Abstract

Involvement of the brain in endurance exercise regulation is not a particularly new concept. Although exercise termination has been proposed to occur when generation of the required power output is no longer possible because of failure at sites within the musculature (1), there is growing evidence that there is a neural component to our ability to tolerate sensations of fatigue and that exercise termination includes a psychological element (23). This involves afferent feedback of the disturbances in homeostasis at the musculature and cardiopulmonary systems to the brain (23), where these signals are interpreted. That the motor cortex (MC) is not activated maximally at exercise termination suggests that regions upstream of the MC provide such input into how we interpret these signals and when we terminate exercise.
