5名健康男性受试者在环境温度36℃、相对湿度40%的条件下,以最大氧耗量40~50%的测力计上劳动1小时。测定其直肠温度、平均皮肤温度和热平衡的变化。实验分为两组:第1组,包含下列三种条件:缺水状态——劳动前24小时禁食禁水;不缺水状态——劳动前不禁水或即刻给以饮水810ml。第2组,分四种条件:缺水或每10分钟给1、13和37℃三种不
Five healthy male subjects were exposed to an dynamometer 40 to 50% of the maximum oxygen consumption for 1 hour under the conditions of an ambient temperature of 36 ° C and a relative humidity of 40%. The rectal temperature, the average skin temperature and the heat balance were measured. The experiment was divided into two groups: Group 1, containing the following three conditions: water shortage - fasting forbidden to drink for 24 hours before laboring; no water shortage - 810ml of drinking water can not be banished immediately before work. Group 2, divided into four conditions: lack of water or every 10 minutes to 1,13 and 37 ℃ three do not
