Abstract

The so-called velocity associated with O2max, defined as the minimal velocity which elicits O2max in an incremental exercise protocol (v O2max), is currently used for training to improve O2max. However, it is well known that it is not the sole velocity which elicits O2max and it is possible to achieve O2max at velocities lower and higher than v O2max. The goal of this study was to determine the velocity which allows exercise to be maintained the longest time at O2max. Using the relationship between time to exhaustion at O2max in the all-out runs at 90%, 100%, 120% and 140% of v O2max and distance run at O2max, the velocity which elicits the longest time to exhaustion at O2max (CV′) was determined. For the six subjects tested (physical education students), this velocity was not significantly different from v O2max (16.96 ± 0.92 km · h−1 vs 17.22 ± 1.12 km · h−1, P = 0.2 for CV′ and v O2max, respectively) and these two velocities were correlated (r = 0.88, P = 0.05).
