Energetics of sinusoidal exercise below and across critical power and the effects of fatigue

ConclusionThe lower aerobic component during CPex than CP-50ex associated with lactate accumulation explained lower\({\dot{V}}_{{{\text{O}}}_{2}}\) AMP in CPex. The asymmetries in CPex suggest progressive decline of muscle phosphocreatine concentration, leading to fatigue, as witnessed by RPE.
