| Outline of Final Research Achievements |
Hyperthermia during exercise leads to increases in minute ventilation independently of metabolic factors, resulting in hypocapnia and cerebral hypoperfusion. This study examined the effect of time of day on respiratory and cerebrovascular responses during prolonged exercise in the heat. We showed that ventilation, estimated arterial CO2 pressure and middle cerebral artery blood velocity during prolonged exercise in the heat did not differ between morning and evening. These results suggest that time of day has no effect on the time course of hyperventilation, PaCO2 and cerebral blood flow response during prolonged exercise in the heat.
