The researchers analyzed 16 beforehand printed research that appeared for associations between bodily exercise and COVID-19 outcomes. These research included greater than 1.8 million adults in all, and most relied on members self-reporting their train habits.

The paper doesn’t present proof that train is inflicting these results—solely that it’s linked to raised COVID-19 outcomes. There may very well be different explanations for the traits, reminiscent of variations in way of life, viral publicity, and socioeconomic standing between energetic and sedentary folks. Many of the included research had been additionally printed nicely earlier than Omicron grew to become dominant and when most individuals weren’t vaccinated, so it’s tough to generalize the findings to the current.
One different potential caveat: should you occur to be exercising subsequent to somebody who already has COVID-19, your exercise routine could not prevent from getting sick. A small research printed in Might discovered that somebody doing high-intensity train emits about 132 instances as many aerosols per minute as they do at relaxation—which is dangerous information in case your treadmill neighbor occurs to have the virus.
