Integrated development of aerobic power and tactical variability as a foundation for training finswimmers for long‑distance open‑water competitions

The article addresses the issues of training finswimmers for long-distance open water events, where the result depends not only on aerobic capacity but also on tactical and navigational stability. The purpose of the study is to evaluate the effectiveness of the method of combined development of aerobic power and tactical variability. Research methods: analysis of scientific and methodological literature, pedagogical experiment, mathematical and statistical analysis. Research results and conclusions. The method of combined development of aerobic power and tactical variability has proven effective in preparing finswimmers aged 14–16 (1st category, Candidate for Master of Sports) for long-distance open water competitions. The practical value of this method lies in the fact that the coach receives a tool that allows the development of aerobic power in finswimmers not in isolation from competitive reality, but under conditions closely resembling the dynamics typical of open water. The method enhances the coach's control over training and ensures the transfer of competitive scenarios into safe training conditions for adolescent finswimmers.
