摘　　要：目的　对加速机体热习服锻炼方法的效果进行评价。方法　２０ 名健康战士分为实验组（１２ 名） 和对照组（８ 名） 。实验在热区５ 月中旬 （ 气温２５ ～３２ ℃） 进行。受试者每天下午穿军用雨衣在运动场上活动１２０ ｍｉｎ ， 连续锻炼１１ 天。其中第１ 、第６ 和第１１ 天在人工热室内进行定量热负荷试验， 试验中每３０ｍｉｎ 测定并记录心率、肛温和出汗量各一次。结果（１） 受试者锻炼第６ 天与第１ 天的结果比较体温明显降低； 第１１ 天与第１ 天比较， 其差别非常显著（ Ｐ＜ ０－０１） 。（２） 实验组在锻炼的第１ 、第６ 和第１１ 天， 心率逐渐下降， 分别与第１ 天相比， Ｐ 值均小于０－０５ ， （３）锻炼至第１１ 天， 当受热１２０ｍｉｎ 后， 两组的出汗总量分别为１－３９５ 和１－０８３ｋｇ （ Ｐ＜ ０－０５） 。实验组第１ 、２ 小时的出汗量分别为０－８８２ 和０－５１３ｋｇ （ Ｐ＜ ０－０５） ； 而对照组的变化无明显差别。结论　上述方法在加速机体热习服方面效果明显。Objective To evaluate the effect of exercising method to accelerate body heat acclimatization.Mothed 20 healthy male soldiers were divided into test group(12) and control group(8),experiments were done in middle May(Ta 25～32℃).The subjects of test group exercised on the playground in uniform raincoat for 120min every afternoon,lasted for 11 days;meanwhile,standard heat load test was also conducted in an artificial heated room on the first day,6th day and 11th day of the experiment.Heart rate(HR),rectal temperature(Tr)and sweat amount were measured every 30min during the experiment.Results (1)the body temperature of the 6th day and the 11th day after they endured heat 120min under the same thermal enviroment compared with results of the 1st days were greatly lowered especially the later(P<0 01);(2)after enduring heat load 120min,the reduce of heart rate at the 1st,6th and 11th was significant(P<0 05)in test groups;(3)on the 11th day,after 120min heat load,the sweat amount were 1 395 and 1 083kg respectively(P<0 05)in test and control group;the sweat amounts in the first hour and second hour were 0 882 and 0 513 kg in the test group(P<0 05),but there was no marked difference in control group.Conclusion The method mentional above shows obviors effect in accelerating body heat acclimatization.
