BACKGROUND: To determine the features of heart rate variability in hockey players aged from 13 to 16.
METHODS: A total of 97 hockey players aged 13 to 16 years who were studying at the specialized children’s and youth school of the Olympic reserve of the Ural region of Russia were examined. The ECG was recorded at rest and during an active orthostatic test. Standard methods of time analysis, frequency analysis of heart rate variability (HRV) and variational pulseometry were used in the work. The reactivity of the parasympathetic autonomic nervous system was determined by a factor of 30:15 in the transition period of the active orthostatic test.
RESULTS: The most significant changes in the parameters of HRV in hockey groups occur at 16 years: a lower CV value relative to hockey players of 14 years (P<0.001), a larger value of RMSSD relative to hockey players of 13 years (P<0.05) and a lower value of VLR relative to all younger age Groups of players (P<0.05, P<0.05 and P<0.01, respectively). The total power of regulation (TR) in all age groups of hockey players was the same. At 16 years, hockey players have more HF and HF%, while less VLF% relative to hockey players 13 years; Less VLF and VLF% relative to hockey players 14 years. The value of the coefficient of 30:15 hockey players is 14 years, 15 years and 16 years more relative to hockey players of 13 years (P<0.01, P<0.001 and P<0.001, respectively). The ratio of hockey players of 13-16 years with I, II, III and IV types of regulation differed depending on age. At 13 years the ratio was: 36%: 7%: 50%: 7%; In 14 years: 25%: 0%: 46%: 29%; In 15 years: 36%: 0%: 46%: 18%; In 16 years: 15%: 2%: 73%: 10%.
CONCLUSIONS: By the age of 16, hockey players have an increase in the overall effect of heart rate regulation by increasing the influence of the parasympathetic nervous system and reducing the effect of cerebral-ergotropic regulation mechanisms, which is accompanied by a decrease in the heart rate. By the age of 15, the reactivity of the parasympathetic nervous system of hockey players in an active orthostatic test increases. In groups of hockey players of adolescence, the distribution by type of regulation differs depending on age. The number of types with the predominance of autonomous regulatory mechanisms increases at the age periods from 13 to 14 years and from 15 to 16 years. The relative number of hockey players with the IV type of heart rate regulation decreases from 14 years to 16 years. The greatest tension in the mechanisms for the heart rate regulation of hockey players is observed in 13 years and 15 years.
