ABSTRACT
In this viewpoint we make specic recommendations that
can assist and make the return to sport/exercise as safe
as possible for all those impacted – from the recreational
athlete to the elite athlete. 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 difcult time. The present viewpoint provides
practical and medical recommendations on the resumption
to sport process.
BACKGROUND
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 lock-
down 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 lock-
down was gradually lifted. Team sports have
commenced reintroducing their training
routines in groups, and the Bundesliga reac-
tivated 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 espe-
cially 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 symp-
toms to be considered to make the return to
sport as safely as possible, consult Carmody
et al3 and Nieß et al.4 The present viewpoint
provides practical and medical recommenda-
tions on the resumption to sport process.
GROUP IDENTIFICATION
During the resumption to sport process, the
following groups must be distinguished (indi-
viduals 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 se-
vere acute respiratory syndrome coronavi-
rus 2 (SARS- CoV-2).
2. Individuals with a positive SARS- CoV-2 test
without any COVID-19 symptoms but iso-
lating at home (quarantine) under close
medical observation (telephonic or video).
3. Individuals who experienced COVID-19
with mild symptoms, only needing outpa-
tient treatment and quarantine for 14 days.
4. Individuals with moderate symptoms but
had inpatient treatment due to an in-
creased risk derived from pre- existing con-
ditions (eg, asthma, diabetes).
5. Individuals with severe symptoms, inpa-
tient treatment, including intensive care
without artificial respiration.

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 cardi-
ologist, if suspicious findings of the pulmonary and/or
cardiovascular systems arise.
RECOMMENDATIONS FOR INDIVIDUAL GROUPS
Group 1
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 evalu-
ated 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 lock-
down,6 and exercise testing must be performed according
to the latest COVID-19/SARS- CoV-2 health and safety
regulations.
Group 2
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.
Group 3
Resumption after a quarantine period of 2 weeks and
strict social distancing for another 2 weeks.
A medical examination by a sport and exercise medi-
cine 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.
Group 4
Same procedure as for group 3 but including compulsory
ergometry with blood gas analysis and/or spiroergom-
etry.3–5 10 Chest X- ray examination and depending on
the findings obtained during the inpatient stay, high-
resolution CT of the thorax in the most severe cases always
in consultation with a lung specialist. Cardiac examina-
tions 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 (myocar-
ditis) involvement.
Groups 5 and 6
Following SARS- CoV-2 discharge, rehabilitation is recom-
mended. 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 stipu-
lated (eg, National/International Sports Federation,
Government).
CONCLUSIONS
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 multidisci-
plinary team), coaches and training specialists. After a
contact ban, an athlete should be provided with recom-
mendations 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.
