Recently, lots of experiments have verified the effect of central nervous system (CNS) on fatigue, cerebral metabolic and neurohumoral alterations during strenuous exercise may result in the impairment of cortex activity, and this may lead to the failure of CNS sustaining adequate central drive to spinal motoneurons (Davis and Bailey, 1997).
