Introduction. As a result of the activation of muscular activity, it is often possible to achieve significant improvement of the body [2]. This is especially evident in adolescence, when it is possible to stimulate the processes of natural growth and development against the background of an existing defect in the body [1]. In this regard, it is important to continue studying the influence of adaptive sports on the adolescent body with pathology of the visual analyzer.
The purpose of the study is to evaluate the dynamics of physical abilities of visually impaired adolescents who started adaptive football classes.
Methodology and organization of the study. 22 visually impaired teenage boys aged 13-14 were observed. They formed two groups: a group of trainees (12 people), consisting of those who started practicing adaptive football, and a group of non-trainees (10 people) who regularly attended physical education classes at school. The work takes into account the results of medical examinations of the observed adolescents and the data of their functional testing for physical fitness. The results were processed by the Student's t-criterion.
The results of the study and conclusions. Before the start of the study, all adolescents had low physical abilities and did not differ between the groups. At the end of the observation, there were no changes in the considered indicators in the group of non-trainees. Against the background of regular adaptive football training, an increase in physical fitness indicators was noted in the group of trainees after 4 months. This was confirmed by an increase in their speed and strength abilities (running at 30 m accelerated by 22.1%, running at 60 m accelerated by 19.6%, the length of the jump from a place increased by 16.8%). At the same time, their strength endurance indicators increased (the number of pull-ups performed on the crossbar increased by 34.5%, there were 32.6% more trunk lifts from the prone position for one minute), coordination abilities improved (shuttle running time decreased by 17.2%, the number of rope jumps increased by 38.2% during 25 seconds), the indicators of overall endurance increased (the distance run in 6 minutes increased by 14.7%).
Conclusion. In the case of regular adaptive football training, visually impaired adolescents improve their coordination abilities, speed characteristics, strength increases and endurance increases. The physical activity of their peers only in physical education classes at school does not lead to significant changes in the parameters taken into account, leaving them low.
