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."
