牛磺酸复合饮料抗疲劳的实验研究

通过动物试验研究牛磺酸复合饮料的抗疲劳作用。将雄性SD大鼠按体重随机分为4组，即空白对照组、阳性对照组、低剂量和高剂量牛磺酸复合饮料组。在给予受试物30d后测定各组大鼠爬杆时间和负重游泳的持续时间。试验前及试验第35天，大鼠在水温25℃±1℃的水中游泳90min，测定乳酸脱氢酶（LDH）、血乳酸（LAC）、血尿素氮（BUN）和肝糖原等生化指标。结果显示牛磺酸复合饮料组大鼠爬杆、游泳时间明显长于对照组（P〈0．01）；服用牛磺酸复合饮料的大鼠LDH活力、肝糖原均比对照组显著增加（P〈0．01），运动后血乳酸水平及BUN明显降低（P〈0．01）。由此可得出牛磺酸复合饮料具有抗疲劳作用。

An Experimental Study on Anti-fatigue Effects of a Mixed Taurine Beverage

Objective： To study the anti-fatigue effects of a mixed taurine beverage. Methods： Male SD rats were randomly divided into 4 groups according to their body weights： a solvent control group, a positive control group, a low dosage mixed taurine beverage group and a high dosage mixed taurine beverage group. After 30 d, a climbing test and a loaded swimming test were conducted on these groups of rats. Before the tests and after 35 d, the rats swam for 90 min in 25±1℃ water, and the lactic acid dehydrogenase （LDH）, blood lactic acid （LAC）, blood urea nitrogen （BUN） and hepatic glycogen contents were measured. Results： The climbing and swimming time of the rats of mixed taurine beverage groups were significantly prolonged as compared with those of the control groups （P〈0.01）; rats of mixed taurine beverage groups were obviously superior to those of the control groups in LDH activity and hepatic glycogen storage （P〈0.01）, and could significantly accelerate lactic acid and blood urea nitrogen （BUN） clearance after swimming （P〈0.01）. Conclusion： The mixed taurine beverage has anti-fatigue effects.
