Abstract

Two fit subjects performed two cycle-ergometer exercise bouts, one of 200 W for 48 min with a following 12-min recovery phase and one of 250 W for 30 min with a subsequent 15-min monitored recovery period. Experiments were performed in ambient conditions of 18 +/- 1 degrees C, 52% relative humidity +/- 5% and 0.5 m.s-1 + 0.5 air velocity (mean +/- range). Experimental values obtained from rectal and tympanic temperature sites were compared with simulation figures produced from a FORTRAN model of human thermoregulation. Data obtained provide qualified experimental support for the concept of a simple feedback model to simulate human core temperature during exercise in ambient temperatures below 20 degrees C.

摘要

两名健康受试者进行了两次自行车测力计运动试验，一次以200瓦的功率持续48分钟，随后有12分钟的恢复阶段；另一次以250瓦的功率持续30分钟，随后有15分钟的监测恢复期。实验在环境温度为18±1摄氏度、相对湿度为52%±5%、风速为0.5米/秒±0.5（平均值±范围）的条件下进行。将从直肠和鼓膜温度测量点获得的实验值与人类体温调节的FORTRAN模型产生的模拟数据进行比较。所获得的数据为一个简单反馈模型的概念提供了合格的实验支持，该模型用于模拟环境温度低于20摄氏度时运动期间的人体核心温度。
