The minimal velocity which elicits VO2max (vVO2max) is dependent on maximal aerobic power, running economy (RE) and neuromuscular factors. However, a direct comparison of the contribution of each parameter has not been studied yet. Thus, our main objective was to compare the magnitude of the influence of the VO2max, RE and maximal dynamic strength on the vVO2max. Nineteen recreational runners performed the following tests on three different days: 1) anthropometric measures and a maximal incremental running test; 2) two sub-maximal running tests to determine RE and; 3) a maximal dynamic strength test in the half-squat exercise (1RM). The RE was associated with 1RM relative to body weight at 12 km.h-1 (r=0.56; P<0.05). Moreover, a stepwise multiple regression model showed that the major influencing factors of the vVO2max were, hierarchically, VO2max, RE and 1RM. These data suggest that in recreational endurance runners, the maximal aerobic power is more important than RE or muscle strength to attain a higher vVO2max.
