Assessment of the effectiveness of a swimmer's undulatory exit after the start

The purpose of the study is to investigate the effectiveness of gliding during the underwater phase of the post‑start segment and to develop a methodology for assessing the effectiveness of a swimmer's undulatory exit after the start. Research methods: analysis and generalization of scientific literature data, pedagogical observations, pedagogical experiment, testing, and mathematical statistics methods were used. Research results and conclusions. An original methodology for assessing the effectiveness of a swimmer's undulatory exit after the start was developed. The methodology was tested in the training process of the swimming team of Peter the Great St. Petersburg Polytechnic University (SPbPU). The reliable implementation of the assessment of the effectiveness of the swimmer's undulatory exit after the start, revealed during the study, indicates the positive effect of the applied methodology. The obtained result allows the conclusion that it is advisable to include the proposed method in the set of training tasks.
