中文摘要:

目的：探讨世居高原和世居平原体育生的血液流变学与有氧运动能力间的相关关系，以及两者血液流变性在性别差异上的异同。方法：分别以30名（男女各半）世居高原和世居平原体育生为研究对象，清晨空腹状态采静脉血进行血液流变学指标测试；餐后1 h，进行有氧运动能力测试。结果：世居高原体育生男性的高、低切全血粘度、还原粘度、相对粘度及红细胞变形指数（TK）值显著高于女性，血浆粘度（PV）显著低于女性；世居平原体育生男性低切全血粘度、还原粘度及相对粘度显著高于女性，高切还原粘度及TK值显著低于女性；世居高原男性体育生的有氧运动能力与PV和红细胞压积（HCT）呈显著负相关，与TK值呈显著正相关。结论：从血液流变学角度，世居高原女运动员的红细胞变形能力、红细胞运输和传递氧的能力高于男性，而世居平原体育生中呈现相反的情况；世居高原体育生血液流变与有氧运动能力的相关性较世居平原体育生密切。

英文摘要:

Objective: The study aims to analyze the correlation between blood rheology and aerobic performance between native plateau athletes and native plain athletes, and the difference of blood rheology in different gender athletes. Methods: Thirty native plateau and plain collegiate athletes (15 men and 15 women) were chosen as the subjects. Blood rheology parameters were tested early in the morning with venous blood collected at the time of empty stomach. While the aerobic performance was tested one hour after the meal. Results: The male native plateau athletes had distinct higher values of whole blood viscosity(WBV) in high and low shear rates, WBRV, relative viscosity and TK than the female native plateau athletes. While their PV is significantly lower than that of the female plateau athletes. The male native plain athletes had distinct higher value of WBV in low shear rate, WBRV and relative viscosity than the female plain athletes. While their WBV in high shear rate and TK are significantly lower than those of the female native plain athletes. The Aerobic performance of the male native plateau athletes significantly had a negative correlation with PV and HCT, and a positive correlation with TK. Conclusion: From the hemorheological point, the female native plateau athletes' capacity of RBC deformability and RBC's carrying and delivering oxygen are higher than those of the male athletes. Opposite phenomenon exists in native plain athletes. The correlation between the blood rheology and aerobic performance of the native plateau athletes is closer than that of the native plain athletes.
