Summary. In order to assess the relative contribution o f aerobic processes to running velocity (v), 27 male athletes were selected on the basis of their middle-distance performances over 800, 1500, 3000 or 5000 m, during the 1987 track season. To be selected for study, the average running velocity ( 0 corresponding to their performances had to be superior to 90% of the best French of the season. Maximum 02 consumption (17o. . . . ) and energy cost of running (C) had been measured within the 2 months preceding the track season, which, together with oxygen consumption at rest (Vo ..... ) allowed us to calculate the maximal v that could be sustained under aerobic conditions: /3. . . . = ( g O 2 m a x - - l?o2ro~t)x C -1. The treadmill running v corresponding to a blood lactate of 4 mmol. l - 1 (V~a4), was also calculated. In the whole group, C was significantly, related to height ( r = - 0 . 4 3 ; P
