WB-EMS and Diet Effects on Body Composition, Cardiometabolic Markers, and Myokines in Obese Women

This randomized controlled trial investigated the effects of an 8-week whole-body electromyostimulation (WB-EMS) combined with a hypocaloric diet on body composition, cardiometabolic markers, and serum levels of the myokines irisin and betatrophin (ANGPTL8) in women with obesity. Participants were randomly assigned to either a diet-only group or a diet plus WB-EMS group. WB-EMS sessions were conducted twice weekly (20-25 minutes per session) over 8 weeks. The primary outcomes included BMI, body fat percentage, lean body mass, fasting blood glucose, insulin, HOMA-IR, HbA1c, lipid profile, CRP, and serum irisin and betatrophin concentrations. The study aimed to evaluate whether WB-EMS adds metabolic and myokine-related benefits beyond those achieved by dietary restriction alone in obese women.
