摘要
目的通过实验观察补充茶多酚提取物对SD大鼠运动疲劳的作用。方法将50只雄性SD大鼠随机分为5组:安静组和模型组不给药,每天蒸馏水灌胃;高、中、低剂量组分别给予300,150,50 mg/kg的茶多酚提取物。30 d后,检测大鼠跑台力竭时间、运动后血乳酸水平、乳酸脱氢酶活力和血清尿素氮水平。结果茶多酚提取物可增加大鼠力竭时间,提高运动后大鼠血乳酸脱氢酶活力,同时降低大鼠运动后血乳酸及尿素氮水平,尤以300 mg/kg剂量的效果最明显。结论实验结果说明茶多酚提取物对运动大鼠有明显的抗疲劳作用。
Aim To experimentally observe the effect of the tea polyphenol extract on SD rats in terms of the sports fatigue. Methods 50 male SD rats were randomly divided into 5 groups： quiet group and model group daily tap water lavage; high, medium, low dose groups were given 300,150, 50 mg/kg tea polyphenol extract. After 30 days, the rats＇ treadmill exhaustive time, blood lactic acid after exercise level, lactic acid dehydrogenase activity and serum urea nitrogen level were detected. Results Tea polyphenol extracts can increase rats＇ exhaustive time, improve the blood lactate dehydrogenase activity, while reducing the rats after-exercise blood lactic acid and blood urea nitrogen levels, especially in the 300 mg/kg dose group, the effect is the most obvious. Conclusion The ex- periment results show that tea polyphenol extract has obvious anti-fatigue effect.
