Severe heat stress experienced by aircrew during summer months can cause deterioration in performance. Acute heat stress can also lead to dehydration and loss of electrolytes. Previous studies emphasised the need of K+ replacement. This study was carried out to determine the effect of glucose electrolyte ingestion (ELECTRAL) on thermal strain parameters. Ten healthy male subjects in the age group of 19-43 years were exposed to an acute thermal environment of 50 degrees C Tdb with relative humidity of 30% for 40 min. twice each day on two different days with an interval of one hour in between the exposures. At the beginning of rest period electrolyte solution was ingested during electrolyte trials and water under control trials. Physiological parameters of Tsk, T or, HR and electrolyte concentration of Na+ and K+ in sweat did not show any significant difference in both the trials. Sweat loss was significantly higher during electrolyte trials.
夏季飞行人员所经历的严重热应激会导致工作表现下降。急性热应激还会导致脱水和电解质流失。先前的研究强调了补充钾的必要性。本研究旨在确定摄入葡萄糖电解质（口服补液盐）对热应激参数的影响。10名年龄在19至43岁之间的健康男性受试者，暴露于干球温度50摄氏度、相对湿度30%的急性热环境中40分钟，在两天内每天进行两次，两次暴露之间间隔一小时。在休息期开始时，在电解质试验期间摄入电解质溶液，在对照试验期间摄入水。在两项试验中，皮肤温度、口腔温度、心率以及汗液中钠和钾的电解质浓度等生理参数均未显示出任何显著差异。在电解质试验期间，汗液流失显著更高。
