• Description:
  Ventilatory gas exchange ratio, ventilation, respiration rate, rectal temperature, heart rate, and oxygen uptake are determined for four acclimated subjects performing intermittent and prolonged exercise on a treadmill at 24 and 54 degrees centigrade. Respiration rate, heart rate, rectal temperature, and respiratory dead space are increased at the higher temperature. Ventilatory gas exchange ratio is higher in the initial cycles with lower values at the hot ambient condition, suggesting that heat is more effective than time in lowering the ventilatory gas exchange ratio, probably with greater dependence on fat oxidation in the latter exercise cycles which seemed to be more pronounced in the heat.
