The Effect of Aerobic Exercise on Immune Biomarkers and Symptoms Severity and Progression in Patients With COVID-19: A Pilot Randomized Control Trial

Participants in the exercise group performed a two weeks aerobic exercise program. The exercise program consisted of walking/running on a treadmill or bicycling on a stationary bicycle. Each session is composed of five-minute warm-up slow walking or bicycling. Then the main intervention which composed of thirty-minutes of moderate-intensity aerobic exercises (walking/running or bicycling). Lastly, a five-minute of cool-down exercises (walking/running or bicycling). The exercise intensity was 60-75% of the predicted MHR (calculated as MHR=210-age).
