The US Centers for Disease Control and Prevention (CDC) has identified risk factors for severe COVID-19, including advanced age, sex (male) and the presence of underlying comorbidities, such as diabetes, obesity and cardiovascular disease. However, there are no data regarding the effect of regular physical activity (PA) on COVID-19 outcomes, even though a lack of PA is a well-documented underlying risk factor for multiple chronic diseases, including those associated with severe COVID-19.
