THE INFLUENCE OF THE PHYSICAL ACTIVITY OF A MODERN STUDENT ON THE CHARACTERISTICS OF THE CARDIOVASCULAR AND RESPIRATORY SYSTEMS AND THEIR RESISTANCE TO STRESS DURING EDUCATIONAL PROCESS

Many students in the educational process are subject to emotional, cognitive, motivational stress. A little physical activity allows them to get out of this state. One aspect of the research of adaptation of the students to the educational and physical loads is the investigation of their cardiovascular and respiratory systems state. There were investigated 100 students (educational directions: "Physical culture", "Music", "General Medicine") (age 19-24) from Kazakhstan, Russia, Turkey with different levels of physical activity in the process of their adaptation to educational process Anthropometric measurements were used to assess the parameters of physical development. The method of variational pulsometry by R.M. Baevskiy and spirometry were used to assess the functional state of the both systems. Stress resistance to learning and physical loads was determined due to assess the indices of general aerobic and speed-strength anaerobic endurance, survey among students. It was shown that students with a low level of physical activity are characterized by a pronounced predominance of the sympathoadrenal chain of heart rhythm regulation, which indicates a significant stress of adaptation mechanisms. The effectiveness of the regulation of heart rate in students of the educational direction "Physical Culture" is higher, which indirectly proves the positive impact of systematic physical activity on the functioning of the cardiovascular system and the body as a whole. It is advisable to solve the problem of the lack of physical activity of students by including various forms of physical education in their educational everyday activities that can be regulated daily by teachers. At the same time, the systemic nature of the physical impact on the student body is ensured by the interconnection of all forms of physical activity and types of motor activity, the content and direction of which is constantly updated considering the hierarchy of goals.
