目的：探讨两个不同海拔地区剧烈运动前后血液流变性的变化。方法：对４０名平原健康青年在海捷拔３８００和５３００米两地区进行５公里越野跑前后血液流变学１０项指标检测。结果：在海拔３８００和５３００米越野跑后较前血液粘度增加，ＴＫ（红细胞变形系数）及 ＩＲ（红细胞刚性指数）减弱，ＨＣＴ（红细胞压积）和ＰＦＣ（纤维蛋白原）及 ＶＡＩ（血细胞聚集）增加。越野前在海拔５３００米较３８００米的血液粘度增加，ＴＫ、ＩＲ无显著性差异，ＰＦＣ增加显著（Ｐ＜０．０５）。其余指标升高。剧烈运动后海拔５３００较３８００米，ＩＲ一项无统计学意义，９项指标增加。结论：高原血液流变学指标的变化与高尺低氧低气压、海拔高度及剧烈运动有关。
Objective: To investigate the changes of hemorheology before and after vigorous exercise in two different altitudes. Methods: 40 plain healthy youngsters were tested in 10 indexes of hemorrheology before and after 5 km of cross country running at 3800 and 5300 meters in Haitepu district. RESULTS: Compared with the increase in blood viscosity, TK (erythrocyte deformability) and IR (erythrocyte rigidity index), HCT (hematocrit) and PFC (fibrinogen) and VAI )increase. Off-road before the elevation of 5300 meters 3800 meters higher blood viscosity, TK, IR no significant difference, PFC increased significantly (P <0.05). The rest of the indicators increased. Strenuous exercise after the elevation of 5300 3800 meters, IR a non-significant, 9 indicators increased. CONCLUSION: The changes of hemorrheological indexes in plateau are related to hypobaric hypobaric altitude, altitude and strenuous exercise.
