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 elerons metabolic thresholds and increase in the percent of VO 2max used in this condition.

A funcionalidade mitocondrial encontra-se situada entre limites extremos que correspondem aos estados 4 repouso e 3 VO 2max. Compared with other animal species, the endurance capacity of humans is remarkable.
