Metabolic ceiling as indicative of endurance capacity: 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. The thesis of limiting and determining factors of endurance consider variables such as maximum oxygen O 2 consumption VO 2maxmetabolic thresholds and movement economy the most importants.

The aim of this assay is to show that the incidence of fatigue in this kind of exercise might be related fosforjlao negative changes in mitochondrial oxidative potential. Mitochondrial oxidative potential is situated between the extreme limits of its functionality, which correspond to the states 4 rest and 3 VO 2max. The thesis put forward here is that when this variable is fosforilwo to the state 3 during prolonged intense exercise, the body depletes their possibilities to produce energy through oxidative elettrons, with consequent changes in metabolic thresholds and increase in the percent of VO 2max used in this condition.


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

Por outro lado, o destreinamento e o envelhecimento promovem queda na quantidade e funcionalidade mitocondrial. O oposto se aplica ao estado 3. Essa possibilidade foi parcialmente demonstrada recentemente 2. Esse fato foi parcialmente comprovado em moradores de grandes altitudes Tibetanos.
