高湿热锻炼的生理特征和习服效果评价

The physiological feature and evaluation of acclimatized effect of training in intense heat and moisture environment

12名健康男青年分为两组,A组(6人)锻炼环境热强度和直肠温度较高,B组(6人)较低。受试者于人工气候室内进行高湿热锻炼,连续10天,两组每天平均锻炼时间分别为59.8min和52.6min,平均直肠温度达38.71℃和38.32℃,生理紧张指数为3.5和3.0。锻炼周期前,后的标准试验自身对比表明,实验室的高湿热锻炼如同部队现场一样,都提高了机体热负荷的耐受能力,但A组高于B组。

Twelve healthy young males were averaged into 2 groups ( n=6 ) : Parameters in environmental heat strain of training and rectal temperature after heat were greater in group A than in group B. All subjects tested were asked to perform a tra-ining of intense moist heat in a hot chamber once daily for 10 consecutive days. The mean exercise time per day of the both groups was 59.8 min and 52.6 min, the mean rectal temperature after training reached 38.71℃ and 38.32℃, and PSI was 3.5 and 3.0 respectively. The auto-control in the standard tests before and after the training showed that the intense moist heat training in the laboratory could improve the heat tolerance capability just as the spot training of troops could. The improvement was more remarkable in group A than in group B.
