Optimizing the functional state of the cardiorespiratory system of female students aged 17-19 with the help of a modified program of distance classes in physical education

The article deals with the peculiarities of the impact of a modified program of distance training on physical education on the functional state of circulatory systems and external breathing of students of 17-19 years of higher education. The relevance and practical importance of this study is due to the complex modern conditions of life of our country, the inability to conduct full -fledged classes among student youth and the need to maintain the optimal level of physical and functional state of student youth. The use among female students of the experimental group of the program of remote classes proposed by us contributed to significantly higher rates of improvement in heart rate, all types of blood pressure, Robinson's index, total peripheral resistance of blood vessels, coefficient of efficiency of blood circulation, vital capacity of the lungs (in 2-3 times), breath retention time on inhalation and exhalation (3 and 5 times, respectively), Skibinsky index 5 times, hypoxia index (20 times) and almost 5 times the levels of the functional state of the cardiovascular system and the external system breath. The results of changes in their intragroup distribution by the levels of levels of functional state of circulatory and external respiration, which were reflected in the increase of their representation in functional classes high and above average, were significantly more optimal in the experimental group. Similar changes in the girls of the control group were insignificant. The results testified to the high efficiency of the proposed program of distance classes with the use of fitness and the possibility of its practical use among students of higher education.
