“…It is known that the results of the orthostatic test are influenced by various factors: dehydration [9], periods of the training cycle [10], the level of training [11][12][13], the nature of the loads [14], bed rest [15]. The effect of orthostatic test on heart rate Health, sport, rehabilitation Здоров'я, спорт, реабілітація Здоровье, спорт, реабилитация 6(4) variability in young hockey players was also revealed [16]. In addition, various authors [17][18][19][20][21] have shown the effect on the orthostatic test of various functional states and diseases of the central nervous system.…”

“…The degree of reduction of venous return of blood to heart at change of position of a body to a greater extent depends on a tone of large veins. If it is reduced, the increase in venous return may be so significant that the transition to an upright position due to a sharp deterioration in the blood supply to the brain may develop unconsciousness [16][17][18]. Low venous tone can also cause unconsciousness during prolonged stay in an upright position -orthostatic collapse [19][20].…”

Aim: to identify the influence of body length on the indicators of vegetative-vascular regulation of student-athletes. Material and methods. The study involved 42 second-year students who play sports at the amateur level (qualification level - 2-3 sports degree). The following research methods were used in the work: method of analysis of literary sources; method of determining body length; orthostatic test method; method of determining stroke volume and minute blood volume. Results. It was found that the increase in systolic blood pressure during the transition from horizontal to vertical position in students whose body length is above 190, significantly higher than in students whose body length does not exceed 175 cm (p <0.01) diastolic blood pressure, then in students whose body length is above 190 cm, this figure is significantly higher (p <0.01) both horizontally and vertically. The stroke volume of tall (more than 190 cm body length) students in the standing position is significantly less than that of students with a body length of 150-175 cm. There is a significant effect of body length on systolic blood pressure in the standing position, diastolic blood pressure in the supine and standing positions, heart rate in the supine and standing positions, stroke volume in the standing position, minute blood volume in the supine position and standing (p <0,001). The effect of body length on the orthostatic test was also significant for the following data: systolic blood pressure in the vertical position, diastolic blood pressure in the vertical position; change in diastolic blood pressure when changing body position from horizontal to vertical; heart rate in vertical and horizontal positions; change in heart rate during the transition from horizontal to vertical position; stroke volume of blood in the vertical position; change in stroke volume of blood during the transition from horizontal to vertical position; all indicators of minute blood volume. Conclusions. The state of the cardiovascular system of student-athletes is characterized by high fitness. It was found that students with a body length of more than 190 cm have difficulty with vegetative-vascular regulation.

“…There are insignificant regional features in HRV parameters of elite hockey players from sport schools, which are probably related to competitiveness (sport selection). Hockey players of the Ural region do not differ in terms of the total power of heart rate regulation with respect to hockey players from elite ice hockey sport schools aged 11-12 (Lyutfullin, & Almetova, 2014, Reutskaya, Kuznetsova, & Antipova, 2014. However, hockey players from the Ural region demonstrate greater contribution of cerebral-ergotropic influence and smaller contribution of vagal influence to heart rate regulation, which result in the increase of the stress index (SI).…”

“…The parameter of the parasympathetic nervous system reactivity (30:15) during orthostasis does not depend on the type of activity. In non-athletic schoolchildren aged 11-12 (Lyutfullin, Almetova, 2014) it is 30:15, the same as in hockey players.…”

The aim of this article is to study the peculiarities of heart rate variability (HRV) in elite hockey players aged 11-13 in terms of efficient selection in youth ice hockey. The study involved 37 elite hockey players aged 11-12 (n=17) and 13 (n=20) years. The standard methods of HRV assessment were used (statistical methods and spectral component). In addition, the method of variation pulsometry and the reactivity index of the parasympathetic nervous system (30:15) were applied. Selection efficiency in youth ice hockey was estimated using the youth league ranking, which is comprised of players in the first year after sport schools (aged 17-18). In hockey players aged 11-12 there was no connection between the parameters of heart rate variability and the league rank, where young athletes played after sport schools. In 13-year hockey players there is a strong direct correlation between RMSSD (r=0.95), АМо% (-0.59) and vegetative rhythm index (VRI) (-0.64). Therefore, HRV regulation in hockey players aged 11-12 is characterized by the absence of stress because of the dominance of parasympathetic influence on sinus node, which corresponds to age-related changes. Heart rhythm regulation in 13-year hockey players is accompanied by stress as a result of the increased influence of central mechanisms regulation under specific physical loads. Such indicators as RMSSD, АМо%, and VRI are important at the beginning of adolescence (13 years) for the assessment of selection efficiency in 11-13-year hockey players.
