Research on Effect of Aerobic Exercise and Nutrition Intervention on Food-borne Obesity

Abstract

With the development of social economy and the improvement of people's living standards, the incidence of obesity is increasing year by year. The main purpose of this study is to study the effect to food-borne obese rats combined aerobic exercise with soybean peptide and L-carnitine. The objects of this experiment are the SD obese rats which are successfully modeling, with 6-week training on treadmill and lavaging 10% of nutrient solution everyday (600 mg/ (kg．day) L-carnitine and 15 mg/ (kg．day) soybean peptide). But for the obese rats in the control group, they will be lavaged with 2 mL of distilled water. During this experiment, we observed the body weight, body length of the obese rats and calculate Lee’s index, detect the index of body weight, body length and the concentration of apolipoprotein. After the experiment, the exercise intervention group, the nutrition intervention group and exercise plus nutrition intervention group, Lee’s indexes of them are obviously lower than obese control group. The differences between two are all significant (p＜0.05), but there is no difference between three experimental groups (p＞0.05); Nutrition intervention, exercise intervention group and sport plus nutrition intervention all significantly decreased the levels of apoB (p＜0.05); the difference of effect on apoA between exercise intervention and nutritional interventions are not significant (p＞0.05), but sport plus nutrition intervention effect on apoA of obese rats has significant difference (p＜0.05). Through the analysis of these results, the experiment shows that feeding high fat and sugar fodder can successful establish obese rats model. Exercise and nutrition intervention can improve lipid metabolism, significantly decreasing apoB concentrations of obese rats, increasing apoA concentrations.
