Why does the ATP-PC system provide the most ATP for muscle movement during the high jump?
It has a very rapid rate of ATP release for the explosive movement
It causes the least fatigue for the explosive jump
It has the highest yield of ATP to maximise the explosive power for the jump
It provides sustained energy throughout the jumping rounds
