A Study of Behavioral Thermoregulatory Response and Body Temperature Change with Exercise

在这项研究中，我研究了体温调节行为反应，以探讨人类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，受试者在休息时选择舒适的环境温度，运动时选择热水暴露在腿下，发烧时选择流感条件。我测量了直肠温度，皮肤温度和环境温度。实验结束时选取的环境温度为发热>休息>运动>热暴露条件。运动强度越高，选择的环境温度越低。实验结束时的平均体温为发热>运动>休息=热暴露条件。从这些结果来看，运动中的体温调节设定点可能随着发烧而改变。为研究雌性大鼠日常运动后静息时体温水平的变化，采用热梯度测试方法，分别在每日自主轮跑运动后和运动前进行热梯度测试。轮子跑得越快，体温越高。在热梯度试验中，大鼠在每日轮跑活动后选择较高的环境温度，体温保持较高水平。从这些结果可以看出，休息时的热疗与日常运动是调节体温变化的。

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.
