“…Морфофункциональная перестройка отражается на параметрах физического развития юных хоккеистов [9], в спортивном отборе повышается значение морфологических [8,10], функциональных и других показателей [15]. Гиперфункция гипоталамических структур и гипофиза, увеличение продукции стрессгормонов и андрогенов [13] на фоне усиления секреторной активности щитовидной железы приводит к напряжению регуляции в функциональных системах организма [2]. Подготовка спортсмена часто проходит на фоне недостаточно полного восстановления организ-ма [4,12], что увеличивает психофизиологическую «цену» адаптации.…”

Aim. The article deals with studying the features of sensorimotor integration and movement coordination in elite hockey players aged 15–16. Materials and methods. A prospective longitudinal study was performed in the competitive phase of preparation. Hockey players aged 15–16 participated in the study (n = 36; attackers and defenders). The control group consisted of 16-year-old students from the college of physical education (n = 15). We performed an examination with the help of NS-PsychoTest software and hardware equipment (Russia, Neurosoft). We assessed the functional status of cortical centers of the nervous system, as well as the speed and accuracy of simple and complex eye-motor reactions. We determined the level of sensorimotor and voluntary movement coordination with the help of tremorometry. Results. Compared to peers, hockey players aged 15–16 possess a higher level of functional indicators under interference conditions (p < 0.05 in all cases) and a better indicator of the concentration of excitation (p < 0.001). Hockey players are characterized by a better speed and accuracy of reaction under interference conditions (p < 0.001 in all cases) and better reaction to a moving object (p < 0.05 in all cases). Compared to peers not-involved in sports, elite hockey players aged 15–16 are characterized by a higher level of voluntary movement coordination with a static form of muscle contraction (p < 0.01). Conclusion. The specific conditions of the competitive activity of hockey players aged 15–16 contribute to an increase in the efficiency of the central nervous system under interference conditions by improving the concentration of excitation. Sensorimotor integration of the players of this age is also distinguished by better predictive accuracy in reactions to a moving object. The parietal-premotor level of movement regulation in hockey players develops in accordance with age-related features, while specific physical loads influence the improvement of voluntary movement coordination with a static form of muscle contraction.

“…Morphofunctional changes are reflected in the physical development of young hockey players [8]; in sports selection, the importance of morphological [9; 10], functional and other indicators increases [11]. Hyperfunction of hypothalamic structures and the pituitary gland, an increase in stress hormones and androgens against the background of increased secretory activity of the thyroid gland leads to regulatory tension in the functional systems of the body [12].…”

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.

“…In sports selection, the importance of morphological [3; 4], functional and other indicators [5] increases. Hyperfunction of hypothalamic structures and the pituitary gland, an increase in stress hormones and androgens against the background of increased secretory activity of the thyroid gland lead to regulatory tension in the functional systems of the body [6]. Athlete training often takes place against the background of insufficient recovery of the body [7; 8], which increases the psychophysiological "price" of adaptation.…”

The purpose of the article is to study the dynamics of psychophysiological indicators of elite hockey players aged from 15 to 16 years in an annual training macrocycle. Materials and methods: during July, December and February, elite hockey players aged 15-16 were examined. We studied the speed and accuracy of hand-eye reactions, the level of sensorimotor and voluntary movement coordination, the functional status of the central nervous system (CNS). Mental state was determined by the Lusсher сщдщк test. The software and hardware complex NS-Psychotest (Russia) was used in the work. Results: by the end of the competitive period, the interference resistance of hockey players is increased by improving the concentration of excitation processes. Sensorimotor and voluntary coordination of movements changes only with the static form of muscle contractions. The mental status of hockey players 15-16 years old in the dynamics of the annual training macrocycle varies from the conditional norm to stress, which requires individual corrective measures
