Assessment and effectiveness of the impact of health and rehabilitation measures on the adaptive reserves of the organism of adolescent schoolchildren

Abstract

Abstract. Adaptation to new socio-ecological conditions, the ever-increasing intensification of the educational process, and significant mental and emotional stress against the backdrop of limited physical activity cause tension in regulatory and compensatory mechanisms and require a new approach to the development of scientifically based health and rehabilitation measures. The purpose of the study is to assess the impact of health and rehabilitation measures on the adaptive abilities of adolescent students to the educational process and to verify their effectiveness. The article uses the following methods: theoretical; pedagogical observation; questioning; physiological and mathematical methods. The results of the study showed that the circulatory system, which is an indicator of the body's general adaptive reactions, plays a leading role in ensuring the body's adaptive reserves. It was found that the failure of adaptation in middle school students was 16.5%, which indicates a high probability of diseases occurring under conditions of excessive stress that do not correspond to the physiological capabilities of students of this age. A comparative analysis of the psychological state of students showed that the level of total deviation decreases during the school year, while the percentage of children with reduced and excessively high deviation indicators increases. Thus, the maximum level of anxiety contributes to a decrease in adaptive changes in the functional state of the cardiovascular system. The use of preventive and rehabilitation measures (optimization of the daily routine, adjustment of the school schedule, morning exercises, physical activity breaks, health and physical education relaxation classes) significantly improve the physiological and psychological adaptation of schoolchildren to the educational process. Conclusions. The results of the study confirm the feasibility of health and rehabilitation measures and require further research to improve the organizational forms of work in general secondary education institutions and the introduction of
