Effects of Short-term Aerobic Exercise and Nutrition on Physical Fitness and Metabolism of Obesity Adolescents / 中国康复理论与实践

ABSTRACT

@# ObjectiveTo evaluate the effects of aerobic exercise, nutrition or both on physical fitness and metabolism in obesity adolescents. Methods94 overweight/obese adolescents (12～16 years old) underwent 10 weeks exercise alone, nutrition intervention alone, and exercise combined with nutrition, respectively. The physical and metabolism index were detected before and after intervention. ResultsThe body mass index (BMI), body fat, body fat% decreased in all the groups. Especially, exercise alone decreased total cholesterol (TC), increased fasting insulin (FINS), insulin resistance (HOMA-IR), and function of β-cells (HOMA-β). Nutrition alone decreased TC, low-density lipoprotein cholesterol (LDL-C). Exercise combined with nutrition decreased TC and LDL-C, increased FINS and HOMA-β. High-density lipoprotein cholesterol (HDL-C) tended to decrease in all the groups. ConclusionThe aerobic exercise and /or nutrition intervention can improve the lipid metabolism, Exercise can improve function of the β-cell of pancreas. But the effects of exercise and/or nutrition on HDL-C and insulin resistance are not satisfactory.
