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.
