Times to exhaustion at 100% of velocity at VO2max and modelling of the time-limit/velocity relationship in elite long-distance runners.
The aim of this study was to measure running times to exhaustion (Tlim) on a treadmill at 100% of the minimum velocity which elicits VO2max (vVO2max in 38 elite male long-distance runners (VO2max = 71.4 +/- 5.5 ml.kg-1.min-1 and vVO2max = 21.8 +/- 1.2 km.h-1). The lactate threshold (LT) was defined as a starting point of accelerated lactate accumulation around 4 mM and was expressed in %VO2max. Tlim value was negatively correlated with vVO2max (r = -0.362, p < 0.05) and VO2max (r = -0.347, p < 0.05) but positively with LT (% vVO2max) (r = 0.378, p < 0.05). These data demonstrate that running time to exhaustion at vVO2max in a homogeneous group of elite male long-distance runners was inversely related to vVO2max and experimentally illustrates the model of Monod and Scherrer regarding the time limit-velocity relationship adapted from local exercise for running by Hughson et al. (1984).
