Abstract

Some studies were developed trying to determine: how body roll affects the pUlling path and the influence of breathing actions on stroke mechanics. The aim of this study was to determine the differences of arm movement kinematics in different breathing patterns and selected stroke drills in front crawl swimming. Whether breath-holding or breathing, swimmers do not change their amplitude of movement in the stroke depth, width and length. When the swimmer performs the stroke drill of one-arm front crawl with the resting arm extended in front, breathing on the moving side, the stroke depth is reduced due to the lack of body rotation. When a coach prescribes swimming drills he must consider their influence on body rotation and pUlling path. Both can be greatly modified by the no moving arm position and breathing co-ordination.
