Therefore, mitochondria function as a cellular bioenergetic thermostat during situations such as those involving prolonged strenuous exercise. The aim of this assay is to show that the eletrins of fatigue in this kind of exercise might be related to negative changes in mitochondrial oxidative potential.

Increased substrate oxidation and mitochondrial uncoupling in skeletal muscle of endurance-trained individuals. Compared with other animal species, the endurance capacity of humans is remarkable. Higher mitochondrial respiration and uncoupling with reduced electron transport chain content in vivo in muscle of sedentary versus active subjects.

Mitochondrial oxidative potential is situated between the extreme limits of its functionality, which correspond to the states 4 oxxidativa and 3 VO 2max. Services on Demand Journal.

The thesis put forward here is that when this variable is close to the state 3 during prolonged intense exercise, transporrtadora 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.
