The American Journal of Preventative Medicine (AJPM) put out a study called, "Associations of Physical Inactivity and COVID-19 Outcomes Among Subgroups."
Contrary to the actions of public health officials the world over, which resulted in closed gyms, banning of organized sports, and creating a sanitary housebound society of Uber Eaters, the benefits of physical activity acted as prophylactic against severe COVID-19 outcomes, even for people who had comorbidities which would exacerbate illnesses.
According to the study:
Of 194,191 adults with COVID-19 infection, 6.3% were hospitalized, 3.1% experienced a deterioration event, and 2.8% died within 90 days.
Dose‒response effects were strong; for example, patients in the some activity category had higher odds of hospitalization (OR=1.43; 95% CI=1.26, 1.63), deterioration (OR=1.83; 95% CI=1.49, 2.25), and death (OR=1.92; 95% CI=1.48, 2.49) than those in the always active category.
Results were generally consistent across sex, race and ethnicity, age, and BMI categories and for patients with cardiovascular disease or hypertension.
"There were protective associations of physical activity for adverse COVID-19 outcomes across demographic and clinical characteristics. Public health leaders should add physical activity to pandemic control strategies," the analysis concluded.
Fitness industry analysts report that up to 22% of North American gyms did not survive the pandemic's forced-closures at the hands of government.
