Physical activity is difficult for patients affected by Coronavirus. However, sticking to the physical activity recommendations was strongly linked with reduced risk for severe COVID-19 consequences among the affected individuals above 18 years of age, Conclusions to this effect have recently been published in a study in the British Journal of Sport Medicine

A study was performed by US researchers to compare hospitalisation and mortality rates, as well as intensive care unit (ICU) admissions for patients who were physically inactive, engaged in moderate activity, or were completely following the physical activity recommendations before the COVID-19 pandemic, based on the information obtained through the electronic health record (EHR) of the patients.

The researchers selected 48,440 adult COVID-19 positive patients between January 1, 2020 to October 21, 2020, who showcased at least three exercise vital sign measurements from March 19, 2018 to March 18, 2020. They linked each patient's self-reported physical activity category (consistently inactive=0–10?min/week, some activity=11–149?min/week, consistently meeting guidelines=150+ min/week) to the risk of hospitalisation, ICU admission and death after COVID-19 diagnosis.

The researchers then conducted multivariable logistic regression controlling for demographics and known risk factors to assess whether inactivity was associated with COVID-19 outcomes. The authors found the following:

Patients with COVID-19 who were consistently inactive had a greater risk of hospitalisation,
• Inactivity patients also are 1.73 times higher likely have admission to the ICU (OR 1.73; 95% CI 1.18 to 2.55)
• Death risk was 2.49 times higher in inactive (OR 2.49; 95% CI 1.33 to 4.67) due to COVID-19 than patients who were consistently meeting physical activity guidelines.

The study also found that even some activity was better than inactivity. Patients who were consistently inactive also had a greater risk of hospitalisation, admission to the ICU and death due to COVID-19 than patients who were doing some physical activity. "This was a first of its kind study to show the significance of physical activity as well as its role as a crucial risk factor in severe COVID-19 outcomes," noted the authors in their study.

This study concluded that though fulfilling the US Physical Activity Guidelines provided significant benefit in COVID-19 outcomes, performing some activity also reduced the risks of progressing to severe COVID-19 outcomes, when compared to completely inactive patients.
