The 5 talent identification areas that are
important for a sprinter are:
1. Acceleration Potential
2. Maximum Velocity Capabilities
3. Anthropometry
4. Psychological Performance
5. Strength/Power Levels
|
Each of the above areas, with
protocol included, could be tested via the following:
|
1.
Acceleration Potential
|
A. Timed 30
metres run with split times at 10 metres and 20 metres.
Athlete starts 30 cm back from first timing light and runs as fast as possible
through the set of lights. Testing to be done on an athletics track, in running
shoes, not spikes, with 3 trials available to record the fastest possible time.
Recovery between each trial will be a minimum of 3 minutes.
B. Vertical Jump
Stand and reach test, with chalk on hands. Athlete is allowed counter movement
downward with legs as well as arm swing but must start from a stationary
position (no walk in). 3 trials are allowed with a minimum of 60 seconds
recovery.
C. 5 Bunny (2 footed) Jumps
Athlete undertakes test on athletics track. Stationary start with toes on a
line. 5 continuous jumps are attempted. Distance obtained is where the heel of
the fifth landing occurs. 3 trials are allowed with a minimum of 2 minutes
recovery.
|
| 2. Maximum Velocity
Capabilities |
A. Flying 30 metre time from a 30 metre run in.
Test to be undertaken on athletics track (not grass). Athlete runs for 30metres
to build up speed, then tries to run through the 30 metre zone as fast as
possible. 3 trials are given to record the fastest possible time. Recovery
between trials of 3 minutes minimum.
B. Drop Jump
Athlete stands on a 30 cm high box. They drop off the box, not jump off, and
then when they land on the ground they try and jump as high as possible. 3
trials are given with the highest height the athlete achieves being recorded.
Test to be done in athletic shoes.
|
| 3. Anthropometry |
A. Calf Circumference/Height
Athlete’s calf circumference is measured on both legs, with the widest point
being recorded, as well as their height, without shoes.
B. Ankle Circumference/Height
Athlete’s ankle circumference is measured on both legs, with the widest point
being recorded, as well as their height, without shoes. For convenience, the
ankle will be taken to be directly at the top of the where the athlete’s shoes
sit on their foot.
|
4. Psychological Performance
|
A test to establish how the athlete reacts to stress,
pressure, how inwardly
strong they are etc.
|
| 5. Strength/Power Levels |
A. Seated 2kg throw
Athlete sits on floor, with back against a wall and chest passes the medicine
ball as far as possible. No rocking backward or forward. 3 trials are given
with the best distance recorded.
B. Forward Shot Throw
Athlete takes a 4kg shot and throws it forward as far as possible. Athlete
swings shot between legs and is allowed forward movement as they let the shot
go. 3 trials are given with the furthest distance recorded. Distance measured
from the front of the athletes foot to the point where the shot breaks the
ground closest to the athlete.

Justification for each test:
|
| |
| 1. Acceleration Potential |
A. Timed 30 metres run with split times at 10 metres and 20 metres.
To see how good a sprinter an athlete might be they need to be tested
sprinting! To be able to perform at the highest level the athlete needs to
accelerate quickly so this is a very specific and suitable test. Intermediate
times are taken for extra information to see if the athlete accelerates very
quickly and then slows down or if they can keep on accelerating.
B. Vertical Jump
Vertical jump requires high degrees of force put into the floor with great
speed, and this is what is required to be able to accelerate the body quickly
when sprinting. It is well accepted that those athletes who can achieve good
scores on vertical jump performance will be able to accelerate well too.
Similar muscle groups are also used in this test (compared with the muscle
groups used in acceleration), namely the quads and glutes, so this is further
support of this test.
C. 5 Bunny (2 footed) Jumps
As the previous test was vertical in nature, another test can be performed that
is horizontal. Sprinting does require strength in both planes (vertical and
horizontal) so this test is useful. This test also requires some hip extension
which is very important in sprinting.
|
| 2. Maximum Velocity
Capabilities |
A. Flying 30 metre time from a 30 metre run in.
Athletes who have the highest velocity are often the most successful,
therefore a test to find if an athlete can reach high velocities is very
important.
The 30 metre flying test is a standard test to measure an athletes maximum
velocity and ability to hold it.
B. Drop Jump
The drop jump test is used to test the athlete’s ability to hit the ground and
absorb force then produce force very quickly, as is needed when the athlete is
sprinting. If the athlete cannot produce force quickly then they will have a
long
ground contact time and probably not be a very successful sprinter.
|
3. Anthropometry
|
|
A. Calf
Circumference/Height B.
Ankle Circumference/Height
|
Athletes who have a large mass in the lower leg will be negatively effected by
this, in that it will reduce their ability to reach higher velocities, as the
larger
mass below the knee reduces the velocity that the lower leg can swing about
the knee which in turn decreases the velocity the sprinter can reach (as the
velocity is a product of stride length and stride frequency).
|
| 4. Psychological Performance |
The athlete needs to be able to deal with pressure in the environment of
sprinting and not choke. They also need to have the resilience to be able to
train hard for long periods of time and not give up. It is very important, in
my
opinion, for an athlete to be mentally tough if they are going to be successful
in the long term.
|
| 5. Strength/Power Levels |
|
A. Seated 2kg
throw B.
Forward Shot Throw
|
A standard test of upper body strength and perhaps a good indicator of fibre
type. If the athlete can throw the ball quickly, it will probably go a long way
and it may also indicate that they may have a dominance of fast twitch fibres
which are very desirable for sprinting.

I believe these tests can be
done with the athlete when they are around 12-14 years of age.
It needs to be taken into account the maturational age of the athlete as
different degrees of
maturation are going to lead to huge variations in performance and the athlete
who matures
early may not always be the star later in life.
The scores needed on these test are very difficult to predict and are going to
depend
enormously on the population you are dealing with as well as the maturational
age of the
athlete. For example a group of black American children are going to give far
different scores to white New Zealand children.
Having said that the ball park scores that I would might expect, but these are
very open, in
tests 1, 2 and 5 (with a 13 year old male) are: |

| There are of course going to
be a huge variety of scores with older and younger athletes and also female
athletes from the scores represented above. |
