Effects of Concurrent HIIT and WB-EMS Exercise on the Cardiometabolic Risk Profile in Obese Individuals

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.

Conditions

• Overweight and Obesity
• Metabolic Syndrome

Interventions

OTHER

HIIT + WB-EMS

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 + CST

12-week supervised exercise program consisting of ergometer-based high-intensity interval training (HIIT) and conventional low-volume strength training(CST). 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.
