Exercise Pathophysiology in Myalgic Encephalomyelitis/Chronic Fatigue Syndrome and Postacute Sequelae of SARS-CoV-2: More in Common Than Not?
Joseph, Phillip, Singh, Inderjit, Oliveira, Rudolf et al.·Chest·2023
This review compares how the body responds to exercise in people with long COVID (PASC) and ME/CFS, two conditions that share similar symptoms like extreme tiredness and worsening symptoms after activity. Researchers found that both conditions show similar abnormalities in heart function, blood flow, and breathing during exercise that go beyond simple deconditioning or being out of shape. These shared patterns suggest both conditions may involve similar underlying biological problems, which could help doctors develop better tests and treatments.
