- The central governor is a proposed process in the brain that regulates exercise in regard to a neurally calculated safe exertion by the body. In particular, physical activity is controlled so that its intensity cannot threaten the body’s homeostasis by causing anoxic damage to the heart muscle. The central governor limits exercise by reducing the neural recruitment of muscle fibers. This reduced recruitment causes the sensation of fatigue. The existence of a central governor was suggested to explain fatigue after prolonged strenuous exercise in long-distance running and other endurance sports, but its ideas could also apply to other causes of exertion-induced fatigue. The existence of a central governor was proposed by Tim Noakes in 1997, but a similar idea was suggested in 1924 by Archibald Hill. In contrast to this idea is the one that fatigue is due to peripheral "limitation" or "catastrophe." In this view, regulation by fatigue occurs as a consequence of a failure of homeostasis directly in muscles. (en)
