Maximal Time Spent at VO2max from Sprint to the Marathon

Abstract

Until recently, it was thought that maximal oxygen uptake (VO_2max) was elicited only in middle-distance events and not the sprint or marathon distances. We tested the hypothesis that VO_2max can be elicited in both the sprint and marathon distances and that the fraction of time spent at VO_2max is not significantly different between distances.

Methods: Seventy-eight well-trained males (mean [SD] age: 32 [13]; weight: 73 [9] kg; height: 1.80 [0.8] m) performed the University of Montreal Track Test using a portable respiratory gas sampling system to measure a baseline VO_2max. Each participant ran one or two different distances (100 m, 200 m, 800 m, 1500 m, 3000 m, 10 km or marathon) in which they are specialists.

Results: VO_2max was elicited and sustained in all distances tested. The time limit (Tlim) at VO_2max on a relative scale of the total time (Tlim at VO_2max%Ttot) during the sprint, middle-distance, and 1500 m was not significantly different (p > 0.05). The relevant time spent at VO_2max was only a factor for performance in the 3000 m group, where the Tlim at VO_2max%Ttot was the highest (51.4 [18.3], r = 0.86, p = 0.003).

Conclusions: By focusing on the solicitation of VO_2max, we demonstrated that the maintenance of VO_2max is possible in the sprint, middle, and marathon distances.
