8.3 Ajax Shuttle
Test description
The
Ajax Shuttle
measures the subject’s ability to accelerate,
stop, change direction and then re-accelerate. This test is a
slalom course in which the total sprint time is measured.
Test parameters
The test has only one test parameter: The number of sprints to
be performed in one test action.
Test sequence
The subject sprints through the track from the first photocell to
the second and
Powertimer SW-300
measures the total time.
While the subject is sprinting, the
Performing Test
notification
will be visible.
Test results
The Powertimer measures the sprint times
8.4 Contact Times
Test description
The
Contact Times
test measures the contact time of the foot
on the jump mat.
Test parameters
Contact Times
test has one test parameter: The number of con-
tacts to be performed within a test action.
Test sequence
The subject runs over the jump mat and the system measures
the contact and flight times. After the subject exits the jump
mat, the
Powertimer SW-300
will show a
Too long jump
notifi-
cation. This is normal behavior, since
Powertimer
assumes that
the subject is going to land on the jump mat. To create more
results, the subject just sprints over the jump mat again until
the predefined amount of results have been obtained.
The
Contact Times
test can also be started in training mode. In
training the best contact time from the actual testing is used as
the base result and the subject must try to obtain contacts that
are as close as possible to the calculated training result.
Con-
tact Times
training has no parameters.
Test results
The time of the foot on the jump mat and the time difference to
the next contact (flight time) is measured.
Results of
Contact Times
are not synchronized to the
Powertim-
er Analyzer
8.5 Counter Movement Jump (Counter Move Jump)
Test description
The
Counter Movement Jump
(CMJ) is used to test and meas-
ure speed and explosive strength performance. In CMJ the
subject jumps as high as possible on the jump mat. CMJ dif-
fers from
Static Jump
in that the subject makes a counter move-
ment before the actual jump.
Test parameters
CMJ has one test parameter: The number of jumps to be per-
formed in a test action.
