Thirty-eight female subjects (M +/ SD = 33 +/- 3.0 years) had VO2max measured on the cycle ergometer (M +/- SD = 37.3 +/- 6.4 ml.kg-1.min-1) and on the treadmill (M +/- SD = 41.3 +/- 6.6 ml.kg-1.min-1). VO2max was estimated for each subject from heart rate (HR) at submaximal workloads on the cycle ergometer using the Astrand-Rhyming nomogram (A/R) and the extrapolation method (XTP). VO2max was also estimated from three field tests: 1.5-mile run (RUN) (independent variable [IV] = time), mile walk (WALK) (IV = time, age, HR, gender, body weight), and the Queens College Step Test (ST) (IV = HR during 5-20 s recovery). Repeated measure ANOVA revealed significant mean differences between the criterion cycle ergometer VO2max versus A/R and XTP (20 and 12% overestimation). The WALK, RUN, and ST VO2max values were not significantly different from the criterion treadmill VO2max. The correlation between criterion VO2max estimated from the WALK and RUN were r = .73 (SEE = 4.57 ml,kg-1.min-1) and r = .79 (SEE = 4.13 ml.kg-1.min-1), respectively. The ST, A/R, and XTP had higher SEEs (13-13.5% of the mean) and lower r s (r = .55 to r = .66). These results suggest both the WALK and RUN tests are satisfactory predictors of VO2max in 30 to 39-year-old females.
38名女性受试者（年龄均值±标准差为33±3.0岁）在自行车测力计上测得的最大摄氧量（均值±标准差为37.3±6.4毫升·千克⁻¹·分钟⁻¹），在跑步机上测得的最大摄氧量（均值±标准差为41.3±6.6毫升·千克⁻¹·分钟⁻¹）。使用阿斯特兰德-瑞明诺模图（A/R）和外推法（XTP），根据自行车测力计次最大负荷时的心率（HR）估算每名受试者的最大摄氧量。最大摄氧量也通过三项现场测试估算：1.5英里跑（RUN）（自变量[IV]=时间）、一英里步行（WALK）（IV=时间、年龄、HR、性别、体重）以及皇后学院台阶测试（ST）（IV=5-20秒恢复期间的HR）。重复测量方差分析显示，标准自行车测力计最大摄氧量与A/R和XTP之间存在显著的均值差异（高估20%和12%）。WALK、RUN和ST的最大摄氧量值与标准跑步机最大摄氧量无显著差异。根据WALK和RUN估算的标准最大摄氧量之间的相关性分别为r = 0.73（估计标准误=4.57毫升·千克⁻¹·分钟⁻¹）和r = 0.79（估计标准误=4.13毫升·千克⁻¹·分钟⁻¹）。ST、A/R和XTP的估计标准误较高（为均值的13%-13.5%），相关性较低（r = 0.55至r = 0.66）。这些结果表明，WALK和RUN测试都是30至39岁女性最大摄氧量的满意预测指标。
