【摘要】：为研究苹果中原花青素对小鼠运动能力和抗氧化能力的影响,选取5周龄健康雄性小鼠45只,随机分为3组,进行3周适应性游泳训练。小鼠运动结束后,通过轻度麻醉条件下采集血液和肌组织,检测血清中乳酸(LD)和丙二醛(MDA)含量,以及测定超氧化物歧化酶(SOD)和过氧化氢酶(CAT)的活力。结果表明,各组小鼠的初始体重对比无显著差异(P0.05);运动对照组和试验组小鼠的游泳至力竭的时间明显长于安静对照组;与运动对照组相比,试验组小鼠的游泳至力竭的时间也呈现明显的延长趋势(P0.05)。游泳运动以后,运动对照组和试验组小鼠血清和肌组织中LD和MDA含量明显低于安静对照组;与运动对照组相比,试验组小鼠的血清LD和MDA含量也呈现明显下降趋势(P0.05)。另外,运动对照组和试验组小鼠SOD和CAT活性明显高于安静对照组,且与运动对照组相比,试验组SOD和CAT活性显著升高(P0.05)。说明苹果原花青素能提高小鼠运动能力和抗氧化能力,且与有氧运动相结合能够产生协同效应,具有较好的应用前景。
[Abstract]:In order to study the effect of procyanidins in apple on exercise ability and antioxidant ability of mice, 45 healthy male mice aged 5 weeks were randomly divided into 3 groups for 3 weeks of adaptive swimming training. Blood and muscle tissues were collected under mild anesthesia to detect the contents of lactate and malondialdehyde (MDAs) in serum, and the activities of superoxide dismutase (SOD) and catalase (CAT). There was no significant difference in the initial body weight of each group (P 0.05); the swimming time between exercise control group and test group was longer than that in quiet control group; compared with the exercise control group, the swimming time of the exercise control group was longer than that of the quiet control group. After swimming, LD and MDA contents in serum and muscle tissue of mice in exercise control group and test group were significantly lower than those in quiet control group, and compared with that in exercise control group. In addition, the activities of SOD and CAT in the exercise control group and the experimental group were significantly higher than those in the quiet control group, and compared with the exercise control group. The activities of SOD and CAT in the experimental group increased significantly (P 0.05), which indicated that the apple procyanidins could improve the exercise ability and antioxidant ability of mice, and the combination with aerobic exercise could produce synergistic effect, so it had a good application prospect.
