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.
