Improvement of front crawl technique among swimmers-teenagers

Determination of appropriate stroke structure during its formation, making new adjustments in the swimming technique of puberty age boys to avoid the emergence of a stable dynamic stereotype cause the relevance of this study. The article highlights the issues of efficient swimming technique formation among 12-13 year-old boys taking into account the physiological mechanisms of the formation of motor skills. In the proposed methodology were used special exercises to correct basic errors, specific to this training phase. The training program included funds, directly affecting kinematic stroke structure. The study involved 23 young athletes from the junior swimming team of Krasnodar region. Research methods: every two months testing of swimmers' technical readiness using the method of computer video analysis of movements was conducted. Results: the indicator analysis of the length of the "step" and the tempo of the movement, as well as their optimum ratio at a competitive rate among all investigated swimmers of the experimental group showed the increase of the step length to 15,62%, wherein tempo reduction was only to 5,14%. In this way, at the training stage (stage of sport specialization), as well as the transition of athletes to the stage of the development of sport skills, it is recommended to plan their training taking into account the individual development of a teenager, his morphological features. Herewith the share of technical training is advisable to increase without load forcing, using a variety of technical means to improve the stroke structure.
