This peer-reviewed study provides physiological evidence for post-exertional malaise (PEM) in long COVID, showing that patients' skeletal muscle structure and metabolic function measurably worsen after exercise-induced PEM. The findings point to mechanisms such as exercise-induced myopathy and amyloid-containing deposits in muscle tissue, helping explain why exertion triggers symptom crashes in long COVID patients.
