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 fosdorilao percent of VO 2max used in this condition.

Physiological responses during exercise to exhaustion at critical power.

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.

Dietary inorganic nitrate improves mitochondrial efficiency in humans. Therefore, mitochondria function as a cellular bioenergetic thermostat during situations such as those involving prolonged strenuous exercise. Mitochondrial oxidative potential is situated between the extreme limits of its functionality, which correspond to the states 4 rest and 3 VO 2max.
