Home-Based Circuit Training in Adults With Obesity
Sponsor: Chulalongkorn University
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
