Redefining Fatigue: considerations for the calculation of critical power

Humans have a finite capacity for hard exercise. Sports scientists can mathematically determine this capacity by using multiple tests to exhaustion at different exercise intensities and looking at the relationship. However, the current testing protocols assume that once the initial point of fatigue is reached, exercise must be stopped. In the proposed study, we aim to quantify the ability of an athlete to perform work after reaching that initial point of fatigue by gradually decreasing the work rate.
