Eight boys aged 10-12 years performed three tests on each of three treadmill protocols. Each test was a continuous, progressively graded performance to exhaustion, but protocols differed in speed--(walk: 90 m . min-1, jog: 110 m . min-1, run: 130 m . min-1). The walk protocol was found inappropriate for VO2 max determination in children. Compared to the faster speeds, the walk test elicited a lower VO2 at exhaustion, and had lower reliability (0.56) and a high coefficient of variation (8%). For the Vo2 at exhaustion on the jog and run protocols the coefficient of variation was 3-5% and the reliability coefficient averaged 0.90, comparable to values seen for repeated trials in adults. The usually accepted VO2 max criterion of a plateau of VO2 with increasing work levels was inappropriate for use with children. Attempts to derive plateau criteria suitable for use with children proved unsuccessful. Plateau criteria may be difficult to achieve with children in light of their apparently weaker glycolytic energy capacity. Nevertheless, the highest VO2 measured at jog or run speeds has a consistency similar to that found for Vo2 max measurement in adults.
八名年龄在10至12岁的男孩在三种跑步机运动方案下分别进行了三项测试。每项测试都是持续进行、逐渐递增强度直至力竭，但各方案的速度不同（步行：90米/分钟，慢跑：110米/分钟，跑步：130米/分钟）。研究发现步行方案不适用于测定儿童的最大摄氧量。与较快速度相比，步行测试在力竭时的摄氧量较低，可靠性也较低（0.56），变异系数较高（8%）。对于慢跑和跑步方案力竭时的最大摄氧量，变异系数为3%至5%，可靠性系数平均为0.90，与成年人重复试验的数值相当。通常所接受的随着工作强度增加最大摄氧量达到平稳状态的标准不适用于儿童。试图推导适用于儿童的平稳标准的尝试未获成功。鉴于儿童明显较弱的糖酵解能量能力，可能难以达到平稳标准。然而，在慢跑或跑步速度下测得的最高摄氧量具有与成年人最大摄氧量测量结果相似的一致性。
