The article aims to identify the features of heart rate variability in elite hockey players aged 15-16 years(n = 36) in the annual training cycle. Heart rate variability was studied in the preparatory and competitive preparation periods (July-December-February). The comparison group consisted of students of a college of physical education of a similar age (examination time: February). In the work, standard methods for assessing HRV at rest (time domain and spectral analysis method) were used. The reactivity coefficient of the parasympathetic system (30: 15) in response to orthostasis was calculated. By the middle of the competitive period, VLF waves decrease; HF waves increase from 34% to 43% and there is a decrease in VLF waves. The ratio of the power of spectral waves changes from LF
