摘要
探讨大学生体育课中补液对血液流变学的影响。10名男性大学生实验前一周作为安静状态(ST)对照,测试3堂课,隔周进行,分别为不补液课(NS)、补凉开水课(SW)和补运动饮料课(SS)。在体育课中使用遥测心率仪监测和询问自我运动感觉状况。课后即刻取血,采用普利生Precil N6B血液流变仪测定全血黏度;普利生Precil PLS-F200B黏度计测定血浆黏度;采用毛细管法测定红细胞压积和纤维蛋白原。结果发现ST和NS比较差异均无显著性(P>0.05);而ST和NS与SW和SS的血浆黏度、全血还原黏度、集聚指数、刚性指数、变形指数和电泳指数比较差异显著(P<0.05)。提示:体育课中补液改善了微循环的灌流情况,红细胞(RBC)的变形性提高,减少RBC破碎,有利于组织的氧和营养物质的供应,及代谢产物的排出,增强人体的运动和抗疲劳的能力,尤其是补运动饮料。
The author probed into the effect of fluid supplementation for college students taking a physical education class on hemorheology. One week before the experiment, 10 male college students were tested as the control in a calm condition. The students were tested for 3 classes （once in a fortnight）, which were respectively a fluid not supplemented class, a boiled water supplemented class and a sports drink supplemented class. During the physical education classes, the students were monitored by a remotely controlled heart rate monitor and asked about how they felt after exercising. Immediately after the classes, the students were blood sampled. Precil N6B blood rheometer was used to measure whole blood viscosity, Precil PLS-F200B viscometer was used to measure blood plasma viscosity, and the capillary tube method was employed to measure haematocrit and fibrinogen. The authors revealed that there is a significant difference （P 〈 0.05） in blood plasma viscosity, whole blood restoration viscosity, aggregation index, rigidity index, deformability index and electrophoresis index between the students tested before the experiment and taking a fluid not supplemented class and the students taking a boiled water supplemented class and a sports drink supplemented class, while there is no significant difference （P 〉 0.05） in the said measurements between the students tested before the experiment and the students taking a fluid not supplemented class. Hints： Fluid supplementation （especially sports drink supplementation） in the physical education classes improved the condition of flush flow in microcirculation, enhanced the deformability of red blood cells, and reduced the crash of red blood cells, thus being conducive to supplying the organs with oxygen and nutrition, to the discharge of metabolites, and to enhancing the sports capability and fatigue resisting capability of the human body.
