Among Covid-19 patients, a lack of exercise is linked to more severe symptoms and a higher risk of death, according to a study covering nearly 50,000 people who were infected with the virus.
People physically inactive for at least two years before the pandemic were more likely to be hospitalised, to require intensive care, and to die, researchers reported in the British Journal of Sports Medicine.
As a risk factor for serious Covid disease, physical inactivity was surpassed only by advanced age and a history of organ transplant, the study found.
Indeed, compared to other modifiable risk factors such as smoking, obesity or hypertension, “physical inactivity was the strongest risk factor across all outcomes,” the authors concluded.
Covid-19 has killed over 2.97M people and infected nearly 138M others globally.
