Introduction. The number of people with vegetative-vascular dystonia has increased among students studying in a special medical department. According to researchers, physical exercises have a positive effect on the leading adaptive systems of the body, one of which is the cardiovascular system [2, 3]. A complex indicator of the functioning of the cardiovascular system - the adaptive potential of the circulatory system (AP) - can be a marker of the effectiveness of applied sports and wellness technologies [1, 3].
The aim of the study was to determine the effect of recreational gymnastics on the functional reserves of the circulatory system of female students with vegetative–vascular dystonia.
Methodology and organization of the study. The scientific work was carried out at the North Caucasus University in the classes of health culture in the system of additional education, it was attended by students of the special medical department with vegetative vascular dystonia (n=63). The experimental group consisted of female students engaged in additional recreational gymnastics (n=23), the control group consisted of female students engaged in a standard program (n=40). Fitball gymnastics was chosen as a health-improving technique.
The results of the study and their discussion. At the end of the year in the experimental group, the average values were 2.11±0.05 units, which corresponds to the exponent of the tension of the adaptation mechanisms. In female students engaged in additional health-improving exercises, 1,795 ± 0.06 units and corresponds to the indicator of incomplete or partial adaptation. When considering the gradients of the distribution of indicators of the level of functional reserves according to AP, after a course of fitball gymnastics exercises in female students with vegetative-vascular dystonia, 18.9% of female students had an optimal level of functional reserves of the circulatory system and 61.8 – sufficient, 19.3% still had a level of tension of adaptation mechanisms. In the control group of female students, 14.7% of female students and 53.3% of female students had a sufficient level of adaptive capabilities within the boundaries of the optimal level of adaptive capabilities of the circulatory system. Nevertheless, 28.2% of female students were in a state of tension of adaptation mechanisms and 3.8% were in a state of unsatisfactory values of adaptation processes of the circulatory system. At the same time, no such students were identified in the experimental group.
Conclusion. Health fitball gymnastics classes in the system of additional education have a positive effect on the functional reserves of the circulatory system of female students with vegetative-vascular dystonia. In our opinion, it is necessary not only to diagnose changes in the state of the leading adaptive systems of the body in time, but also to introduce sports and wellness correction methods in order to prevent and prevent further development of the disease.
