Effectiveness of a staged methodology for technical swimming training in qualified pentathletes based on biomechanical and pedagogical monitoring

The purpose of the study is to experimentally evaluate the effectiveness of the staged technical training methodology in swimming for qualified pentathletes within the structure of the annual training cycle. Research methods and organization. The study was conducted in the form of a pedagogical experiment involving 20 athletes aged 14–17 years (Category I – Candidate for Master of Sport). A phased methodology, based on the use of biomechanical analysis, video feedback tools, and pedagogical supervision, was implemented in the training process of the experimental group. The dynamics of technical and biomechanical indicators of swimming technique, as well as the performance of the swimming stage of the polyathlon, were evaluated. Research results and conclusions. In the experimental group, a statistically significant improvement was observed in stroke length, average swimming speed, and the dynamic efficiency index, accompanied by a simultaneous decrease in stroke frequency; in the control group, the changes were limited. Stable correlations between technique parameters and athletic performance were established. The data obtained confirm the effectiveness of the developed methodology and its practical significance for the training system of qualified pentathletes.
