Impact of High-Intensity Interval Training on Body Mass Index in College Students

Introduction: Due to academic pressure, many college students feel unmotivated to exercise, leading to serious obesity problems. One of the effective resources for weight loss is high-intensity interval training, but there is no extensive research on the effect on this specific group. Objective: To explore the impact of high-intensity interval training on body fat index (BFI) in college students, analyzing the scientific basis and safety of this exercise training through heart rate indicators. Methods: Two experimental groups, MICT (moderate-intensity continuous training) and HIIT (high-intensity interval training), were compared. The HIIT group used stationary bicycles, according to the high-intensity interval training method. MICT is a moderate-intensity continuous training method, so the load was half that of the HIIT group. Results: The IGC of women after training was 22.81±2.87, the IGC was significantly reduced, and there was a very significant difference; the IGC of men after training was 22.74±2.12, the IGC was significantly reduced, and they very significant difference. This shows that the exercises have a good effect on weight loss. Conclusion: HIIT training is more effective, both in time and strength of adherence. It has a good effect on improving cardiopulmonary function, and optimizing IGC are strongly impacted. Level of evidence II; Therapeutic studies - investigation of treatment outcomes.
