摘要
目的研究以玛咖、管花肉苁蓉为主要原料的保健食品对缓解体力疲劳的作用。方法将SPF级ICR雄性小鼠按体重随机分组,每天摄入成品推荐摄入量的5、10、30倍作为低、中、高剂量,即0.25、0.50、1.50 g/(kg?bw),设蒸馏水为阴性对照组,灌胃给予受试物连续30 d后,测定小鼠尾根部负重的游泳时间,于不同实验组分别检测小鼠运动后血清尿素含量、肝糖原、运动前后的血乳酸含量。结果连续灌胃玛咖片30 d后,高剂量组1.50 g/(kg?bw)能明显延长小鼠尾部负重游泳时间,显著降低小鼠游泳后血清尿素含量,以及小鼠游泳后血乳酸含量,并且与阴性对照组相比具有显著性差异(P<0.05)。结论玛咖片作为保健食品具有缓解体力疲劳功能。
Objective To study the effect of Maca tablet with material Maca and Cistanche tubulosa (Schenk) Wight as main raw material on alleviating physical fatigue. Methods SPF grade ICR male mice were randomly separated into 3 doses (0.25, 0.50, 1.50g/(kg?bw) respectively, and the negative group were given the equivalent pure water, by gavage for 30 days, and the swimming time with heavy load in the tail was measured. Then the serum urea content, the content of hepatic glycogen and different time point blood lactic acid area after exercise were measured in different groups. Results After continuous gavage of maca tablets for 30 days, the high-dose group in 1.50 g/(kg?bw) could significantly prolong the swimming time with heavy load in the tail of mice, the serum urea content and blood lactic acid content of mice after swimming were significantly reduced, and the difference was significant compared with the negative control group (P<0.05). Conclusion Maca tablet as a health food has the function of relieving physical fatigue.
