Objective of the study was to assess the morphofunctional state of the body of athletes who had previously undergone COVID-19.
Methods and structure of the study. A scientific examination of athletes in mid-mountain conditions was carried out between 3-6 days of training camps at an altitude of 1240 m in Kislovodsk, on Mount Small Saddle, in FSUE «Yug-Sport» in 87 highly qualified male athletes, age - 21.3 ±6.2 years. Athletes were divided into the main group - earlier, during the year, who had COVID-19 (n=42) and the control group - who did not have COVID-19 (n=45). Athletes of different sports were studied: the functional state of the cardiovascular and respiratory systems, heart rate variability, body composition.
Results and conclusions. The results of the study showed that athletes who had previously recovered from COVID-19 were characterized by greater age, height, lean body mass, and a stiffness index associated with blood pressure in large arteries. Men who have been ill with symptoms of varying severity differ from those who have been asymptomatic in lower blood saturation.
An analysis of the data from the standpoint of adaptation theory and systems theory led to the conclusion that, despite the seemingly favorable morphofunctional state of male athletes, it is characterized by an emergency transition process of adaptation, during which various diseases may exacerbate, which should be paid attention to by sports medicine physicians working with athletes and coaches.

Keywords: athletes, COVID-19, functional state, cardiorespiratory system, middle mountains.
