Graded versus Intermittent Exercise Effects on Lymphocytes in Chronic Fatigue Syndrome.
Broadbent, Suzanne, Coutts, Rosanne·Medicine and science in sports and exercise·2016
This study tested whether two types of exercise programs—graded (gradually increasing intensity) and intermittent (alternating intense and easy periods)—could help improve immune system function in ME/CFS patients. Over 12 weeks, both exercise types led to increases in certain immune cells and improved fitness without making symptoms worse. Intermittent exercise appeared to work slightly better than graded exercise for boosting immune activation.
