| Research Abstract |
In this study, I studied thermoregulatory behavioral responses to investigate the mechanisms of body temperature rise during exercise in man and with daily exercise in rats.
In the study of change in body temperature during exercise in man, the subjects selected comfortable ambient temperature during rest, exercise, hot water exposure under the leg and fever with influenza conditions. I measured the rectal temperature, skin temperatures and the ambient temperature. The selected ambient temperature at the end of each experiment was fever > rest > exercise > heat exposure conditions. The higher the exercise intensity, the lower selected ambient temperature. The mean body temperature at the end of each experiment was fever > exercise > rest = heat exposure conditions. From these results, it is suggested that thermoregulatory set-point during exercise may be shifted as a fever.
In the study of change in body temperature level at rest with daily exercise in female rats, thermal gradient test was performed after or before daily voluntary wheel running exercise. The higher the wheel running activity, the higher the body temperature. At thermal gradient test, the rats selected higher ambient temperature after daily wheel running activity and the body temperature was kept higher level. From these results, it is suggested that hyperthermia at rest with daily exercise is regulated body temperature change.
