项目摘要

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.

在本研究中，我研究了体温调节行为反应，以探讨人体运动和大鼠日常运动时体温升高的机制。在人体运动时体温变化的研究中，受试者选择了休息时舒适的环境温度、运动、腿部热水暴露和流感发热条件。我测量了直肠温度，皮肤温度和环境温度。各实验结束时选择的环境温度为发热>休息>运动>热暴露条件。运动强度越高，选择的环境温度就越低。各实验结束时的平均体温为发热>运动>休息=热暴露条件。这些结果表明，运动过程中的体温调节设定点可能会随着发烧而发生变化。在雌性大鼠日常运动安静时体温水平变化的研究中，在每日自愿跑轮运动后或运动前进行了热梯度测试。车轮跑活动越高，体温越高。在热梯度实验中，大鼠在每天跑轮活动后选择较高的环境温度，体温保持在较高水平。从这些结果可以看出，在休息时的体温过高与日常运动是受调节的体温变化。
