高原训练对机体血液指标及红细胞2,3-二磷酸甘油酸影响的研究

The Influence of Plateau Training to the Blood Index and 2,3-DPG of RBC

机体在高原训练环境下发生一系列生理生化的变化。红细胞、血红蛋白、红细胞压积均有不同程度升高,其中血红蛋白变化有一个或两个峰值,提示下高原后一段时间运动能力高峰期存在;高原训练后EPO水平大幅度升高;红细胞2,3-DPG有明显升高趋势,缺O2时,2,3-DPG使氧离曲线右移是否有利,还值得怀疑,有待进一步探讨。高原训练可以有效提高红细胞变形能力,但这种变形能力会随着下高原时间的延续而逐渐消失。

Human body will have a series of physiology occurrence on the blood index, 2, 3-DPG in red cell and Blood lactic acid under the plateau training in this environment. RBC, which shans RHb and Hct will have a different degree to go up, among them RHb＇s change will have one or two higher points that the ability of exercise will go into highest point one period after the plateau training;After plateau training the EPO level will go up greatly; 2, 3-DPG in RBC obviously will go up. Whether 2, 3-DPG making the curve move right when lacking of 02 is good for us is still doubtable, and it needs our further research. Plateau training can improve the ability of RBC to change its shape effectively. But this ability will disappear with the time going after departing from the plateau conditions.
