. These athletes need
to continue performing strength training, plyo-
metrics, and exercises designed to address the
hamstrings and prevent shin splints.
Table 1 provides examples of how exercises
should change as athletes progress through
various levels of development. Note that this
table only focuses on those exercises to help
with speed development. As athletes progress
through their careers, the exercises available to
them expand.
Speed is an important ability for almost any ath-
lete and is assessed in most sports. While it is rec-
ognized that athletes are not sprinters, the fact
is that the faster an athlete is the faster they can
arrive somewhere. There are a number of tools
used to train athletes to run faster but not all of
them are equally relevant for every athlete at ev-
ery level. n

Whey Protein vs. Casein Protein
and Optimal RecoveryProtein supplements are invading grocery store aisles
and health food stores promising greater strength, faster
recovery time and bigger muscles. Is a supplement what
athletes need or can they get by with just a glass of milk?
The answer lies within the glass. When athletes eat, and
what ratio of carbohydrates to proteins they eat after a
workout can signifi cantly improve the recovery period af-
ter exercise (4).
Post-workout recommendationsTiming is everything, especially when it comes to what
athletes eat after engaging in strength and conditioning
training. Eating a combination of carbohydrates and pro-
tein within 30mins post-workout helps maximize muscle
synthesis, muscle function and decreases muscle break-
down. This occurs because this is the time that muscles ex-
perience a heightened sensitivity to insulin (4,7). Addition-
ally, consuming the right combination of carbohydrates to
protein, in a 4:1 ratio, is associated with faster glycogen
replenishment in the muscles, better muscle protein syn-
thesis, reduced muscle soreness and improved muscle
strength and body composition (2,4). Thus, the recipe for
optimal post-exercise recovery is taking advantage of the
30-min recovery window and choosing foods that portray
the 4:1 ratio of carbohydrates to protein. Chocolate milk
is a quick and easy post-recovery drink that naturally con-
tains carbohydrates and proteins in the correct ratio. See
Table 1 for other post-exercise snack options.
Whey vs. caseinCow’s milk is composed of carbohydrates and two main
dairy proteins: casein and whey. When milk is coagulated,
it automatically divides out the proteins into semi-solid
lumps and a liquid portion. Casein is found in the lumps,
or curds, whereas the whey protein is found in the liquid
portion (5). The ratio of protein within a glass of milk is
about 20% whey to 80% casein, which provides an opti-
mal composition of readily available nutrients to replenish
body fuel post-workout and keep energy levels up (5).
Whey is known as the “fast-acting” protein, meaning that
the body can break it down and absorb the nutrients
relatively quickly (1). In some cases, manufacturers break
down whey even further into whey protein isolate, whey
concentrate or whey powder, which are then sold in dif-
ferent forms as supplements. These lactose-free, concen-
trated protein supplements are absorbed at a quicker rate
than casein. Additionally, whey is high in indispensible
(essential), branched-chain amino acids that the body
cannot produce on its own and must derive from food (1).
This allows for quick uptake by the body (6). Some studies
have found that whey protein supplements may be asso-
ciated with an increase in muscle mass size and strength
in some individuals as well (7).
Casein, often referred to as the “slow-acting” protein, takes
slightly longer to digest as it slowly releases amino acids
into the bloodstream (6). It contains a diff erent amino acid
profi le than whey and is particularly high in the condition-
ally indispensible amino acid, glutamine (1). This is ben-
efi cial because, when the body is put under physiological
stress, such as with endurance exercise, the body needs to
derive glutamine from an outside source of food (1). The
bottom line, however, is that both whey and casein are
needed for proper nutrition.
Some supplements contain both whey and casein to al-
low the body to take full advantage of the diff erent ab-
sorption rates (1,8). Additionally, the combined eff orts are
benefi cial because whey works to stimulate protein syn-
thesis whereas casein inhibits the breakdown of protein
(9). Therefore, individual, isolated supplements of either
whey or casein may not be the best option.
Milk: Full or low-fat? Research shows that low-fat dairy is more eff ective at pro-
tein synthesis and replenishing net muscle protein bal-
ance than high-fat dairy (6). One theory is that the fat is
digested at a slower rate than carbohydrates and protein,
and thus the fat slows down the delivery of carbohydrates
and protein to tissues (6). Furthermore, chronic use of
training table
nsca’s performance training journal • www.nsca-lift.org • volume 10 issue 4 15
Whey Protein vs. Casein Protein
low-fat milk as a post-exercise resistance training meal has been associ-
ated with a greater reduction in overall body fat, increased muscle growth
and greater muscle mass maintenance than soy-based proteins (3,9). Table
1 lists whole-food examples of post-exercise snack options that provide
the optimal balance of carbohydrates to proteins. Eat these snacks within
30mins after completing an exercise session for optimal glycogen and pro-
tein uptake.
Bottom lineThe combination of whey and casein protein found in cow’s milk provides
reliable nutrition to restock glycogen stores, promote protein synthesis
and repair muscles while providing benefi cial nutrients such as calcium, vi-
tamin D and vitamin A (6). Whole foods, such as low-fat milk, can be equal-
ly eff ective, if not more eff ective than supplement drinks in restoring the
body to optimal performance levels and naturally provide all the essential
nutrients in a ratio the body needs (6). Choose whole foods that contain a
4:1 ratio of carbohydrates to protein and consume them within 30mins af-
ter exercise to support muscle recovery, strength and build muscle mass. n

