The correction of swimming techniques by way crawl on a breast at swimmers of high qualification, using the method of video is examined. The method of measurement of the kinematic structure of movements of the swimmer with subsequent processing and analysis of the received information was suggested. Assessment criterion of swimming techniques became the model-the reference swimming technique by way crawl on a breast, which deals with the underwater part of the stroke: the capture phase of the brush at the beginning and hand placement at the end of the tightening; the links of hands at the beginning and at the end of phase tightening; phase repulsion. For correction technique of swimming crawl on a breast developed and introduced into the training process experimentally grounded complex of exercises for groups of sports perfection, consisting of twenty exercises taking into account the mistakes made by examinees. The developed complex of exercises for correction swimming techniques can be used in the sports school and the sports school in groups of sports perfection. This technique does not require a high material and technical base and the process of operation is designed for basic knowledge of trainers.
