目的：观察适应性训练、补充海洋肽以及大豆蛋白后骨骼肌bFGF及desmin含量的变化,研究运动训练、补充海洋肽以及大豆蛋白对运动性肌肉损伤和修复的影响。方法：以雄性SD大鼠72只,随机分为：安静组、运动组、运动＋海洋肽组、运动＋大豆蛋白组。进行6周适应性离心运动训练即-5°下坡间歇跑,跑速从20.0 m/min递增至35.0 m/min,每次10~20 min,每周训练5 d,之后给予定量离心负荷,分别取运动后即刻、24 h和48 h不同时间处死、取股中间肌、测试。结果：6周适应性训练可以增强desmin的适应能力。补充海洋肽组股中间肌desmin蛋白丢失较少。补充大豆蛋白组运动后即刻bFGF蛋白表达量显著性低于安静组,运动后48 h组bFGF蛋白表达量显著性高于运动后即刻组。结论：补充海洋肽能够更好的减少离心运动后骨架蛋白的丢失,促进运动后骨骼肌损伤的修复。

Objective： To investigate effect of training,the marine bioactive peptide and soybean protein supplementation on content changes of desmin and bFGF after eccentric exercise in rats.Methods： Male SD rats were randomly divided into non-exercise control group and three training groups： group of supplying marine bioactive peptide,group of supplying soybean protein and group of supplying water.In 6-wk training with five days/wk,the speed raised from 20.0m/min to 35.0m/min,and the grade was always-5°.In the seventh week,the tissues were collected separately at 0h,24h and 48h after eccentric exercise.Results： 1.The desmin content decreased at 0h and began to rise at 48h after eccentric exercise.2.Supplying soybean protein could reduce the loss of desmin.3.bFGF protein content increased earlier than desmin.Conclusion： Supplying soybean protein can repair desmin after eccentric exercise to some extent.Supplying marine bioactive peptide can reduce the loss of desmin better,but not by regulating bFGF.
