“…Even though it has been stated that central fatigue coincides with the attainment of fixed high body and brain temperatures (Fuller et al, 1998;Gonzalez-Alonso et al, 1999;Nielsen et al, 1993;Walters et al, 2000), there is evidence that dynamic mechanisms are consistent regulators of feelings of fatigue. In support of this hypothesis, the rates of heat storage and body heating that are associated with changes in neurotransmitter content in thermoregulatory centers emerge as important factors in determining fatigue Hasegawa et al, 2008;Lacerda et al, 2005Lacerda et al, , 2006Leite et al, 2006, L.
