This present study explored the effects of a twelve-week body-weight-based high-intensity interval training (HIIT) program on body composition and physical fitness in obese university students. Methods: Sixty-one participants completed a total of 36 sessions of weight management classes over twelve weeks. Each intervention session included 40 seconds of 14 sets of high-intensity exercises at 85%-90% of Hrmax (such as burpees, mountain climbers, etc.), with 20 seconds of recovery in between. Body composition, Cooper 12-minute run , 50-meter sprint, and standing long jump were measured before and after the intervention. Results: Participants showed significant reductions in weight, BMI, and TBF% after the intervention, with statistical significance (p < 0.05). Besides, participants showed significant improvements in the Cooper 12-minute run and 50-meter sprint. However, there was no significant change in the standing long jump performance (p > 0.05), suggesting that the impact of HIIT on lower body power may be limited. Conclusion: High-intensity interval training (HIIT) shows positive effects on body composition and physical fitness in obese university students, demonstrating its potential application as a university physical education program.References
