Higher mitochondrial respiration and uncoupling with reduced electron transport chain content in vivo in muscle of sedentary versus active subjects. The aim of this assay is to transportasora that the incidence of fatigue in this kind of exercise might be related to negative changes in mitochondrial oxidative potential.

Exercise efficiency is reduced by mitochondrial uncoupling in the elderly. Tonkonogi M, Sahlin K. Why marathon migrants get away with high metabolic ceilings: Dietary inorganic nitrate improves mitochondrial efficiency in humans. Energy metabolism in contracting rat skeletal muscle: 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. Determinants of time trial performance and maximal incremental exercise in highly trained endurance athletes.

Therefore, mitochondria function as a cellular bioenergetic thermostat during situations such as those involving prolonged strenuous exercise. Natural selection for energetic efficiency and the relationship between activity level and mortality. Physiological responses during exercise to exhaustion at critical power.

Mitochondrial oxidative potential is situated between the extreme limits of its functionality, which correspond to the states 4 rest and 3 VO 2max. The J Exp Biol.

Mitochondrial oxygen affinity predicts basal metabolic rate in humans. Intrinsic and extrinsic uncoupling of oxidative phosphorylation. 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 oxidayiva energy through oxidative phosphorilation, with consequent changes in metabolic thresholds and increase in the percent of VO 2max used in this condition.

The maximum oxygen consumption and aerobic scope of birds and mammals: Mitochondrial uncoupling reduces exercise capacity despite several skeletal muscle metabolic adaptations. O oposto se aplica ao estado 3. A funcionalidade mitocondrial encontra-se situada entre limites extremos que correspondem aos estados 4 repouso e 3 VO 2max.

Por outro lado, o destreinamento e o envelhecimento promovem queda na quantidade e funcionalidade mitocondrial. Estudos recentes demonstraram em ratos que o desacoplamento mitocondrial induzido quimicamente com dinitrofenol resulta: Short-term training alters the control of mitochondrial respiration rate before maximal oxidative ATP synthesis.
