摘　　要：目的:研究牛奶和鸡蛋对运动能力的影响,探讨牛奶和鸡蛋对运动疲劳恢复影响的可能机制.方法:将普通成体雄性ICR小白鼠(18只)随机均分对照组(CG)、额外补充牛奶组(MG),额外补充鸡蛋组(EG);采用10d递增负荷的游泳运动方式使小白鼠力竭.分析牛奶与鸡蛋对小白鼠力竭运动后血糖、血红蛋白(Hb)、血肌酐(CRE)含量影响及体重变化,记录力竭时间、观察行为状态.结果:与实验前比较,各组小鼠实验后血糖、血红蛋白(Hb)浓度下降,血肌酐(CRE)浓度上升;两实验组小鼠体重增加均显著高于CG组;两实验组与CG相比,运动时间显著延长.结论:小鼠运动疲劳后,机体出现各种疲劳指标的变化,额外补充牛奶和鸡蛋可以减少这些疲劳指标的改变.可能是通过增加糖储备来提高运动能力,保证机体在长时间运动时的能量来源;减缓运动过程中对蛋白质的过度利用;增加体内磷酸肌酸的贮备,提高磷酸肌酸的代谢能力等方面缓解运动疲劳的,尚待进一步研究.The aim of the study is to understand the effect of milk and eggs on exhaustion exercise mice. The ordinary adult ICR mice （18）were random divided into 3 groups.The control group is feed normal food（CG）,one experimental group named MG is feed additionally 1 ml milk and the other experimental group named EG is feed additionally 1 g milk.Through the extra supplement of milk and eggs,the swing-ing time,the weight,hemoglobin （Hb）,serum creatinine were observed.Results：The blood glucose, hemoglobin （Hb）concentration of the experiment group drop compared with the previous experiments and the serum creatinine （CRE）concentration rises.The body weight of the mice in two experimental groups was significantly increased higher than the CG group;the exercise time in the two experimental groups significantly prolonged compared with the CG.Conclusion：Milk and eggs supplementation can reduce in-dicators which changed by the exercise fatigue of mice.The reason may be to improve exercise capacity by increasing the sugar reserves to ensure the body during prolonged exercise energy sources and to slow down the use of protein during exercise excessive and increase the body＇s reserve of creatine phosphate to alleviate sports fatigue.
