Questions

How is power worked out in RAST?

Power for each sprint = body weight x 35 x 35 / time cubed. The main result is the average power of all six sprints.

Why do I need body weight?

Power depends on body weight, so weigh the athlete before the test.

What is the fatigue index?

It shows how much power drops from the best sprint to the worst one.
