| 摘 要： | 目的:探讨补充不同浓度虫源壳聚糖对大鼠运动能力和骨骼肌抗氧化酶系的影响。方法:对大负荷游泳训练大鼠补充剂量分别为各组平均体重的0.5 g.kg-1、1.0 g.kg-1和2.0 g.kg-1的虫源壳聚糖,在8周大负荷训练结束后测定力竭游泳时间和骨骼肌抗氧化酶系的活性。结果:8周大负荷训练后,虫源壳聚糖大负荷运动组力竭游泳时间均明显长于单纯大负荷运动组,补充2.0 g.kg-1虫源壳聚糖组游泳力竭时间比单纯大负荷运动组延长了25.56%。补充虫源壳聚糖能够显著提高抗氧化酶系活性,虫源壳聚糖0.5 g.kg-1补充组与单纯大负荷运动组相比,CAT和GST酶活性显著升高(P<0.05),但SOD活性无显著差异;虫源壳聚糖1.0 g.kg-1和2.0 g.kg-1补充组与单纯大负荷运动组相比:SOD酶活性显著提高(P<0.05),CAT和GST酶活性升高极为显著(P<0.01)。MDA含量在不同水平虫源壳聚糖补充组均显著低于单纯大负荷运动组(P<0.01)。结论:补充虫源壳聚糖有助于提高训练大鼠的运动能力及骨骼肌抗氧化酶系活性。

| Abstract: | Objective:The effects of chitosan on antioxidant enzymes in skeletal muscle and exercise performance of rat were analyzed in this study.Methods:The chitosan were supplemented to rats that were given swimming training at three dose levels 0.5g.kg-1,1.0g.kg-1 and 2.0g.kg-1.The activities of antioxidant enzymes in skeletal muscle and exhaustive swimming time were measured after eight weeks training.Results:The exhaustive swimming time was longer for chitosan supplemented rat groups and it was 25.56% longer for... |
