Oxygen uptake during treadmill running was measured at submaximal and maximal intensities in six different groups of endurance athletes (N = 134) and in seven endurance-trained men. The relationship between body mass (M) and oxygen uptake (VO2) was evaluated by deriving the exponent b in the equation VO2 = a.Mb. Thus, if b = 1, the oxygen uptake increases in proportion to body mass and oxygen uptake per kg is independent of body mass; if b less than 1, than the oxygen uptake per kg is inversely related to body mass. The exponent b was found to be less than unity for all groups for both submaximal (b = 0.76, s = 0.06) and maximal oxygen uptake (b = 0.71, s = 0.05). These results indicate that neither submaximal nor maximal oxygen uptake increases in proportion to body mass during running. The relationship between submaximal oxygen uptake and body mass observed in this study may explain why the oxygen uptake per kg of body mass has been found to be higher for children than for adults.
在六种不同组别的耐力运动员（N = 134）以及七名经过耐力训练的男性中，测量了他们在次最大强度和最大强度跑步机跑步时的摄氧量。通过推导方程VO2 = a.Mb中的指数b，评估了体重（M）与摄氧量（VO2）之间的关系。因此，如果b = 1，摄氧量与体重成比例增加，每千克体重的摄氧量与体重无关；如果b小于1，那么每千克体重的摄氧量与体重呈负相关。对于所有组，在次最大摄氧量（b = 0.76，s = 0.06）和最大摄氧量（b = 0.71，s = 0.05）时，指数b均小于1。这些结果表明，在跑步过程中，次最大摄氧量和最大摄氧量均不会与体重成比例增加。本研究中观察到的次最大摄氧量与体重之间的关系，可能解释了为什么已发现儿童每千克体重的摄氧量高于成人。
