8.10 Running-Based Anaerobic Sprint Test (RAST)

Test description
In Running-Based Anaerobic Sprint Test (RAST) the subject
sprints six 35-meter sprints with a 10-second recovery be-
tween the sprints. The test measures short-term anaerobic
sprint power.
Test parameters
Since the number of sprints and sprint distance is given in the
test description, RAST does not have any parameters that can
be changed.
Test sequence
The subject starts the test by doing the first sprint and the Per-
forming Test notification will be shown. After the subject has
done the first sprint and waited the 10-second recovery time,
the Measurement Unit will beep and the subject needs to
sprint back. After six sprints the test is complete.
Test results
The sprint times are measured and following results calculat-
ed:
• Power of each sprint in watts
• Relative Power
• Average Power of the sprints
• Velocity in meters per second
• Fatigue Index is the relation between the best and worst
jump powers

8.11 Reactivity / Stiffness Test (Reactivity-Stiffness)

Test description
The Reactivity / Stiffness Test is used to measure the explosive
strength and utilization of the elastic energy in the plantar flex-
ors. The subject begins the jumps outside the jump mat and
the first jump lands on the jump mat. She then continues jump-
ing on the mat until the pre-determined number of contacts
jumps is achieved.
Test parameters
The test has only one parameter: The number of jumps to be
performed in one test action.
Test sequence
The subject steps on the jump mat and starts jumping. Subject
then continues jumping until the predefined amount of jumps
has been performed. Note that Powertimer does not prevent
the subject from stopping, having a break and then continuing
the jumping.
Test results
Powertimer measures the jump and contact times and calcu-
lates following results:
• Jump Height in centimeters or inches depending on the re-
gional settings
• Jump Power for each jump in watts
• Relative Power for each jump in watts
