Simple, valid, and reliable methods of estimating maximal oxygen uptake (VO2max) are needed for epidemiologic studies of physical activity, to evaluate fitness for job performance, and to assist in prescription of exercise. Such estimations in women have not received due research attention. Heart rate responses to submaximal cycle ergometry and VO2max during maximal treadmill and cycle ergometer testing were measured in 37 healthy women aged 19-47 yr (X = 31.7 +/- 7.9). The submaximal test was very reliable on retest (r = 0.92), but overestimated measured treadmill VO2max (X = 2.42 vs 2.23 l.min-1; r = 0.76, SEE = 0.229). The submaximal test also greatly overestimated maximal cycle ergometer VO2max (X = 2.42 vs 2.06 l.min-1; r = 0.70, SEE = 0.340). Similar 8.5% (treadmill) and 18.5% (cycle ergometer) overestimation by the submaximal test were found for VO2max relative to body weight. A simple submaximal exercise test is highly reliable as an estimate of VO2max when used for women. It also provides a reasonably good estimate of treadmill measured VO2max.
在体力活动的流行病学研究、评估工作表现的体能以及辅助运动处方时，需要简单、有效且可靠的方法来估计最大摄氧量（VO2max）。针对女性的此类估计尚未得到应有的研究关注。对37名年龄在19 - 47岁（X = 31.7 +/- 7.9）的健康女性，测量了次极量蹬车运动时的心率反应以及最大跑步机和蹬车运动测试期间的VO2max。次极量测试在复测时非常可靠（r = 0.92），但高估了测量的跑步机VO2max（X = 2.42对2.23 l.min-1；r = 0.76，SEE = 0.229）。次极量测试也极大地高估了最大蹬车运动VO2max（X = 2.42对2.06 l.min-1；r = 0.70，SEE = 0.340）。相对于体重，次极量测试对VO2max的高估在跑步机测试中为8.5%，在蹬车运动测试中为18.5%。当用于女性时，一个简单的次极量运动测试作为VO2max的估计是高度可靠的。它对跑步机测量的VO2max也能提供相当不错的估计。
