Why peak power is higher at the end of steeper ramps: an explanation based on the "critical power" concept.

Experimental studies have consistently reported higher peak power outputs at the termination of steeper ramp exercises. One explanation can be deduced from oxygen uptake kinetics. This short communication offers an alternative explanation based on the "critical power" concept of human bioenergetics. Algebraic, calculus, and geometric aspects of this explanation are all detailed, and it is illustrated with data from a previous study.
