About this study
Official title: Effects of a 16-Week Whole-Body Electromyostimulation Program on Cardiometabolic Markers, Functional Capacity, and Quality of Life in Overweight/Obese Postmenopausal Women: A Randomized Controlled Trial
The goal of this randomized controlled trial is to investigate the effects of a 16-week whole-body electromyostimulation (WB-EMS) program on body composition, cardiometabolic health, functional capacity, quality of life, and satisfaction with life in overweight/obese postmenopausal women. The study will examine whether adding WB-EMS to a supervised exercise program results in greater improvements in these outcomes compared with the same exercise program performed without electrical stimulation.
Participants will be randomly allocated to either the WB-EMS group or the control group. Both groups will participate in a 16-week supervised exercise program consisting of two sessions per week, with at least 48 hours between consecutive sessions.

Participants in the WB-EMS group will perform supervised exercise sessions with whole-body electrical stimulation. WB-EMS will be delivered using bipolar electrical impulses at a frequency of 85 Hz and a pulse width of 350 μs, with an intermittent stimulation pattern of 4 seconds of stimulation followed by 4 seconds of rest. The exercise program will include dynamic resistance and functional exercises involving major muscle groups, including squats, lunges, upper-body pushing and pulling movements, and trunk exercises.
The control group will perform the same supervised exercise program without electrical stimulation. Exercise type, session duration, weekly frequency, intervention duration, supervision, and progression will be matched between groups to isolate the additional effects of WB-EMS.
Read the detailed description
This study is designed to investigate the effects of a 16-week whole-body electromyostimulation (WB-EMS) program on body composition, cardiometabolic markers, functional capacity, quality of life, and satisfaction with life in overweight/obese postmenopausal women. A total of 30 overweight/obese postmenopausal women will be randomly allocated to either the whole-body electromyostimulation (WB-EMS) group (n=15) or the control group (n=15). Participants in both groups will participate in a 16-week supervised exercise program consisting of two sessions per week, with at least 48 hours between consecutive sessions.
Participants in the WB-EMS group will perform 20-minute exercise sessions while receiving whole-body electrical stimulation. WB-EMS will be delivered using bipolar electrical impulses at a frequency of 85 Hz and a pulse width of 350 μs, with an intermittent stimulation pattern of 4 seconds of stimulation followed by 4 seconds of rest. During the sessions, participants will perform dynamic resistance and functional exercises involving major muscle groups, including squats, lunges, upper-body pushing and pulling movements, and trunk exercises.
The control group will perform the same supervised exercise program without electrical stimulation. Exercise type, session duration, weekly frequency, intervention duration, supervision, and progression will be matched between groups to isolate the additional effects of WB-EMS.
Outcomes will be assessed at baseline and after the 16-week intervention. The assessments will include body composition, systolic and diastolic blood pressure, resting heart rate, functional capacity assessed using the 6-minute walk test (6MWT), fasting blood glucose, and lipid profile [triglycerides (TG), total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), and low-density lipoprotein cholesterol (LDL-C)]. Quality of life and satisfaction with life will also be assessed using validated questionnaires.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Whole-body electromyostimulation (WB-EMS) trainingOther
Participants will complete a 16-week supervised exercise program consisting of two sessions per week, with at least 48 hours between consecutive sessions. The WB-EMS group will perform 20-minute sessions while receiving bipolar electrical stimulation at 85 Hz with a pulse width of 350 μs, using an intermittent 4-second stimulation/4-second rest pattern. Exercises will include squats, lunges, upper-body pushing and pulling movements, and trunk exercises targeting major muscle groups. Stimulation intensity will be individually adjusted according to participants' tolerance, with a target perceived intensity of approximately 5-7 on a 0-10 scale.
Supervised exercise without whole-body electromyostimulation (WB-EMS)Behavioural
The control group will perform the same exercise program without electrical stimulation. Exercise type, session duration, weekly frequency, intervention duration, supervision, and progression will be matched between groups to isolate the additional effect of WB-EMS.
| Study group | Role | What they receive |
|---|---|---|
| WB-EMS group | Experimental | Participants will participate in a 16-week supervised exercise program consisting of two sessions per week, with at least 48 hours between consecutive sessions. Each session will include 20 minutes of whole-body electromyostimulation (WB-EMS) combined with dynamic resistance and functional exercises involving major muscle groups, including squats, lunges, upper-body pushing and pulling movements, and trunk exercises. WB-EMS will be delivered using bipolar electrical impulses at a frequency of 85 Hz and a pulse width of 350 μs, with an intermittent stimulation pattern of 4 seconds of stimulation followed by 4 seconds of rest. Exercise type, session duration, weekly frequency, supervision, and progression will be standardized throughout the intervention. Receives: Other: Whole-body electromyostimulation (WB-EMS) training |
| Control group | Active comparator | Participants will participate in the same 16-week supervised exercise program consisting of two sessions per week, with at least 48 hours between consecutive sessions. Participants will perform the same dynamic resistance and functional exercises as the WB-EMS group, including squats, lunges, upper-body pushing and pulling movements, and trunk exercises, but without electrical stimulation. Exercise type, session duration, weekly frequency, supervision, and progression will be matched to those of the WB-EMS group. Receives: Behavioral: Supervised exercise without whole-body electromyostimulation (WB-EMS) |
What is being measured
The primary outcome is the main question the study is designed to answer.

BMI calculated as weight (kg) divided by height squared (m²)
Measured: Baseline and after the 16 weeks of the training intervention.

Measured at the narrowest point between the rib cage and iliac crest using a non-elastic tape measure. Measurements expressed in cm.
Measured: Baseline and after the 16 weeks of the training intervention.]
Hip circumference

Measured: Baseline and after the 16 weeks of the training intervention
Total Cholesterol

Menopause-specific quality-of-life score (MENQOL)
Menopause-specific quality of life will be assessed using the validated Arabic version of the 29-item Menopause-Specific Quality of Life Questionnaire (MENQOL). Higher scores indicate poorer quality of life.
Measured: Baseline and after the 16 weeks of the training intervention

Fasting glucose
Fasting plasma glucose concentration (mmol/L).
Measured: Baseline and after the 16 weeks of the training intervention
Blood Pressure (Systolic and Diastolic)
Measured using an automated arm cuff (Omron BP652)

Measured using automated device (Omron BP652)
Measured: Baseline and after the 16 weeks of the training intervention
Satisfaction with life
