Brief summary
The main purpose of this study is to compare the impact of concurrent high-intensity interval training (HIIT) and whole-body electromyostimulation exercise (WB-EMS) or low-volume conventional strength training (CST) on the cardiometabolic risk profile, overall physical fitness (cardiorespiratory fitness and muscular strength), body composition, inflammatory markers and subjective health outcomes after a 12-week intervention trial in overweight individuals at increased cardiometabolic risk. Furthermore, this study aims to investigate the influence of intra-session exercise order on all outcomes.
Interventions
12-week supervised exercise program consisting of ergometer-based high-intensity interval training (HIIT) and whole-body electromyostimulation (WB-EMS). HIIT: 5x1 min at 85-95% HRmax divided by low-intensity recovery periods. WB-EMS: Simulanteous stimulation of all major muscle groups with dedicated individual intensity. 2 exercise sessions per week. Order of application: HIIT - WB-EMS. Additionally, participants receive individualized nutritional counseling.

HIIT: 5x1 min at 85-95% HRmax divided by low-intensity recovery periods. CST: Conventional 1-set strength training using weight machines to train all major muscle groups with an individual intensity corresponding to 70-80% of one repetition maximum. 2 exercise sessions per week. Order of application: HIIT - CST. Additionally, participants receive individualized nutritional counseling.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change in Metabolic Syndrome Z-Score (MetS-Z-Score). | 12 weeks | 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. |
| Change in overall Physical Fitness Score (PFS) | 12 weeks | PFS is calculated from VO2max and 1 Repmax values of 5 major muscle Groups. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Change in HOMA-IR | 12 week | Insulin resistance will be estimated using homeostasis model assessment index (HOMA) |
| Change Inflammation status | 12 weeks | Inflammation will be assessed by measuring levels of inflammatory blood markers (CRP, inflammatory cytokines) |
| Change in Perceived stress | 12 weeks | Perceived stress will be assessed by using the standardized and validated Perceived Stress Questionnaire (PSQ) |
| Change in Pain scores | 12 weeks | Pain scores will be assessed by using the standardized and validated Chronic Pain Grade Questionnaire (CPGQ) |
| Change Subjective work ability | 12 weeks | Subjective work ability will be assessed by using the standardized and validated Work Ability Index Questionnaire (WAI) |
| Change in Health-related quality of life | 12 weeks | Health-related quality of life will be assessed by using the standardized and validated EQ-5D-5L Questionnaire |
| Change in Body Composition | 12 weeks | Muscle mass, fat mass and body water will be measured by Bioelectrical Impedance Analysis (BIA) |
