¹All F-NRL athletes underwent ECG at inclusion. The ECG was compared to an ECG performed during the previous year. For COVID(+)_incident F-NRL players, the post-COVID ECG was compared to pre-COVID ECG. All sport students of the University of Bordeaux underwent an inclusion ECG
²COVID(+)_prevalent and COVID(+)_incident athletes underwent echocardiography at the end of the isolation period. Any COVID(+) prevalent student athletes (history of positive SARS-CoV-2 PCR in the previous 6 months and/or positive serology at inclusion) underwent echocardiography
³All COVID(+) athletes underwent stress testing. ⁴CMR was performed in 130 athletes [102 COVID(+) and 28 COVID(−)]
