简要总结
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.
详细描述
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.

研究组 & 干预措施
WB-EMS group
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.
干预措施: Whole-body electromyostimulation (WB-EMS) training (Other)
Control group
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.
干预措施: Supervised exercise without whole-body electromyostimulation (WB-EMS) (Behavioral)
结局指标
主要结局
Body Mass Index (BMI)
时间窗: Baseline and after the 16 weeks of the training intervention.
BMI calculated as weight (kg) divided by height squared (m²)
Body fat percentage
时间窗: Baseline and after the 16 weeks of the training intervention
Bodyfat percentage determined from four skinfold sites (biceps, triceps, subscapular, and supra-iliac) using a calibrated Harpenden Skinfold Caliper. Measurements expressed as %.
Waist circumference
时间窗: 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.
Hip circumference
时间窗: Baseline and after the 16 weeks of the training intervention
Measured at the widest point of the hips using a non-elastic tape measure. Measurements expressed in cm.
Total Cholesterol
时间窗: Baseline and after the 16 weeks of the training intervention.
Plasma total cholesterol concentration (mg/dL).
Triglycerides
时间窗: Baseline and after the 16 weeks of the training intervention
Plasma triglyceride concentration (mg/dL)
High-Density Lipoprotein (HDL) Cholesterol
时间窗: Baseline and after the 16 weeks of the training intervention
Plasma HDL cholesterol concentration (mg/dL)
