【摘要】 目的研究抗氧化剂槲皮素对大鼠运动能力的影响。方法以跑台训练建立动物模型,测定了大鼠运动力竭时间和肌糖原含量、骨骼肌组织超氧化物歧化酶(SOD)、谷胱甘肽过氧化物酶(GSH-Px)、丙二醛(MDA)含量及血清肌酸激酶(CK)的活性。结果服用槲皮素后大鼠力竭时间明显延长;肌糖原含量升高;力竭即刻骨骼肌组织SOD,GSH-Px活性升高,MDA含量显著降低,血清酶CK活性的上升幅度显著降低。结论槲皮素能通过增加肌糖原含量,减轻骨骼肌自由基损伤来提高大鼠的运动能力,可作为一种运动保健品开发利用。更多还原

【Abstract】 Aim To study the effect of quercetin on exercise performance and protecting tissues from sports injury.Methods By setting up endurance training+axhaustive exercise model,some indices in rat are measured including muscle glycogen content,activity of SOD,GSH-Px in muscle and serum CK.Results Compared with control groups quercetin obviously prolongs exhausetive exercise time;increases musscle glycogen content;remarkably restains the decreased activity of SOD,GSH-Px and increased activity of MDA in muscle after exhaustive exercise.Conclusion Quercetin,one kind of effective anti-oxidative substance,can improve exercise performance in trained rat by increasing muscle glycogen and relieving sports injury of muscle tissue,hence,it will be explored as sports healthy food.更多还原
