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

26 de junho de 2026 atualizado por: Murat Açık, Firat University

Effects of an Eight-Week Whole-Body Electromyostimulation and Diet Program on Body Composition, Cardiometabolic Markers, and the Myokines Irisin and Betatrophin in Women With Obesity: A Randomized Controlled Trial

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.

Descrição detalhada

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.

Armas e Intervenções

Grupo de Participantes / Braço
Intervenção / Tratamento
Comparador Ativo: 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.
Comportamental: Hypocaloric Diet
An individualized hypocaloric diet with a 500 kcal/day deficit calculated using the Mifflin-St. Jeor equation, prescribed to both study arms for 8 weeks.
Experimental: 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.
Comportamental: Hypocaloric Diet
An individualized hypocaloric diet with a 500 kcal/day deficit calculated using the Mifflin-St. Jeor equation, prescribed to both study arms for 8 weeks.
Dispositivo: Whole-Body Electromyostimulation (WB-EMS)
WB-EMS training was performed twice per week for 8 weeks, with 20-minute sessions using a full-body electrostimulation suit. Stimulation parameters: frequency 85 Hz, pulse width 350 µs, intermittent mode (4 s on / 4 s off), with simultaneous dynamic exercises.
