Abstract

COVID-19 quarantine restrictions have reduced total physical activity (PA) throughout the world globally by an average of 45–50%. At the same time, PA provides benefits directly related to reducing morbidity and mortality from coronavirus disease. Comparatively to inactive individuals, physically active individuals had lower risks of SARS-CoV-2 infection (adjusted relative risk (aRR) 0.85; 95% confidence interval (CI): 0.72–0.96) and severe COVID-19 (aRR 0.42; 95% CI: 0.19–0.91) and associated death (aRR 0.24; 95% CI: 0.05–0.99). Physical exercises help to preserve a healthy weight, promote a healthier diet, improve mental health, immune function, and have antioxidant effect. In addition, they may enhance the efficacy and immunogenicity of vaccines against SARS-CoV-2: for example, in physically active individuals comparatively to inactive individuals, the seroconversion rate of total anti-SARS-CoV-2 S1/S2 IgG increases by 1.6 times (95% CI: 1.1–2.4). To motivate people to exercise, it is necessary to use tele-exercise programs, home gym strategies and exergaming to reduce future risks in case of new “waves” of COVID-19.
