以负重游泳的方法制备疲劳模型,观察小鼠力竭性游泳时间和游泳后的血糖、尿素氮及肝糖原水平。结果表明:高能营养液组、葡萄糖氨基酸组、葡萄糖组动物力竭性游泳时间比游泳对照组分别延长142.42%、83.23%和37.37%,高能营养液组和葡萄糖氨基酸组动物力竭性游泳时间与游泳对照组比较,差异极显著(P<0.01);游泳对照组与正常对照组比较,血糖、肝糖原含量均降低,尿素氮水平升高,差异均极显著(P<0.01);与游泳对照组相比,高能营养液组、葡萄糖氨基酸组、葡萄糖组的血糖和肝糖原水平均有所升高,尿素氮水平上升幅度减小。其中,高能营养液中高剂量组的血糖、血尿素氮、肝糖原与游泳对照组比较,差异极显著(P<0.01)。表明该宠物用高能营养液能有效维持游泳动物血糖、肝糖原水平,抑制蛋白质分解,增强体能,具有一定的抗疲劳作用。
The fatigue model was prepared by the method of weight-bearing swimming. The exhaustive swimming time and blood glucose, urea nitrogen and glycogen level were observed after swimming. The results showed that the exhaustive swimming time of high energy nutrient solution group, glucose amino acid group and glucose group animals were 142.42%, 83.23% and 37.37% longer than that of swimming control group respectively. Exhausted swimming time of high energy nutrient solution group and glucose amino acid group was (P <0.01). Compared with the normal control group, the levels of blood glucose and glycogen in the swimming control group decreased and the level of urea nitrogen increased significantly (P <0.01). Compared with the swimming group Compared with the control group, the levels of blood glucose and glycogen in the high-energy nutrient solution group, the glucose amino acid group, and the glucose group increased, while the increase in urea nitrogen level decreased. Among them, the blood glucose, blood urea nitrogen and glycogen in high-energy nutrient solution medium-high dose group were significantly different from the swimming control group (P <0.01). It shows that the pet with high-energy nutrient solution can effectively maintain the blood glucose, glycogen level of swimming animals, inhibit the protein decomposition, enhance physical fitness, and have a certain anti-fatigue effect.
