Abstract

Background: The Tokyo Olympic games were the only games postponed for a year in peacetime, which will be remembered as the COVID-19 Olympics. No data are currently available on the effect on athlete's performance.

Aim: To examine the Italian Olympic athletes who have undergone the return to play (RTP) protocol after COVID-19 and their Olympic results.

Methods: 642 Potential Olympics (PO) athletes competing in 19 summer sport disciplines were evaluated through a preparticipation screening protocol and, when necessary, with the RTP protocol. The protocol comprised blood tests, 12-lead resting ECG, transthoracic echocardiogram, cardiopulmonary exercise test, 24-hour Holter-ECG monitoring and cardiovascular MR based on clinical indication.

Results: Of the 642 PO athletes evaluated, 384 participated at the Olympic Games, 254 being excluded for athletic reasons. 120 athletes of the total cohort of 642 PO were affected by COVID-19. They were evaluated with the RTP protocol before resuming physical activity after a mean detraining period of 30±13 days. Of them, 100 were selected for Olympic Games participation, 16 were excluded for athletic reasons and 4 were due to RTP results (2 for COVID-19-related myocarditis, 1 for pericarditis and 1 for complex ventricular arrhythmias). Among athletes with a history of COVID-19 allowed to resume physical activity after the RTP and selected for the Olympic Games, no one had abnormalities in cardiopulmonary exercise test parameters, and 28 became medal winners with 6 gold, 6 silver and 19 bronze medals.

Conclusions: Among athletes with COVID-19, there is a low prevalence of cardiac sequelae. For those athletes allowed to resume physical activity after the RTP evaluation, the infection and the forced period of inactivity didn't have a negative impact on athletic performance.
