| Outline of Final Research Achievements |
Elevations in body temperature at rest and during exercise lead to increase in ventilation, which can reduce arterial CO2 pressure (PaCO2) and, in turn, cerebral blood flow (CBF) and thermoregulatory response. We investigated 1) whether humans can voluntarily suppress hyperthermic hyperventilation during prolonged exercise and passive heating at rest, and 2) the effects of voluntary breathing control on PaCO2, CBF, sweating and skin blood flow. Our results indicated that during prolonged exercisein the heat and passive heating at rest, humans can voluntarily suppress hyperthermic hyperventilation, and this suppression mitigates changes in PaCO2 and CBF.
