The physiological performance of a group of boys and girls aged eleven to twelve years was examined and nineteen of these children were retested again at aged sixteen years. The findings of this investigation support the findings of other similar studies that, when VO2 max is used as a determinant of cardiovascular performance, the performance of children increases with age, and in boys particularly, this increase in associated with an increase in body weight. After puberty boys have a greater oxygen consumption and thus a greater physiological performance than girls, mainly as a result of an improved cardiorespiratory efficiency and a greater muscle to weight ratio. The improvement in their physiological performance by those girls particularly interested in sport, however, also suggests that this factor is most influential to performance during growth at adolescence.
对一组11至12岁的男孩和女孩的生理机能进行了检测，其中19名儿童在16岁时再次接受了测试。这项调查的结果支持了其他类似研究的结果，即当最大摄氧量被用作心血管机能的决定因素时，儿童的机能随年龄增长而提高，尤其是男孩，这种提高与体重增加有关。青春期后，男孩的耗氧量更大，因此生理机能比女孩更强，这主要是由于心肺效率提高和肌肉与体重比更高。然而，那些对运动特别感兴趣的女孩生理机能的提高也表明，这个因素在青春期生长过程中对机能影响最大。
