摘要
目的观察剧烈运动中脱水对血液黏度的影响。方法对上海海平面地区健康士兵作5 km越野运动,测试运动前、运动后即刻及运动后1 h血细胞比容、血浆比黏度、全血切变率为10 s和110 s的比黏度,计算全血还原比黏度。结果运动后即刻血细胞比容、全血比黏度、全血还原比黏度比运动前明显升高(P<0．01),运动后1 h血细胞比容与运动前无明显差别,全血比黏度、全血还原比黏度低于运动后即刻(P<0．05),但高于运动前(P<0．05)。运动前、后血浆比黏度无明显差别。结论脱水是海平面地区剧烈运动中血液黏度升高的主要因素之一,运动前、运动中和运动后补充电解质溶液以维持体液和电解质的相对稳定是防范运动意外的重要措施。
Objective To study the influence of dehydration on the blood viscosity increase induced by strenaous exercise. Methods Hhemorheological indexes （HCT, Tη0P η0b, and η0bre） before and after exercise were determined from 20 exercisers running for5 km in plain above sea level.Results The values of HCT, η0b and η0bre immediately after exercise were higher than those before exercise（ P 〈 0.01）. The values of η0b and η0bre an hour later after exercise were lower than those immediately after exercise（ P 〈 0.01 ）, but higher than those before exercise （ P 〈 0.05）. The values of HCT showed no significant defference pulations an hour later after exercise from those before exercise. The value of η0p had no significantl changes in populations after exercise. Conclusions Dehydration is an important factor of blood viscosity increase induced by vigorous exercise. Complementartion of fluid is a beneficial measure in this condition.
