中文摘要:

      目的 研究天然酵素运动饮料对小鼠的抗疲劳作用。方法 将健康雄性小鼠随机分为4组, 低、中、高剂量组和对照组, 灌胃剂量分别为10、20、60和0 mL/(kg?bw), 即对照组按同体积纯净水灌胃, 喂养30 d, 末次给药30 min后, 测定负重游泳时间、尿素氮、血乳酸、肌乳酸和肝糖原含量。结果 与对照组相比, 实验组小鼠的负重游泳时间和肝糖原含量明显增加(P<0.05), 血清尿素氮、血乳酸和肌乳酸含量明显降低(P<0.05), 且存在着一定的浓度依赖性。结论 此天然酵素运动饮料对小鼠增强运动耐力和消除疲劳具有一定的作用。

英文摘要:

      Objective To investigate the anti-sport fatigue effect of natural enzymes sport drink on mice. Methods Healthy male mice were randomly divided into 4 groups: the low, medium and high dose groups and the control group. The intragastric doses were 10, 20, 60, and 0 mL/(kg?bw), respectively, which the control group was filled with the same volume of pure water. The mice were fed for 30 d, and 30 min after the last administration, the weight-bearing swimming time, serum urea nitrogen, blood lactic acid, sarcolactic acid and glycogen contents were measured. Results Compared with the control group, the times of weight-bearing swimming test and the contents of glycogen were significantly increased in the experimental groups (P<0.05), and the contents of serum urea nitrogen, blood lactic acid and sarcolactic acid were significantly decreased (P<0.05), showing a certain concentration dependence. Conclusion The natural enzymes sport drink has a certain effect on strengthening sports endurance and eliminating fatigue in mice.
