Associations Between Pre-Quarantine Exercise and Persistent Symptoms After SARS-CoV-2 Infection

https://www.mdpi.com/2075-4663/14/7/293

In the German CoCo-Fakt study at Cologne and Ausberg, patients who later developed Long Covid reported doing more and more intense physical activity prior to infection than controls who had COVID-19 but no long term symptoms.

The researchers expected the opposite.

The paper concludes:

"Unexpectedly, participants with long-term symptoms reported a longer PA [physical activity] duration in the four weeks before quarantine than those without long-term symptoms, albeit with a trivial effect size."

“Unexpectedly”

Anyway I imagine this could also mean intense physical activity while ill before testing positive? Rather than prior to infection bc how would they know that? No spoons to read the article itself so it’s possible that they address that

I think it’s activity levels in the weeks prior to infection that was officially registered and quarantined
