Rectal and skin temperature and sweat rate were measured in eight 11-year-old boys exercising one hour on a bicycle ergometer at each of three different work loads. Rectal temperature rose according to the relative work load and reached a steady state level after a shorter time than had been previously observed in adult subjects. A good relationship was observed between the levelling off value of rectal temperature during work and the relative work load, but the value of rectal temperature at rest just before the start of work affects this steady state value. The average skin temperature was kept fairly constant during exercise except on the heaviest work load (70%), during which it rose about 1 degree C mainly as a result of the rise in skin temperature on the arm, hand and thigh. Temperature increases on skin locations in general were minimal except on the back where the temperature decreased slightly. Sweat rate showed a close relationship to the absolute work load, and in this report the conclusion is supported that the 11-year-old boys regulate their body temperature during exercise at constant work load in the same way as do adult subjects.
对八名11岁男孩进行了测试，他们在自行车测力计上以三种不同的工作负荷分别锻炼一小时，期间测量了直肠温度、皮肤温度和出汗率。直肠温度随着相对工作负荷的增加而升高，并且比之前在成年受试者中观察到的时间更短就达到了稳定状态水平。工作期间直肠温度的稳定值与相对工作负荷之间存在良好的关系，但工作开始前的静息直肠温度值会影响这个稳定状态值。运动过程中，除了在最重的工作负荷（70%）时，平均皮肤温度保持相当恒定，在最重负荷时皮肤温度上升约1摄氏度，主要是由于手臂、手部和大腿皮肤温度的升高。一般来说，除了背部温度略有下降外，身体其他部位的皮肤温度升高幅度很小。出汗率与绝对工作负荷密切相关，在本报告中支持这样的结论：11岁男孩在恒定工作负荷的运动过程中调节体温的方式与成年受试者相同。
