摘　　要：观察模拟4000m高住低练后力竭运动对大鼠肾EPO表达及RBC、Hb和HCT的影响,为科学的低氧训练提供实验依据.研究结果表明:(1)与常氧组相比,无论是高住组、常氧运动组或者高住低练组EPO值均升高,其中高住8 h组与常氧组相比EPO有显著性差异(P<0.05);(2)与常氧组相比,高住8 h组和高住12 h组RBC、Hb、HCT值上升,但无显著性差异(P>0.05),而常氧运动组和高住8 h运动组RBC、Hb、HCT值显著下降(P<0.05);高住8 h运动组与高住8h组比较,RBC、Hb、HCT值显著下降(P<0.05).适宜的低氧刺激可以提高机体的有氧能力,其中以低氧8小时的4周4000米海拔高度低氧刺激效果显著,考虑与EPO、RBC、Hb、HCT的升高有关;低氧后运动,血液RBC、Hb、HCT值显著下降,说明低氧刺激、运动强度过大,而使机体有氧能力下降.To study the effect of exhausted exercise aftesimulated 4000m HiLo training r on the Effect of Express of EPO and RBC, Hb, HCT in Rats of Renal. The result showed that ： 1 ） As compared with the group C, the EPO dyeing slice in groups ghHi increased significantly （P 〈 0.05）. 2） As compared with the group C, the result of RBC, Hb, HCT in groups T and 8hHiLo decreased significantly （P 〈 0.05）. There was statistical significance between group 8hHiLo and group 8hHi （ P 〈 0.05）. Conclusion I ） The hypoxia could increase the level of EPO, RBC, Hb and HCT, the proper hypoxia could increase the capability of exercise 2 ） Middling intention endurance training after exhausted exercise, the result of RBC, Hb, HCT changed probably one of the reasons leads to decrease antifatigue capability.
