Abstract
This study examines how different intensity resistance exercises impact fat, energy intake, and appetite regulation in overweight and obese female college students in Jiangsu Province, China. This study used a randomized controlled trial (RCT) design that investigates resistance training intensity-target result causation. The study determines the impact of High-Intensity Interval Training (HIIT) and Moderate-Intensity Resistance Training (MIRT) on body composition, fat level/body composition, and muscle mass them. In Jiangsu Province, China, 515 overweight and obese female college students aged 18–25 were sampled. Intervention groups were assigned randomly to campus recruits based on demographic and anthropometric. This study demonstrated significant correlations between resistance training intensity, body composition, diet, and appetite regulation in overweight and obese colleagues. MIRT and HIIT outperformed Control in weight loss and diet and used valid measures like DEXA (Dual-Energy X-ray Absorptiometry), blood tests and food diaries to regulate appetite hormones. Increased protein and muscle mass minimize resistance exercise intensity-metabolic consequences. The study analyzes these impacts to show how exercise intensity, food, and metabolic health are interconnected. These findings help build evidence-based obesity prevention and treatment strategies for this demographic. Healthcare providers, legislators, and university stakeholders use this study to tackle college student obesity. The results suggest that campus wellness initiatives should focus on resistance exercise and diet to combat obesity. This research promotes exercise science and health behavior change theory for cross-cultural lifestyle interventions.
