8.18 T-Test

Test description

T-Test 

measures the subject’s ability to react, decelerate, 

change direction and re-accelerate to a given signal. The sub-
ject has six trials for each direction. The subject stands in front 
of the 

Powertimer Measurement Unit 

in ready position. The 

photocells are placed on each side of the mat at a given dis-
tance. The subject sprints through the first photocell to the 
jump mat. As the subject steps on the jump mat, the 

Powertim-

er Measurement Unit 

gives a directional signal. The subject 

takes off the jump mat and accelerates through the photocell.

Test parameters

T-Test

 has two parameters: 

Approach Distance 

from the first 

photocell to the jump mat and 

Acceleration Distance 

from the 

jump mat to the second photocell.

Test sequence

The test sequence is quite similar to the 

Take-off Reaction Test

It differs in that the subject starts the test by running through 
the first photocell instead of standing on the jump mat. When 
the subject steps on the jump mat, either the left or the right 
lamp is lit and the subject must run to the photocell at that di-
rection.

Test results

Approach Time

 is a new result; otherwise the results are the 

same as in 

Take-of Reaction Time Test

.

8.19 Throwing Gate Test (Throwing Gate)

Test description

The 

Throwing Gate Test 

measures the subject’s ability to pro-

duce explosive force in the upper body in overhead throwing 
action. The subject performs a predefined amount of throws 
with five different ball masses.

Test parameters

Throwing Gate Test

 has seven parameters: The 

Distance 

from 

the photocell to the jump mat or second photocell, the number 
of throws to be performed with each ball mass and the five 
different ball masses.

In training mode 

Throwing Gate

 test has one parameter: 

Dis-

tance

 between the first photocell and the second photocell or 

the jump mat.

Test sequence

The five ball masses were set in the test parameters, so before 
the test is started you need to select the correct mass for the 
first throw. The mass can be changed at any time by selecting 
the 

Change Weight 

action. When one ball mass has as many 

results as determined by the 

Number of Throws

 parameter, 

that mass is removed from the ball mass selector and you must 
choose a new ball mass for the next throw.

The ball can be thrown at either through two photocells or 
from one photocell to the jump mat. In either case there is a 
two-second timeout after each throw to prevent the start of a 
new measurement in case the ball bounces back through a 
photocell. If the ball misses the jump mat, the throw will be au-
tomatically cancelled after two seconds. However, if it misses 
the jump mat and bounces back through the photocell, it will 
create a test result, which you need to remove by selecting the 

Remove Result

 action. After the subject has performed the pre-

defined number of throws with each ball mass the test is com-
plete.

Throwing Gate

 can also be started in training mode. In train-

ing the best throwing velocity is used as the result base. The 
ball masses are ignored in the training mode. The subject tries 
to throw the ball at the speed calculated from the best test re-
sult.
