This study describes a small group of long COVID patients whose symptoms improved or went away when they exercised regularly. The researchers suggest that exercise might be a helpful treatment strategy for long COVID, since the condition may partly involve the heart and muscles becoming deconditioned (weak from lack of use).
This study is relevant to ME/CFS patients because post-exertional malaise (PEM)—worsening after activity—is a core symptom in both ME/CFS and some long COVID cases. Understanding how exercise affects long COVID could inform treatment approaches, though findings must be carefully interpreted given ME/CFS pathophysiology differs from simple deconditioning.
This case series does not prove that exercise is safe or effective for all long COVID or ME/CFS patients, nor does it establish causation—symptom improvement could reflect natural recovery, placebo effect, or other factors. The study cannot rule out exercise-induced harm in patients with post-exertional malaise, a concern highly relevant to ME/CFS populations.
About the PEM badge: “PEM required” means post-exertional malaise was an explicit required diagnostic criterion for participant inclusion in this study — not that PEM was studied, observed, or discussed. Studies using criteria that do not require PEM (e.g. Fukuda, Oxford) are tagged “PEM not required”. How the atlas works →
