We acknowledge that there are varying rules and regulations around the world, not to mention the varying philosophies and numerous schools of thought as it relates to return to sport/exercise and we have been cognisant of this in our recommendations. Despite the varying rules and circumstances around the world, we believe it is essential to provide some helpful and consistent guidance for return to training and sport for sport and exercise physicians around the world at this most difficult time. The present viewpoint provides practical and medical recommendations on the resumption to sport process.

The present viewpoint provides practical and medical recommendations on the resumption to sport process. The COVID-19 pandemic and the restrictive measures adopted internationally in order to contain the virus has led to a disruption of organised sport at all levels. During the lockdown period, outdoor exercise was forbidden or partly restricted in some cases without access to sports facilities including gyms or sports centres. As the number of infections and hospitalisations decreased, the strict lockdown was gradually lifted. Team sports have commenced reintroducing their training routines in groups, and the Bundesliga reactivated the professional league behind closed doors on 16 May 2020 despite serious concerns raised by some in the scientific community. 1 Additional sporting competitions such as boxing, Ultimate Fighting Championship and Formula 1 are also scheduled to resume. 2 It is worth noting that social distancing is possible in some sports (eg, tennis, swimming, athletics and golf) whereas this is not always possible in other cases (eg, football, rugby, basketball, cycling and boxing), and careful measures of hygiene and control are especially needed for these more at risk sports to regulate the safety of sport resumption and to avoid possible infections. For more thorough information about the risk factors and symptoms to be considered to make the return to sport as safely as possible, consult Carmody et al 3 and Nieß et al. 4 The present viewpoint provides practical and medical recommendations on the resumption to sport process. During the resumption to sport process, the following groups must be distinguished (individuals below refer to both leisure time and professional athletes or persons starting new with regular physical activities). This group classification is a more developed version of that recently published by Phelan et al. 5 : 1. Individuals without symptoms and signs that never have been tested positive for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). without any COVID-19 symptoms but isolating at home (quarantine) under close medical observation (telephonic or video). with mild symptoms, only needing outpatient treatment and quarantine for 14 days. 4. Individuals with moderate symptoms but had inpatient treatment due to an increased risk derived from pre-existing conditions (eg, asthma, diabetes). 5. Individuals with severe symptoms, inpatient treatment, including intensive care without artificial respiration. Open access 6. Individuals with severe symptoms, inpatient treatment in intensive care and on artificial respiration. It is imperative that a medical examination is performed in cooperation with a respiratory physician and/or cardiologist, if suspicious findings of the pulmonary and/or cardiovascular systems arise. In individuals without symptoms and signs of COVID-19 and without any pre-existing medical condition(s), risk stratification to safely resume to sport has to be evaluated through questionnaires compiling data related to personal and medical history, close contact with people with positive SARS-CoV-2 test, or contact with people of high risk of having been infected without being tested positive, or in so called hotspots. The individual has to confirm being free of any symptoms and this must be documented. Exercise testing is likely to be necessary in some sports due to the expected detraining after lockdown, 6 and exercise testing must be performed according to the latest COVID-19/SARS-CoV-2 health and safety regulations. Resumption after 14 days quarantine. Examinations ought to include medical history, physical examination, 12-channel ECG, lung function assessment with typical respiratory signs and symptoms, and ECG stress test. 5 7-9 Echocardiography if clinically indicated. Resumption after a quarantine period of 2 weeks and strict social distancing for another 2 weeks. A medical examination by a sport and exercise medicine physician with medical history, physical examination, blood test focused on critical markers (eg, C-reactive protein, high sensitivity troponin-I, natriuretic peptides), and resting ECG (eg, changes of Q-wave, ST-stretch, T-wave). 8 Additional lung function assessment and stress test with ECG, blood gas analysis and spiroergometry as well as echocardiography are recommended if symptoms have involved respiratory or cardiac impairment. Return to regular sport is possible 3-4 weeks after beginning of the symptoms under medical surveillance for 6 months after return to sport if any symptoms are present but not limiting return to sport. Same procedure as for group 3 but including compulsory ergometry with blood gas analysis and/or spiroergometry. 3-5 10 Chest X-ray examination and depending on the findings obtained during the inpatient stay, highresolution CT of the thorax in the most severe cases always in consultation with a lung specialist. Cardiac examinations depending on medical history, symptoms and signs, cardio-MRI after consultation with a cardiologist. Return to sport will vary from 2 to 6 months depending on the severity of respiratory (lung) and/or cardiac (myocarditis) involvement. Following SARS-CoV-2 discharge, rehabilitation is recommended. A complete pulmonary and cardiological examination is necessary ('cardiac markers' such as high sensitivity troponin-I or natriuretic peptides) including resting ECG, lung function, echocardiography, stress test with ECG and blood gas analysis. 8 10-13 Return to sport will be after several months depending on the severity and completeness of recovery. Depending on previous findings in heart rate, CT of the thorax and cardiac MRI examination in consultation with a respiratory physician and cardiologist, hospital discharge can take place. A final medical check and sports statement is mandatory. Resumption of sport can occur 10-14 days after complete recovery from SARS CoV-2 infection for athletes included in groups 1 and 2. In patients with more severe organ involvement, pneumonia, myocarditis or neurological signs, an individualised plan is necessary. 4 5 Testing for SARS CoV-2 can be carried out to support a return to play decision but is not essential unless stipulated (eg, National/International Sports Federation, Government). An adequate assessment of the resumption of sporting activity is based on a case-by-case decision that must consider the individual situation of the athlete including pre-existing conditions, the type of sport and the risk of infection from other athletes (eg, increased risk in contact/team sports). The recommendation to return to play will be based on the results of the examination and individual assessment in consultation with the sport and exercise medicine physician, specialists in pulmonary medicine and sport cardiology (or extended multidisciplinary team), coaches and training specialists. After a contact ban, an athlete should be provided with recommendations on sports resumption that are in accordance with national and regional guidelines. After a longer period of interruption in sport caused by more severe health issues, increases in training should be gradual and individualised by monitoring signs and symptoms of the health issue.
