Sponsor's own description
The goal of this randomized controlled trial is to test whether a dual-dimensional 9-grid matrix intervention improves body composition and exercise adherence compared to standard aerobic exercise in overweight/obese college students. The main questions it aims to answer are: Does the 9-grid model optimize fat distribution (measured by waist-hip ratio) and sustain body fat reduction better than traditional exercise? Does dynamic risk stratification in the 9-grid system enhance long-term exercise adherence? How does spatial migration of participants within the grid (quantified by centroid index G) reflect intervention efficacy? Researchers will compare the 9-grid management group (receiving dynamic positioning + 5-tier personalized strategies) to the control group (receiving standardized aerobic exercise) to see if the 9-grid model: Reduces waist-hip ratio more effectively Delays intervention plateau in body fat loss Increases exercise adherence at 8 weeks Participants will: Undergo body measurements (weight, body mass index (BMI), body fat percentage, waist/hip circumference) at baseline, 4 weeks, and 8 weeks Complete the Exercise Adherence Rating Scale (EARS) at 4 and 8 weeks If in 9-grid group: * Be classified into 1 of 9 grid zones every 2 weeks based on waist circumference risk + body fat status * Receive zone-specific interventions (nutrition/exercise/behavioral guidance) If in control group: * Perform progressive aerobic exercise (40-90% heart rate reserve (HR) 3×/week * Use heart rate monitors for intensity tracking
