Oxygen consumption during free level walking was determined in 114 children and teenaged subjects between the ages of 6 and 19 years and compared with a group of 47 normal adults. Subjects were divided into two age groups: children (6-12 years) and adolescents (13-19 years). The mean rate of oxygen uptake for children was significantly greater, 15.3 ml/kg/min, than the value for teenaged subjects, 12.9 ml/kg/min. The oxygen cost to walk a unit distance (meter) was higher in children than adolescent subjects. The mean values averaged .22 ml/kg/min and .18 ml/kg/min respectively. The data on heart rate paralleled the findings on oxygen consumption. The mean heart rate for children, 114 beats per minute (bpm), was significantly higher than the mean values for adolescent subjects, 97 bpm.
对114名6至19岁的儿童和青少年进行了自由水平行走时的耗氧量测定，并与47名正常成年人组成的一组进行比较。受试者分为两个年龄组：儿童（6至12岁）和青少年（13至19岁）。儿童的平均摄氧率显著更高，为15.3毫升/千克/分钟，高于青少年受试者的值12.9毫升/千克/分钟。儿童行走单位距离（米）的氧耗高于青少年受试者。平均值分别为0.22毫升/千克/分钟和0.18毫升/千克/分钟。心率数据与耗氧量的研究结果相似。儿童的平均心率为每分钟114次（bpm），显著高于青少年受试者的平均值97 bpm。
