Abstract:

In order to study the difference of the local insensible perspiration rate in different test states, the error analysis was carried out on the equipment, and two equations were established separately to predict the error. And then, the local insensible perspiration rate was measured on the ambient temperature of 13 ℃ and  relative humidity of 35% under the three active state (sitting, standing and low speed walking at 2 km/h) of the back, waist, chest, tummy, hip, front thigh, rear thigh, leg, upper arm, lower arm. Finally, the local insensible perspiration rate and the total perspiration rate was compared. The results proved that no significant difference exists in the insensible perspiration among the three sports states as well as the total perspiration rate. The total sweat rate of standing state is 6.99% highest than that in the sitting state and the total sweat rate of walking state is 8.56% higher than in the sitting state. The paired t test shows a significant difference in the relative perspiration rate radio among the three states.
