The thesis put forward here is that when this variable is close to the state 3 during prolonged intense exercise, the body depletes their possibilities to produce energy through oxidative phosphorilation, with consequent changes in metabolic thresholds and increase in the percent of VO 2max used in this condition.

Energy-limited tolerance to stress as a conceptual framework to integrate the effects of multiple stressors. Mitochondrial oxidative potential is situated between the extreme limits of its functionality, which correspond to the states 4 rest and 3 VO 2max.

Mitochondrial oxygen affinity predicts basal metabolic rate in humans. The aim of this assay is to show that the incidence of fatigue in this kind of exercise might be related to negative changes in mitochondrial oxidative potential.
