THE INFLUENCE OF ONLINE FITNESS TRAINING ON THE FUNCTIONAL STATE OF THE CARDIOVASCULAR SYSTEM IN SENIOR SCHOOLCHILDREN WITH EXCESSIVE BODY WEIGHT UNDER DISTANCE LEARNING

High school students, in connection with the preparation for entering universities, are overloaded not only with the school curriculum, but also have to study additionally. In such children, motor activity is significantly reduced, which leads to a weakening of adaptive capabilities of the leading systems of the body. The purpose of the study is to assess the impact of online fitness training on the development of the adaptive capabilities of the cardiovascular system in overweight high school students. The research was carried out on the basis of the Center for Design Creativity “StartPRO” in Moscow. Two groups were formed: a control group and an experimental one of 21 people each (girls), whose average age was 15.56 ± 1.14 years. Exercise adaptation was assessed by heart rate variability using the KARDi 2 electrocardiographic system. The survey was conducted twice, at the beginning and at the end of the study. The experiment lasted three months. The girls of the control group studied according to the standard school curriculum (Lyakh, Zdanevich) in a distance format. Recreational-training online aerobic classes were conducted 3 times a week for 3 months with the participants of the experimental group. According to the results of the ascertaining study of heart rate variability, 67 % of girls in both groups were in the zone of functional tension of the cardiovascular system and 33 % in the zone of normalcy. The inclusion of online health-improving training into the curriculum turned out to be effective and positively influenced the development of the adaptive capabilities of the cardiovascular system and body weight in the girls of the experimental group. Thus, the number of participants in the control group who passed into the normal functional state zone was 38 %, and in the experimental group — 57%. 70 % of the girls of the experimental group and 10 % of the control group showed a decrease in body weight to normal.
