Descrizione dettagliata
This study was a randomized controlled trial (RCT) designed to investigate 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 one of two groups: (1) Diet-only group (control): received a hypocaloric diet prescription without exercise training; (2) WB-EMS + Diet group (intervention): received the same hypocaloric diet plus WB-EMS training sessions conducted twice weekly (20-25 minutes per session) over 8 weeks.
Body composition assessments included body weight, BMI, body fat percentage, fat mass, fat-free mass, and waist circumference, measured using multifrequency bioelectrical impedance analysis (InBody 270). Cardiometabolic markers assessed included fasting blood glucose, serum insulin, HOMA-IR, HbA1c, total cholesterol, LDL cholesterol, HDL cholesterol, triglycerides, blood pressure, and C-reactive protein (CRP). Serum irisin and betatrophin concentrations were measured at baseline and post-intervention using ELISA.
The primary aim was to evaluate whether WB-EMS combined with dietary restriction provides additional metabolic and myokine-related benefits beyond those achieved by dietary restriction alone in obese women.

Comparatore attivo: Diet Only
Participants received an 8-week individualized hypocaloric diet program only.
The diet was prescribed based on the Mifflin-St.
Jeor equation with a 500 kcal/day deficit.

Sperimentale: Diet + WB-EMS
Participants received an 8-week individualized hypocaloric diet program combined with whole-body electromyostimulation (WB-EMS) training.
The diet was prescribed based on the Mifflin-St.
Jeor equation with a 500 kcal/day deficit.
WB-EMS sessions were performed twice per week for 20 minutes using a full-body electrostimulation suit.
