Summary

Obesity is associated with impaired vascular function, metabolic dysfunction, and reduced physical fitness, which increase cardiovascular disease risk. This randomized controlled trial aims to investigate the effects of a 12-week home-based circuit training program using light-to-moderate resistance on vascular health, body composition, metabolic function, resting metabolic rate, substrate oxidation, physical activity, and physical fitness in adults with obesity. Participants will be randomly assigned to either a home-based circuit training group or a control group maintaining usual daily activities. The findings may support the use of home-based exercise as a practical and time-efficient strategy for obesity management and cardiovascular risk reduction.

Home-Based Circuit Training

Participants will perform a 12-week home-based circuit training program three times per week. Each session includes warm-up, circuit-based exercises targeting major muscle groups, and cool-down activities. The intervention is designed to improve vascular and metabolic health in adults with obesity. The training program consisted of two phases: phase 1 (weeks 1-6) and phase 2 (weeks 7-12). During phase 1, participants performed resistance exercises at an intensity of 65-70% of one-repetition maximum (1RM). Each exercise consisted of 12 repetitions, with a 1-minute rest between exercises. The lifting tempo was maintained at 2:2 (concentric: eccentric). Participants completed 8 exercises per circuit for a total of 3 circuits, with a 2-minute rest between circuits. During phase 2, the intensity was increased to 70-75% of 1RM, while maintaining 12 repetitions per exercise. The rest interval between exercises was reduced to 30 seconds, with the same lifting tempo (2:2). Participants complete
