The aim of this study was to compare the efficiency of exercise thermoregulatory functions in Thai and Polish groups. Twelve Thai and 14 Polish healthy male students were included. An exercise test on a bicycle ergometer at 53% of the maximal work load was performed at ambient air temperature of 30 degrees C and relative humidity of 70%. The test was terminated when rectal temperature (Tre) rose by 1.2 degrees C. Duration of this exercise considered as an index of the efficiency of exercise thermoregulatory functions. The duration of test exercise was evidently longer in Thais (44.8 min) than in Polish students (34.1 min). The rate of increase in the internal body temperature was lower in Thais (0.029 degrees C x min-1) than in Poles (0.037 degrees C x min-1) but exercise dehydration as well as the rate of body weight loss were significantly higher in Thais than in Poles. It can be concluded that the exercise thermoregulatory mechanisms are more efficient in Thais. Polish young athletes were poorly adapted to exercise in warm and humid environment and thus they require more exercise training in climatic chamber prior to competitions held in countries with warm and humid climate.
本研究的目的是比较泰国人和波兰人群体运动体温调节功能的效率。纳入了12名泰国健康男学生和14名波兰健康男学生。在环境空气温度为30摄氏度、相对湿度为70%的条件下，在自行车测力计上以最大工作量的53%进行运动测试。当直肠温度（Tre）上升1.2摄氏度时，测试终止。本次运动的持续时间被视为运动体温调节功能效率的指标。泰国人的测试运动持续时间（44.8分钟）明显长于波兰学生（34.1分钟）。泰国人身体内部温度的上升速率（0.029摄氏度×分钟-1）低于波兰人（0.037摄氏度×分钟-1），但泰国人的运动脱水以及体重减轻速率显著高于波兰人。可以得出结论，泰国人的运动体温调节机制更有效。波兰年轻运动员对在温暖潮湿环境中的运动适应不佳，因此在温暖潮湿气候国家举行比赛之前，他们需要在气候室进行更多的运动训练。
