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.

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.

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