Arterial oxygenation, central motor output and exercise performance in humans

摘要

The studies of Amann et al. (2006, 2007) conclude that feedback from fatiguing skeletal muscle during exercise at different F_(IO2) reduces central motor output to the working muscles "in order to reinvent excessive development of peripheral muscle fatigue beyond a critical threshold or sensory tolerance limit" (Amann etal. 2006, p. 950). We suggest that their findings can be better explained by hypoxia-induced changes in central motor output acting in an anticipatory manner
