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.
