CORRECTION OF PHYSICAL FITNESS OF SENIOR SCHOOL STUDENTS LIVING IN RADIATION ENVIRONMENT

The deterioration of environmental living conditions has actualized the problem of preserving and strengthening the health of people. The research aims to study the adaptation capabilities of motor activity of senior school students living under conditions of radioecological factors' influence depending on the level of their physical activity; as well as to study possibilities of their correction by means of health improving physical education. According to the re-search results, it has been found that increased motor activity does not always have a positive impact of physical fitness. Not only low but also the increased physical activity is not adequate for a senior school student's body. It promotes stress adaptation mechanisms and functional capabilities reduction. The carried out monitoring detected that only senior school students having average and above average levels of motor activity have got satisfactory de-gree of adaptation. When planning and arranging physical education lessons at school, one should take into account the current status of students and individual adaptation characteristics to physical exercises. It allows implementing health improving effect of the lessons as efficiently as possible. The use of health improving physical education means at the lessons of physical training for senior school students allowed forming a high level of adaptation capabilities and increasing non-specific body resistance. As a result, it helps to reduce the negative influence of adverse radiation ecological factors.
