What this Trial Is About
Researchers are evaluating the effects of a supervised whole-body high-intensity interval training (WB-HIIT) program on physical fitness and health outcomes in adults who are overweight or obese. This study aims to understand whether WB-HIIT, a time-efficient and equipment-free exercise using body-weight movements performed at high intensity, can improve cardiorespiratory fitness, muscular strength, body composition, and metabolic health in adults aged 18 to 55 years with a BMI between 25 and 35 kg/m². Participants are divided into two groups: one group undergoes a 10-week supervised WB-HIIT program with 2 to 3 sessions per week, each lasting 35 to 50 minutes and including 8 to 12 exercises such as squats, lunges, and mountain climbers performed in intervals with controlled recovery. The sessions are led by trained exercise professionals who monitor heart rate and perceived exertion to adjust intensity and progression. The control group maintains their usual lifestyle without structured exercise but completes the same assessments. Throughout the study, participants undergo comprehensive evaluations before and after the intervention, including body composition analysis by DXA, blood tests for metabolic markers, muscle strength testing, and fitness assessments such as a graded treadmill test to measure peak oxygen consumption (VO₂peak) and functional tests like chair-stand, arm-curl, and 6-minute walk tests. Dietary intake and physical activity levels are also recorded. The study measures changes in VO₂peak and muscle strength as primary outcomes, with additional assessments of body composition, metabolic health, and functional capacity. The total participation duration is approximately 10 weeks with evaluations at baseline and after the last training session.

Outpatient Treatment
Duration - 10 weeks
Participants in the intervention group complete a supervised whole-body high-intensity interval training (WB-HIIT) program consisting of 2 to 3 sessions per week for 10 weeks. Each session includes 8 to 12 body-weight exercises performed at high intensity with recovery intervals. Progression is achieved by adjusting exercise complexity, sets, and work-to-rest ratio. Participants in the control group maintain their usual lifestyle without structured exercise training.
2 to 3 sessions per week (in-person)
Post-intervention Assessment
Duration - 1 week
Participants undergo comprehensive evaluations including cardiorespiratory fitness, muscular strength and endurance, body composition, functional performance, blood biomarkers, physical activity, and dietary intake. These assessments occur within 72 hours after the last training session or equivalent time for control participants.
