Description

To study the mechanism for a rise in body temperature during exercise, the high protein-diet was given to human subjects. Ten healthy young women participated in this study. The subjects exercised at 60% V.O2max with a cycle ergometer for 60 minutes with fasting and meal conditions. Body temperature was higher in meal condition than in fasting condition before the exercise began (P<0.01). On the other hand, body temperature during exercise was raised with maintaining the difference before the exercise began. Heat production was significantly higher in meal condition than in fasting condition (P<0.01), but evaporative heat dissipation was not statistically significant. These results suggested that body temperature rise by DIT was never modified during exercise at 60% V.O2max and heat balance was kept. In other words, thermoregulatory response of the present experiments showed the passive responses that change in body temperature by DIT was superimosed on the change by exercise.<br>
