摘要：The main aims of this study were i) to perform a kinematic characterization of sub and maximal swimming; ii) to investigate the associations between the kinematic profiles and the 200 m front crawl event. Nine national level male swimmers performed two tests: a submaximal discontinuous trial of progressive intensity, and a maximal one, simulating a 200 m front crawl event. The stroke general kinematic parameters, the phases duration of the stroke cycle, the velocity of the centre of mass and the intra cyclic variation of the horizontal velocity were studied. Significant kinematic differences in relation to stroke rate, horizontal velocity of the centre of mass, total cycle duration, absolute and relative duration of the propulsive sub aquatic action and the velocity of the centre of mass during the arms recovery were verified between the tests. Significant correlations between the performance in the maximal test and some kinematic variables were observed.
