The individual physical efficiency was ascertained according to a method developed by RUTENFRANZ, where the criterion was taken as being the particular performance which resulted in a pulse rate of 170 beats per minute. This was termed the p.w.c. 170 (physical working capacity), and was measured on a bicycle ergometer, with increasing loading of 1, 2, and 3 watt per kilogram of body weight. During this loading the E.C.G. was watched telemetrically on an oscilloscope, and recorded each minute. The p.w.c. 170 was ascertained both graphically and arithmetically from the respective pulse rate in the 6th minute of each load level. Initially, twenty healthy children were tested, so as to arrive at normal values. The average reading for these children was about 5% below the normal values given by RUTENFRANZ. Subsequently, fifty five obese children were examined, so as to clarify the question as to whether there was a linear correlation between overweight and physical efficiency. Indeed, it was possible to establish a regression equation according to which each 10% of overweight lead to a decrease of physical efficiency of 5.8%. The results of further examinations will be reported in the next paper.
个体身体效率是根据鲁滕弗兰兹开发的一种方法确定的，该方法将导致每分钟脉搏率为170次的特定表现作为标准。这被称为p.w.c. 170（身体工作能力），并在自行车测力计上进行测量，体重每千克的负荷以1、2和3瓦的幅度递增。在加载过程中，通过示波器遥测观察心电图，并每分钟记录一次。p.w.c. 170通过图形法和算术法从每个负荷水平第6分钟的相应脉搏率中确定。最初，对20名健康儿童进行了测试，以得出正常值。这些儿童的平均读数比鲁滕弗兰兹给出的正常值低约5%。随后，对55名肥胖儿童进行了检查，以澄清超重与身体效率之间是否存在线性相关性的问题。实际上，可以建立一个回归方程，根据该方程，每超重10%会导致身体效率下降5.8%。进一步检查的结果将在下一篇论文中报告。
