The rate of sweat evaporation from the arm, chest, back and thigh, aural temperature, skin temperature (arm, chest, back and thigh), heat production (derived from measurements of respiratory gas exchange) and heart rate were measured in 7 men during 15 minutes of leg or arm cycling at 32% of predicted maximum oxygen uptake (VO2 max). The regional sweat evaporation rates and changes in body temperature were similar during both forms of exercise. The peak rates of sweat evaporation from the arm, chest, back and thigh were 15.7 +/- 19.8, 25.0 +/- 21.6, 28.7 +/- 22.7 and 21.0 +/- 18.2 mg.cm-2 hr-1 during leg cycling and 13.2 +/- 11.6, 22.2 +/- 14.4, 27.6 +/- 14.7 and 19.2 +/- 13.3 (SD) mg.cm-2 hr-1 respectively during arm cycling. The sweat evaporation rates from the different body regions were not significantly different from one another.
在7名男性以预计最大摄氧量（VO2 max）的32%进行15分钟腿部或手臂骑行运动期间，测量了手臂、胸部、背部和大腿的汗液蒸发速率、耳温、皮肤温度（手臂、胸部、背部和大腿）、产热（通过呼吸气体交换测量得出）以及心率。在两种运动形式中，局部汗液蒸发速率和体温变化相似。腿部骑行时，手臂、胸部、背部和大腿的汗液蒸发峰值速率分别为15.7 +/- 19.8、25.0 +/- 21.6、28.7 +/- 22.7和21.0 +/- 18.2毫克·平方厘米·小时-1；手臂骑行时，相应部位的汗液蒸发峰值速率分别为13.2 +/- 11.6、22.2 +/- 14.4、27.6 +/- 14.7和19.2 +/- 13.3（标准差）毫克·平方厘米·小时-1。不同身体部位的汗液蒸发速率彼此之间无显著差异。
