TANAKA, H., Selected Comfortabke Ambient Temperature during Rest, Exercise, Heat Immersion and Fever in Man. Abv. Exerc. Sports Physiol., Vol.8, No.1 pp.1-4, 2002. To investigate the mechanism of body temperature rise during exercise in man, I examined the behavioral thermoregulatory response by selected thermal comfortable ambient temperature (Ta) during conditions of rest, exercise of three intensities, heat immersion and fever (patients with influenza). The duration of eachi experiment was 60min for resting, exercise, and heat immersion conditions and 50min for fever conditions. The rectal temperature at the end of each experiment was higher after exercise (37.7℃, 38.1℃ and 38.4℃ at the three intensities, respecively), heat immersion (37.7℃) and fever (38.0℃) conditions than in the resting condition. Although the subjects selected a higher Ta in fecer condition and a lower Ta during exercise and heat immersion conditions than at rest, the mean body temperature, which was regarded as a total index of thermal information for body temperature regulation, was higher under exercise and fever conditions than in the resting or hear immersion conditions. The results suggest that the mechanism of body temperature change during exercise may be due to the shift of thermoregulatory set-point.
