The so-called velocity associated with VO2max, defined as the minimal velocity which elicits VO2max in an incremental exercise protocol (v(VO2max)), is currently used for training to improve VO2max. However, it is well known that it is not the sole velocity which elicits VO2max and it is possible to achieve VO2max at velocities lower and higher than v(VO2max). The goal of this study was to determine the velocity which allows exercise to be maintained the longest time at v(VO2max). Using the relationship between time to exhaustion at VO2max in the all-out runs at 90%, 100%, 120% and 140% of v(VO2max) and distance run at VO2max, the velocity which elicits the longest time to exhaustion at VO2max (CV') was determined. For the six subjects tested (physical education students), this velocity was not significantly different from v(VO2max) (16.96+/-0.92 km x h(-1) vs 17.22+/-1.12 km x h(-1), P = 0.2 for CV' and v(VO2max), respectively) and these two velocities were correlated (r = 0.88, P = 0.05).
所谓与最大摄氧量（VO2max）相关的速度，定义为在递增运动方案中引发最大摄氧量的最小速度（v(VO2max)），目前被用于训练以提高最大摄氧量。然而，众所周知，它并非引发最大摄氧量的唯一速度，在低于和高于v(VO2max)的速度下也有可能达到最大摄氧量。本研究的目的是确定能使运动在v(VO2max)下维持最长时间的速度。利用在v(VO2max)的90%、100%、120%和140%进行全力跑时达到最大摄氧量的疲劳时间与在最大摄氧量时跑的距离之间的关系，确定了在最大摄氧量时引发最长疲劳时间的速度（CV'）。对于测试的6名受试者（体育专业学生），该速度与v(VO2max)无显著差异（CV'和v(VO2max)分别为16.96±0.92 km·h⁻¹和17.22±1.12 km·h⁻¹，P = 0.2），且这两个速度具有相关性（r = 0.88，P = 0.05）。
