Search for indicators that determine the effectiveness of overcoming acyclic sections at 50, 100 and 200 meters in freestyle swimming

Purpose: to establish the most significant indicators affecting the athletic performance of highly skilled swimmers during the overcoming of acyclic sections at 50, 100 and 200 meters in freestyle swimming. Material & Methods: theoretical analysis and synthesis of scientific and methodical literature, pedagogical observation, video filming, timekeeping, methods of mathematical statistics. The surveyed group (n=24) consisted of highly qualified swimmers (MS, MSIG, HMS), take on at a distance of 50, 100 and 200 meters freestyle. Results: the peculiarities of overcoming starting and turning sections at distances of 50, 100 and 200 meters of freestyle were studied. The level of significance of the underwater phase after performing starts and turns relative to the 15 m mark is established. The degree of correlation relationship between time, speed and distance for the underwater phase for the speed of passage of various segments of distance is revealed. Conclusion: improvement of starting and turning techniques, due to the increase in speed and distance of the underwater phase, is one of the reserves for the further growth of the skill of swimmers who specialize in freestyle.
