For determination of the endurance limit range, 8 healthy male probands aged between 20 and 26 years loads had carried out for one hour on a bicycle ergometer at an ambient temperature of +20 degrees C, +28 degrees C and +35 degrees C. Staying in an ambient temperature of 35 degrees C leads to a decrease in the physical endurance limit in an order of magnitude of 10 W. At 20 degrees C, in the endurance range the following values result (mean +/- s): load 68+/- 10.3 W, heart rate 113.6 +/- 5.8 beats per min., net heart rate 31.8 +/- 2.4 beats per min., oxygen uptake 1340 +/- 170 ml per min., auditory canal temperature 36.5 +/- 0.24 degrees C, sweat rate 275 +/- 143 g. At 35 degrees C, the endurance limit is attained at the following values: 57 +/- 10.6 W, heart rate 125 +/- 11.8 beats per min., net heart rate 27.4 +/- 3.6 beats per min., oxygen uptake 1210 +/- 130 ml per min., auditory canal temperature 37.2 +/- 0.3 degrees C, sweat rate 577 +/- 96 g.
为确定耐力极限范围，对8名年龄在20至26岁之间的健康男性受试者在环境温度为+20摄氏度、+28摄氏度和+35摄氏度的条件下，于自行车测力计上进行了1小时的负荷测试。处于35摄氏度的环境温度会导致身体耐力极限下降一个数量级，即10瓦。在20摄氏度时，耐力范围内得出以下数值（平均值±标准差）：负荷68±10.3瓦，心率113.6±5.8次/分钟，净心率31.8±2.4次/分钟，摄氧量1340±170毫升/分钟，耳道温度36.5±0.24摄氏度，出汗率275±143克。在35摄氏度时，耐力极限在以下数值时达到：57±10.6瓦，心率125±11.8次/分钟，净心率27.4±3.6次/分钟，摄氧量1210±130毫升/分钟，耳道温度37.2±0.3摄氏度，出汗率577±96克。