To have success in most sports, an athlete must be able
to run fast and be able to quickly change directions. How-
ever, the forces generated in the hamstring muscle group
while running may cause a strain injury. A hamstring
strain injury may cause signifi cant pain and functional loss
(1,2,3,4). One injury mechanism occurs with an eccentric
hamstring muscle (lengthening) action, while the hips are
fl exed and knee extended, during the fi nal portion of the
swing phase. This is just one mechanism, however.
The time lost after a hamstring strain is as potentially long
as the time lost due to an anterior cruciate ligament sur-
gery of the knee. It has been reported that the average
return to sport time after a hamstring strain was 31 weeks
(4). In some cases, an athlete may be forced to retire due
to the severity of the injury and an inability to fully reha-
bilitate.
There are several injury risk factors for a hamstring strain
that have been identifi ed by sports medicine researchers.
Athletes at risk for injury should be assessed in the off -
season and pre-season by the athletic training staff and
prescribed exercises to correct for any muscular weakness
or infl exibility. Below is a list of common hamstring strain
risk factors (5,6):
• Muscular weakness
• Prior hamstring injury episodes
• Lack of fl exibility
• Poor muscular endurance capacity
• Poor, or lack of, warm-up prior to practice or compe-
tition
An athlete at risk of a hamstring strain should participate
in an off -season and/or pre-season training program to
help reduce the risk of sustaining a hamstring strain. A
recent trend is to address hamstring defi cits by having
an athlete perform eccentric exercises. Hamstring inju-
ries tend to occur during an eccentric lengthening of the
muscle. The inclusion of eccentric exercises is thought to
address an athlete’s strength defi cits in a functional man-
ner. In addition, eccentric exercises may help to improve
an athlete’s muscular infl exibility (2,3,4). Table 1 presents
a list of exercises that train the hamstrings eccentrically. n

Exercises to Reduce Hamstring Strains
Table 1. Eccentric Hamstring Exercises for Off -season or Pre-season Training Programs (2,3,4).
Exercise Technique
Inverted Hamstring The athlete balances on one leg with the knee in full extension. Next, the athlete should fl ex forward from the hip, not the back, maintaining a neutral spine position and stretching arms to the side to assist with balance. Hold each repetition for up to 30secs.
Romanian Deadlift Stand with feet shoulder-width apart, knees slightly bent. The athlete holds a pair of dumbbells or loaded barbell at mid-thigh level with arms fully extended. The athlete fl exes the torso forward and lowers the weight to mid-shin level. The focus should be on the hamstrings and gluteals and not the back.
Nordic (aka Russian) Hamstring Curl The athlete assumes a high kneeling pose on a padded surface. A strength coach should be positioned behind the athlete providing support/assistance by holding the ankles. The athlete then lowers their upper body as far as possible towards the fl oor then return to the upright position utilizing the hamstrings. Most will be unable to control their body all the way to the fl oor.
