Retrospective 71 hospitalized COVID-19 patients in Iran, showing faster recovery with a history of moderate to high physical exercise.
Exercise was assessed during the last seven days when patients may already have had COVID-19 symptoms. Patients with higher severity may have been less likely to exercise, leading to confounding by indication

Background: Different degrees of disorders are reported in the respiratory, physical, and psychological functions of patients with
corona virus disease 2019 (COVID-19). With the experience of improved and discharged COVID-19 patients, physical activity and
sports are considered as one of the factors in controlling chronic mental and physical illnesses.
Objectives: This study was aimed at investigating the impact of the level of physical activity on some important clinical parameters
Methods: Overall, 71 patients with COVID-19 under the age of 65 years admitted to the hospital with positive PCR were included in
the study. Based on Beck’s questionnaire, patients were divided into two groups of (1) low and (2) moderate to high physical activity.
The duration of hospitalization and some important clinical tests were examined at the time of hospitalization and discharge. The
patients were then monitored until discharge.
Results: Statistical analyses showed that people with moderate to high physical activity were discharged earlier than the group with
low physical activity (P < 0.01). Moreover, patients with moderate to high physical activity had lower erythrocyte sedimentation rate
than the group with low physical activity at discharge (P = 0.01).
Conclusions: Moderate to high physical activity can significantly reduce the length of hospitalization by improving the immune
system to fight COVID-19. However, the factors that can be examined in expressing the reason for this finding need further studies.

More than 55 million confirmed cases of corona virus
disease 2019 (COVID-19) have been reported so far. COVID19 as a novel coronavirus infection can cause flu-like symptoms, such as fever (89%), cough (68%), fatigue (38%), sputum production (34%), dyspnea (19%), and pneumonia (15). Severe acute respiratory syndrome (SARS) following
COVID-19 is an emerged respiratory disease that exacerbates the rate of mortality (2). Overall, the rate of mortality
in this disease is reported 3 - 5%, which is severely higher
than the rate of mortality of flu disease (0.1%). Therefore,
the identification of preventive factors for decreasing the
respiratory symptoms and the rate of mortality following
COVID-19 is critical.
There is evidence that having regular physical activity
and daily exercise is one of the main factors of control-
ling chronic diseases (6-8). Doing regular exercise can improve the cardiovascular system, respiratory capacity, and
immune system (2, 6, 9). In addition, some studies reported that the rate of..
