Scientific justification for the use of Nordic walking when modernizing the content of «Elective courses in physical culture and sports» among students of medical universities, undergoing COVID-19

Relevance. In the curricula of medical universities there is a discipline «Elective courses in physical culture and sports». Within its framework, organized classes are held with students from 1 to 5 courses of all faculties during the academic year for 2 hours a week using traditional means and methods. At the same time, a new type of physical activity is becoming more and more popular - Nordic walking, which is used in the physical rehabilitation of patients with diseases of the cardiovascular, respiratory, nervous systems. Therefore, the study aimed at modernizing the content of the «Elective Courses in Physical Culture and Sports» among students who have recovered from COVID-19 is relevant and timely. The purpose of the study is to scientifically substantiate the feasibility of modernizing the content of the work program of the «Elective Courses in Physical Culture and Sports» through the introduction of Nordic walking among students who have undergone COVID-19. Methods. At the beginning and at the end of the school year, the IPC and a set of standard indicators of external respiration were recorded. Methods of mathematical statistics (Statistica 10) were used. Outcomes. Analysis of the data at the beginning of the study showed that even after a mild form of COVID-19 disease, the functional reserves of the cardiorespiratory system decrease. Adequate physical activity within the framework of organized classes at the university contributes to the restoration of functions. The maximum increase in aerobic performance and functional reserves of respiration is observed in the group of female students engaged in Nordic walking. Conclusion. The expediency of modernizing the content of the work program of «Elective courses in physical culture and sports» at the university through the introduction of Nordic walking is scientifically substantiated. It could be recommended as an additional means of physical rehabilitation not only after covid, but also in the spread of other acute respiratory infections, not only for the purpose ofrehabilitation, but also for prevention related to the professional activities of students in medical organizations.
