Fig. 7From: A survey of mathematical models of human performance using power and energyCritical power (CP) concept using Morton’s hydraulic vessel analogy [38]: Energy domains show sub-CP and supra-CP vessels connected by a tube of fixed diameter. Morton’s aerobic and anaerobic vessels are replaced by < CP and > CP respectively as the curvature constant (W′) and anaerobic work capacity (AWC) cannot be used interchangeablyBack to article page
