The purpose of the study is to identify typological features of the dynamics of heart rate variability in elite hockey players in the annual training macrocycle. Materials and methods: during July, December and February, 15-16-year-old elite hockey players were examined. Heart rate variability was evaluated by standard methods. The reactivity coefficient of the parasympathetic nervous system in the transition period of the orthostatic test was calculated, as well as the type of heart rate regulation was determined. Results: typological features of heart rate regulation in elite hockey players aged 15-16 years are revealed. In the competitive period, there is an increase in the autonomy of regulatory processes due to the strengthening of the role of the bulbar center of cardiovascular activity, which begins earlier in hockey players with types III and IV. Restructuring of heart rate regulation in hockey players with types I and II is carried out for longer periods, in the middle of the competitive period it is reflected in the reactivity of the parasympathetic system in response to orthostasis.
