Purpose: The aim of this work to determine the influence of a program containing exercises in a closed kinematic chain, eccentric and strength exercises on injuries of students – rock climbers. Methods: Participants in this study were 84 male amateur climbing students, aged 18–19, 40 athletes were in the intervention group and 44 in the control group. In the intervention group, the program for the injuries prevention has been stalled. The program included exercises that are performed in a closed kinematic chain in combination with exercises that are performed in eccentric mode and strength exercises. We determined the Incidence rate ratio and confidence intervals. The Incidence rate ratio was determined by the by Fisher exact test. Results: The significant influence of the developed program on the reduction of injuries among the athletes of the intervention group was revealed. Injury rate per 1000 AEs recorded of all shoulder injuries in the control group was 3.182, in the intervention group was 0.5, P < 0.001. The incidence rate ratio for mild shoulder injuries was 0.861 (0.737; 1.007). The incidence rate ratio for moderate shoulder injuries was 0.862 (0.751; 0.990; P = 0.039). The incidence rate ratio for severe shoulder injuries was 0.864 (0.768; 0.971; P = 0.017). Conclusions: The use of exercises in a closed kinematic chain and exercises in an eccentric mode reduces the Incidence rate ratio of shoulders among students – amateur climbers. The incidence rate ratio decreases in the intervention group for mild, moderate, and severe shoulder injuries.

Purpose:to find the place of physical exercises' mastering level in structure of 11-13 yrs age boys' motor fitness. Material:in the research 11 yrs age boys (n=58), 12 (n=76) and 13 years age (n=93) participated. Testing program included well-known tests: "Forward roll", "Backward roll", "Vault", "Climbing rope (three attempts)", "Bridge", "Stance on shoulder blades". Results:By indicators of physical condition 11-13 yrs age boys statistically confidently differ one from another (р<0,001). Level of mastering of gymnastic exercises "Backward roll", "Vault", "Climbing rope (three attempts)", "Bridge", "Stance on shoulder blades" with age statistically confidently increases (р<0,001). Conclusions:In factorial structure of motor fitness, level of physical exercises' mastering has weight 17,5% (11 yrs age), 36,6% (12 years), 28,5% (13 years). Analysis of communities showed that in 11-13 yrs age boys training of motor abilities is effective (if they become a component of mastered motor skills).

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.

Purpose:the systematization of modern strategies for regulating the motor activity of preschool and school-age children. The criteria for assessing motor activity taking into account the individual characteristics of children and sociocultural conditions are considered. The adaptive strategy of regulation of the motor activity of a growing person in modern educational space is substantiated. Material:10 theses and more than 80 papers published in specialized journals of Russia, Ukraine, Kazakhstan, Belarus were analyzed. In the article is used quantitative approach, which has research and descriptive character. This approach includes methods for examining documents. The identification of studies over the past 50 years has been carried out. The analysis of normative program-methodological materials, educational standards, exemplary educational programs and the results of their own research was carried out. These studies substantiated various approaches to regulating and forming positive dynamics of motor activity in preschool and school-age children. Results:Three strategies for regulating motor activity were identified: biological, value-social and biosocial (adaptive). Their compliance with the level of scientific and methodological knowledge and domestic experience is established. The limiting factors have been established and ways of transforming the system of physical education at different levels of education have been concretized. The modern adaptive strategy of regulation of the motor activity of preschool children and younger schoolchildren is substantiated. The expediency of its introduction into the educational process is shown. This creates a favorable environment for the physical development of children. Conclusions:The adaptive system for regulating motor activity should take into account: the interests and opportunities of children at all levels of the educational system; regional sports traditions; sociocultural and climatic conditions. It is extremely important to recreate the playing space of childhood. This contributes to the formation of an active position in relation to the physical culture of the individual.

The purpose of the study is to determine the correlation of psycho-physiological functions with indicators of physical and technical readiness of young footballers of 12-13 and 15-16 years in the preparatory and competitive periods of the annual cycle of the training process. Methods. 24 football players participated in the study, 12 of them 12-13 players; 12 football players 15-16 years old. Parameters characteristic for determining the psychophysiological state, indicators of the nervous system's work capacity, and attention indicators were analyzed with the help of computer programs for psychophysiological testing. Also, determination of the level of physical preparedness (running on 60 m, running on 1000 m, shuttle running, pulling on the crossbar, jumping from place), determination of the level of technical preparedness (juggling, impact on range). Testing was carried out at the beginning of the preparatory period and at the beginning of the competition period of the annual cycle of the training process. The gap between the two tests was 3 months. Results. In the preparatory period of young footballers 15-16 years, the total number of reliable relationships between psychophysiological indicators and indicators of physical and technical preparedness is lower than that of young footballers 12-13 years in the preparatory and competitive periods. In the competitive period of 15-16 year old football players there is an increase in the number of interconnections between psychophysiological indicators and indicators of physical and technical preparedness compared with the preparatory period. In footballers aged 15-16 in the competitive period, there is an increase in the number of relationships that reflect rapid physical qualities and mobility of the nervous system, the ability to switch attention, the speed of a simple and complex reaction in comparison with the preparatory period and the results of testing the players 12-13 years. Conclusions. The obtained data is a reflection of the process of formation of a specific type of football player, when the speed of neurodynamic processes is associated with high-speed and speedstrength physical qualities.
