Physiological Reaction of the Body of Students to Regular Physical Activity

Systematic handball training stimulates the entire body and especially the heart. To improve the methods of practicing handball, it is necessary to further study the aspects of adapting the heart of young handball players to regular training. The study aims to find out the dynamics of the functional capabilities of the heart in youth handball players. The observation was carried out on 25 completely healthy youth handball players with at least 2 years of sports training experience. The control group included 24 healthy young men who did not go in for sports during their life. In all cases, the study was carried out on an SSD-80 "Aloka" ultrasound device (Japan), finding out several indicators of heart function. Statistical processing of all the results of the study was performed using the Student's t-test. The phenomena of mild hypertrophy of the wall of the left ventricle were revealed in young handball players. This was indicated by an increase in the thickness of the muscle of the posterior wall and an increase in the mass of the left ventricle of the heart myocardium. In all handball players, the volume of the left cardiac ventricle was optimal. They are also characterized by a high rate of diastole realization when compared with young men in the control group. Systematic handball exercises strengthen the entire body. Handball promotes the growth of muscle mass in the wall of the left ventricle, which significantly increases its ability to work and stimulates blood supply to the whole body.

“…In addition, chess is very important for optimizing leisure time, meeting communication needs, diversifying personality development, and expanding its communicative capabilities. The content of this adaptive sport is, first of all, in the formation of sportsmanship among disabled people and their achievement of good results among people with comparable health problems (Zavalishina et al, 2021b). In addition, with the help of adaptive sports, it is possible to maximize the development of a sick person's viability, preserve his/her psychophysical state at a sufficient level, giving each person the opportunity to realize his/her reserves (Zavalishina, 2018;Karpov et al, 2021b).…”

Adaptive chess sport can strongly stimulate the vitality of the patients and preserve their existing psychophysical potential through the exercise of creative and mental abilities. The effect of adaptive chess is based on the satisfaction of the psychophysical needs of those with weakened health, but preserved cognitive capabilities of the brain. Comparing the results of a questionnaire among middle-aged and elderly chess players with musculoskeletal problems in Moscow revealed a number of problems in the organization of adaptive chess sports. The most important problems were a reduction in the number of sports institutions of additional education and difficulties with the formation of the coaching staff in adaptive chess. The conducted research showed the high efficiency of regular chess trainings in terms of stimulating the chess player's body. Even subjects in the control group showed an increase in the effectiveness of playing chess by 43% in the first group and 93.5% in the second group compared to the preliminary stage of the study.

“…It is believed that swimming is a versatile and highly physiological type of muscle activity (Chistyakova, 2014;Moubarez et al, 2019;Hanawi et al, 2020;Zavalishina et al, 2021a). As a result of swimming, life processes in all organs are normalized .…”

Regular execution of movements while in the aquatic environment, ensuring the swimming process, heals the entire body. As a result of regular swimming, many positive changes occur in human tissues. As a result of systematic swimming training, a functional improvement of all human internal organs occurs. Frequent swimming training improves health and enhances the severity of physical and mental performance. Swimming strengthens the heart, improves vascular function, trains skeletal muscles, activates immunity, stimulates the breathing process, neutralizes most of the effects of stress, and tones all body tissues. Swimming is considered as a dosed physical activity that forms a stable positive emotional background and leads to the recovery of the whole organism. In the central nervous system, during the performance of motor actions in the aquatic environment, a more pronounced intensification of life processes occurs than during the performance of physical exercises on land. This effect is possible due to the stimulation of skin receptors with water. Private swimming training stimulates the autonomic nervous system. Swimming weakens the activity of its sympathetic part and increases the biological capabilities of its parasympathetic component. This contributes to the normalization of peripheral vascular tone, optimizes heart rate, lowers blood pressure, stimulates gas exchange processes, contributing to an increase in oxygen content in the blood, and intensifies metabolism in all cells.
