College of physical Education, South China Normal University, Guangzhou 510631, China） Abstract: The author probed into the effect of fluid supplementation for college students taking a physical educa-tion 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 rheom-eter 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, aggrega-tion index, rigidity index, deformability index and electrophoresis index between the students tested before the ex-periment 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 be-tween 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.
