不同环境温度和活动强度下人体出汗率测定

提出了一种测定人体出汗量的方法—衣物增重法,并利用该法分别测定20、25、28℃环境温度下,8名受试者在跑步机上分别以2、4、6mi/h(54、107、161 m/min)的速度跑步15min后的出汗量。运用配对样本t检验,并对出汗率测定结果进行分析后发现,环境温度和活动强度对人体单位面积出汗率均有显著影响,环境温度分别为20、25、28℃以及活动强度分别为2、4、6mi/h时,人体单位面积出汗率的范围为1.605～681.100 g/(h.m2)。

The Measurement of Sweat Rate under Different Ambient Temperature and Activity Intensity

A new method which was called clothing weight gain was put forward for measuring the amount of sweat produced by human body. With this method the amount of sweat produced by human body was measured after 8 subjects ran on a treadmill for 15 min at speeds of 2,4,6mi/b （54, 107, 161 m/rain） and in the ambient temperature of 20, 25, 28℃ respectively. By carrying out paired-samples t test, the measurement results of sweat rate were analyzed. It was found that both ambient temperature and activity intensity had significant effects on sweat rate per unit area. When the ambient temperature was 20, 25, 28 ℃ and activity intensity was 2, 4, 6mi/h respectively, the sweat rate per unit area was in the range of 1.605-681.100 g/（h· m^2） .
