young swimmers with fins.
Materials and methods: 30 swimmers 9-11 years old, swimming with fins, took part in the study. The study was conducted during a two-year macrocycle of the training process. Anthropometry was used to assess physical development. The evaluation of physical development was carried out by the index method. The status of the functional reserves was investigated using the following tests: standard test with breath-holding, Rouffier's test, determination of the total and individual working capacity. The development of physical abilities was determined by swimming the distance of 50 m, 400 m, long diving.
Results: during the two-year regular training of young swimmers, a significant increase in the indices of physical development, functional reserves of cardiovascular and respiratory systems and indicators of physical abilities was recorded.
Conclusions: study showed a significant increase in the indicators of physical development, functional reserves and physical qualities.
Keywords:
