The relevance of the work is associated with insufficient information on the impact of classes in the aquatic environment on the functional state of persons who have undergone coronavirus infection, the lack of formulated regimes of hydrorehabilitation measures for athletes with postcoid syndrome. The article presents studies of cardiorespiratory parameters of football players of the control (10 athletes) and experimental group (10 athletes) with the manifestation of postcoid symptoms, after the transfer of COVID-19 to a mild degree. Two weeks after recovery, all athletes for two months at home performed a complex of therapeutic physical education, which included exercises that stimulate respiratory processes. The experimental group, in addition, was offered hydrorehabilitation measures aimed at increasing tolerance to physical activity, activation of respiratory muscles. This technique included inspiratory training based on static and dynamic breathing exercises that improve pulmonary ventilation and blood circulation. At the stages before and after the rehabilitation, the parameters of the cardiovascular and respiratory systems were recorded. All studied athletes had a positive effect of rehabilitation exercises on cardiorespiratory parameters, an increase in the functional capabilities of the body. A comparative between-group analysis of cardiorespiratory patients at baseline showed no differences at baseline, confirming sample uniformity. After the rehabilitation, there were no differences in the parameters of heart rate, systolic and blood pressure. However, lower pulse pressure values in the experimental group showed a significant development of positive adaptation mechanisms of hemodynamics. In the group of football players who used hydrorehabilitation, there was an advantage of most respiratory parameters compared to the control group. There was a higher degree of oxygen saturation, indicators of the respiratory efficiency index, a more significant breath holding time for inhalation in the Stang sample and exhalation in the Genchi sample. In general, the implementation of rehabilitation measures contributes to the leveling of circulatory failure and respiratory performance in football players with postcoid syndrome. Hydrorehabilitation methods contribute to a more pronounced positive dynamics of the cardiorespiratory capabilities of the body and the manifestation of their adaptive properties. The obtained research results determine rehabilitation strategies aimed at restoring the capabilities and compensation of functional systems in athletes who have undergone mild coronavirus infection.
