This paper reviews publications covering the delayed clinical and functional manifestations of SARS-CoV2 among athletes competing at national and international levels; we describe the prevalence of multiorgan failure associated with protracted COVID as registered in sportsmen and people not going in for sports. The review reports the results of a retrospective analysis of data yielded from clinical, instrumental and laboratory tests undertaken by the Russian national team athletes that had COVID-19. We highlight the most informative indicators that reflect the condition of sportsmen with protracted coronavirus infection course, define the approaches making resumption of active training safe and compile the list of the most significant criteria supporting admission to such training and competitions. Lastly, the paper presents the parameters subject to inclusion in the prognostic model (binary logistic regression) describing the dynamics of residual multiorgan failure in athletes, including minors, who have had COVID-19 or viral pneumonia of a different etiology.
