本实验观察了高湿热环境热习服锻炼对人体汗液中矿物盐、氨基酸和维生素流失的影响。受试者为12名健康战士,锻炼方式为穿全身式防毒装具,于热气候室内以时速5.4km速度步行至自觉疲乏为止,连续10天,每天锻炼时间平均56.2min,平均直肠温度达38.5℃。标准试验对比证明,高湿热锻炼明显提高了人体热负荷的耐受能力。汗液中电解质浓度仅zn增高13.6%,K、Ca、Mg、Cu、Fe、Na有不同程度的降低,血清K、Na、Zn也降低。汗液中氨基酸除苯丙胺酸、蛋氨酸和胱氨酸下降较少外,其它14种氨基酸都明显降低。维生素B_1、B_2减少一半以上,维生素C减少35.5%。综上所述,热习服后可以大大减少汗液中营养成分的流失。
In this experiment, we observed the effects of hot, humid, hot, ambient acclimatization exercises on mineral salts, amino acids and vitamins in human sweat. The subjects were 12 healthy fighters, wearing a full body style of protective gear and walking in a hot climate at a speed of 5.4km / h until they were exhausted. For 10 consecutive days, the exercise time averaged 56.2 minutes per day and the average rectal temperature reached 38.5 ° C . Standard test comparison proved that high-heat hot exercise significantly increased the body’s heat load tolerance. The concentration of electrolytes in sweat was only increased by 13.6%, while the levels of K, Ca, Mg, Cu, Fe and Na were decreased, while the levels of K, Na and Zn in serum were also decreased. The amino acids in sweat except phenylalanine, methionine and cystine decreased less, the other 14 kinds of amino acids were significantly lower. Vitamin B_1, B_2 reduced by more than half, vitamin C decreased by 35.5%. In summary, the heat after the service can greatly reduce the loss of nutrients in sweat.
