| 摘 要： | 目的:以游泳大鼠为研究对象,通过检测其补充茶多酚过程中身体成分和脂肪代谢的变化,探讨茶多酚补充对游泳大鼠脂肪代谢的影响及机理.方法:将雄性Wistar大鼠40只随机分为4组(安慰剂对照组、运动对照组、补充茶多酚对照组和补充茶多酚运动组).采用沉淀法测定大鼠血清LDL-C和HDL-C水平;酶法测定血清TC和TG;比色法测定血清LPS、LPL和HL.结果:4周茶多酚补充可明显减缓游泳大鼠体重和体脂增长速度,明显降低大鼠血清TC水平及游泳大鼠血清LDL-C水平.同时,茶多酚补充可明显提高游泳大鼠血清LPL含量,并一定程度地降低其血清HL水平.结论:茶多酚补充可在一定程度上减慢游泳大鼠体重和体脂的增长速度,加快其能量代谢速度;可能会通过影响游泳大鼠脂肪代谢相关调控酶水平,使其血脂水平下降,进而影响其脂肪代谢过程. |

| Abstract: | Purpose : Taking male swimming rat s as the research subject s to study the effect s and mechanism of tea polyphenols supplement on fat metabolism in order to reveal the changes with regard to the swimming ratps body composition and fat metabolism. Methods : 40 male Wistar rat s were randomly divided into 4 groups :cont rol group ,exercise group ,group with tea polyphenols supplement and exercise group with tea polyphenols supplement . The serum LDL - C and HDL - C were determined by sedimentation method ,the TC and TG by Enzymatic method and serum L PS ,L PL and HL by colorimet ry. Result s : The result showed that the tea polyphenols supplement with four weeks could remarkably weaken weight and body fat of swimming rat ,decrease the level of serum TC and LDL - C of rat s. Meanwhile ,tea polyphenols supplement could increase serum L PL level and decrease serum HL level. Conclusion : Tea polyphenols supplement could accelerate the speed of body energy metabolism and decrease the weight and body fat during exercise. Through adjusting the levels of enemies of lipoid metabolism ,the body blood lipid levels decrease in order to further influence the process of fat metabolism. |
