Whole-body Electromyostimulation Versus Conventional Low-volume Strength Training in Overweight Individuals (EKAM)

October 15, 2018 updated by: University of Erlangen-Nürnberg Medical School

Comparison of the Effects of Whole-body Electromyostimulation Versus Conventional Low-volume Strength Training in Overweight Individuals at Increased Cardiometabolic Risk

The main purpose of this study is to compare the effects of whole-body electromyostimulation versus a conventional low-volume strength-training program, each combined with an individualized, weight-reducing diet, on the cardiometabolic risk profile, muscle strength, body composition, inflammatory markers and subjective health outcomes in overweight individuals at increased cardiometabolic risk.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Metabolic Syndrome Z-Score (MetS-Z-Score)
Time Frame: 12 weeks (baseline to 12 week follow-up assessment)
MetS-Z-Score will be calculated from each individual's measures of waist circumference, mean arterial blood pressure, triglycerides, and HDL-cholesterol, based on equations specific to sex.
12 weeks (baseline to 12 week follow-up assessment)

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Muscle strength
Time Frame: 12 weeks (baseline to 12 week follow-up assessment)
Muscle strength of the five major muscle groups (chest, upper back, lower back, abdominals, legs) will be assessed by using specific strength-training devices (Butterfly, Pull-down, Hyperextension, Abdominal Crunch, Leg-Press)
12 weeks (baseline to 12 week follow-up assessment)
Body Composition
Time Frame: 12 weeks (baseline to 12 week follow-up assessment)
Muscle mass, fat mass and body water will be measured by Bioelectrical Impedance Analysis (BIA)
12 weeks (baseline to 12 week follow-up assessment)
Cardiorespiratory Fitness (CRF)
Time Frame: 12 weeks (baseline to 12 week follow-up assessment)
CRF will be assessed by measuring Maximum Oxygen uptake (VO2max)
12 weeks (baseline to 12 week follow-up assessment)
Inflammation status
Time Frame: 12 weeks (baseline to 12 week follow-up assessment)
Inflammation will be assessed by measuring Levels of CRP and inflammatory cytokines and other inflammatory blood markers
12 weeks (baseline to 12 week follow-up assessment)
Health-related quality of life
Time Frame: 12 weeks (baseline to 12 week follow-up assessment)
Health-related quality of life will be assessed by using the standardized and validated EQ-5D-5L Questionnaire
