Aerobic physical fitness, as determined by the body's maximal capacity to utilize oxygen (VO2max) during demanding work, is an important determinant of a person's ability to perform many military tasks. The present 2.4 km (1.5 mi) run has not proven itself capable of accurately estimating this important factor on a periodic basis. This paper reviews prior studies of heart rate response to known workloads on a cycle ergometer to estimate VO2max. This submaximal test, as revised by scientists at the USAF Armstrong Laboratory at Brooks AFB, TX, was validated on 22 male subjects by comparing the test results with laboratory measurements of VO2max obtained by analysis of expired air during maximal treadmill exercise. Two groups of subjects were selected; one consisting of highly trained runners and the other of inactive subjects who did not perform regular aerobic exercise. The cycle ergometry prediction underestimated measured VO2max by 8.1 ml.kg-1 x min-1 (SEE = 4.25) in all subjects, but there was a correlation of 0.95 between the estimated and measured values. Both estimated and measured VO2max were significantly higher in the group of trained runners than in the inactive subjects.
有氧体能，由身体在高强度工作期间利用氧气的最大能力（最大摄氧量）所决定，是一个人执行许多军事任务能力的重要决定因素。目前的2.4公里（1.5英里）跑并未证明自己能够定期准确地估计这一重要因素。本文回顾了先前关于在自行车测力计上对已知工作量的心率反应以估计最大摄氧量的研究。由德克萨斯州布鲁克斯空军基地美国空军阿姆斯特朗实验室的科学家修订的这种次最大测试，通过将测试结果与在最大跑步机运动期间通过分析呼出气体获得的最大摄氧量的实验室测量值进行比较，在22名男性受试者身上得到了验证。选择了两组受试者；一组由训练有素的跑步者组成，另一组由不进行定期有氧运动的不活动受试者组成。在所有受试者中，自行车测力计预测值比测量的最大摄氧量低8.1毫升·千克⁻¹·分钟⁻¹（估计标准误差=4.25），但估计值与测量值之间的相关性为0.95。训练有素的跑步者组的估计和测量的最大摄氧量均显著高于不活动受试者组。
