| Abstract |
The purpose of this study is to observe the effects of pine needles powder intake and athletic training on the energy metabolic substrates. To achieve this purpose, 42 Sprague-Dawley male rats were selected to feed pine needles powder and swimming exercise for 5 weeks. There was no significant difference in the weight increase rate while intaking pine needles powder and exercising at the same time. Compared to the swimming exercise group, high cholesterol diet group and high cholesterol diet+swimming exercise group, the pine needles powder intaking group and pine needles powder intake+swimming exercise group suppressed AMPK expression, significantly. Thus, for the result of GLUT-2 and GLUT-4 which are the glucose transporter of liver and skeletal muscle, the pine needles powder intaking group and pine needles powder intake+swimming exercise group showed significantly higher expression. For the glycogen content of liver and muscle, the pine needles powder intaking group and pine needles powder intake+swimming exercise group increased significantly. Therefore, the findings of this study would be used as the basal data of exercise nutrient supplements as the pine needles powder intake gives positive effect on the energy storage capacity. |
