Heat induced fatigue and changes of the EEG is not related to reduced perfusion of the brain during prolonged exercise in humans

Research output: Contribution to journalJournal articleResearchpeer-review

(1) Exercise-induced hyperthermia is associated with a gradual slowing of the electroencephalogram (EEG), an increase in perceived exertion (RPE) and a lowering of the cerebral perfusion.

(2) During exercise EEG changes were linearly correlated to core temperature (r 2=0.67; P<0.05) and RPE (r 2 =0.54, P<0.05), but manipulation of cerebral perfusion by voluntary breathing efforts and by CO 2 inhalation did not alter RPE or EEG.

(3) In conclusion EEG changes with hyperthermic exercise are not a simple effect of the reduced cerebral perfusion but may relate to the fatigue that arises concomitantly with the increases in core and brain temperatures.
