Four main characteristics were distinguished on the basis of an analysis of the velocity curve in sprint running which determine the special exercise capacities of a sprinter: a) the ability for rapid attainment of speed in start momentum; b) ability for attaining maximal strength; c) ability for maintaining maximal running speed; d) ability to resist fatigue in the final phase of running. These properties are relatively conditioned and effected, to different degrees, by training. Distinctions between qualified sprinters and beginners are observed in display of maximal running speed, but these distinctions are not observed in display of staring speed and in abilities to resist fatigue.
