Impacts of Aerobic Exercise on the Obesity of Adolescents and Their Lipid Metabolism

Abstract

Introduction: The obesity rate of Chinese adolescents has reached an alarming level, where about 11% of Chinese children are overweight, making them more prone to diseases such as hypertension, abnormal physiological metabolism, and high joint wear of the lower limbs. This public health problem can be alleviated with healthy habits, including aerobic exercise. Objective: Study the effect of aerobic exercise on obesity and lipid metabolism in adolescents. Methods: In this randomized controlled trial, 40 young volunteers were equally allocated into experimental and control groups. The control group received no intervention, while the experimental group was trained according to a professionally designed aerobic exercise protocol for 28 days. Training data were recorded before, during, and after the exercises. The information was processed, compared, and analyzed. Results: The control group failed to reduce body fat effectively; an aerobic exercise in the experimental group showed better effects in reducing body weight, body fat, waist-to-hip ratio, and weight loss; compared to the control group. Immediately after the intervention, the HDL level of the experimental group showed an upward trend, while the TC, TG, and LDL indices showed a downward trend. Conclusion: Aerobic exercise can effectively increase muscle mass and basal calorie and fat intake, reducing youth obesity. Level of evidence II; Therapeutic studies - investigating treatment outcomes.
