The purpose of this study was to assess the relationship between VO2max and the aerobic demand of running (VO2submax) in elite distance runners. On at least one occasion, VO2max and VO2submax values were obtained on 22 male subjects (mean age = 27 +/- 2 yrs; mean height = 178.6 +/- 6.8 cm; mean body mass = 64.1 +/- 5.6 kg; mean 10 km run time = 28.89 +/- 1.05 min) training for the 1994 Olympic Trials. Subjects performed 6-min, submaximal level-grade treadmill runs at four speeds (ranging from 4.47 to 5.50 m.s-1) to determine VO2submax. VO2 during each run was calculated by analyzing a 2-min gas sample collected during the last 2 min of running. These values were expressed relative to distance traveled and averaged to derive an overall VO2submax value. Shortly following these submaximal runs, VO2max was measured. When more than one set of VO2submax and VO2max data were available for a particular subject, the average of all tests was used. Results indicated that mean VO2max and VO2submax values were 75.8 +/- 3.4 ml.kg-1.min-1 and 184.6 +/- 8.6 ml.kg-1.km-1, respectively. Correlational analyses also revealed a significant relationship (r = 0.59; p < 0.01) between VO2max and VO2submax. These data suggest that among similarly-performing elite distance runners, a positive relationship exists between VO2max and the aerobic demand of running.
本研究的目的是评估优秀长跑运动员的最大摄氧量（VO2max）与跑步有氧需求（VO2submax）之间的关系。在至少一次测试中，获取了22名男性受试者（平均年龄 = 27 ± 2岁；平均身高 = 178.6 ± 6.8厘米；平均体重 = 64.1 ± 5.6千克；10公里跑平均用时 = 28.89 ± 1.05分钟）的VO2max和VO2submax值，这些受试者正在为1994年奥运会选拔赛进行训练。受试者在水平坡度的跑步机上以四种速度（4.47至5.50米·秒-1）进行6分钟的次最大强度跑步，以确定VO2submax。每次跑步期间的VO2通过分析跑步最后2分钟收集的2分钟气体样本进行计算。这些值相对于行进距离表示，并进行平均以得出总体VO2submax值。在这些次最大强度跑步后不久，测量VO2max。当某个特定受试者有不止一组VO2submax和VO2max数据时，使用所有测试的平均值。结果表明，VO2max和VO2submax的平均值分别为75.8 ± 3.4毫升·千克-1·分钟-1和184.6 ± 8.6毫升·千克-1·公里-1。相关分析还揭示了VO2max与VO2submax之间存在显著关系（r = 0.59；p < 0.01）。这些数据表明，在表现相似的优秀长跑运动员中，VO2max与跑步的有氧需求之间存在正相关关系。
