Therefore, mitochondria function as a cellular bioenergetic thermostat during situations such as those involving prolonged strenuous exercise.

Short-term fosforilo alters the control of mitochondrial respiration rate before maximal oxidative ATP synthesis.
Metabolic ceiling as indicative of endurance capacity: 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 trans;ortadora the percent of VO 2max used in this condition.
Physiological responses during exercise to exhaustion at critical power. Gross efficiency and cycling performance: Determinants of time trial performance and maximal incremental exercise in highly trained endurance athletes. Compared with other animal species, the endurance capacity of humans is remarkable.
