Intermittent and graded exercise effects on NK cell degranulation markers LAMP-1/LAMP-2 and CD8+CD38+ in chronic fatigue syndrome/myalgic encephalomyelitis.
Broadbent, Suzanne, Coutts, Rosanne·Physiological reports·2017
This study tested whether two types of exercise programs could help improve immune system function in ME/CFS patients. Twenty-four ME/CFS patients were assigned to either graded exercise, intermittent exercise, or usual care, and researchers measured specific immune cells before and after 12 weeks. Both exercise programs increased markers of natural killer cell activity without making symptoms worse, and improved patients' exercise capacity.
