The authors randomly divided 12 male Wistar rats into a control group and a kinetic hypochrosis group. After 5 weeks of training, the authors took samples, measured hermoreheological indexes of the rats by using a hermoreheological instrument, observed the morphological indexes of erythrocytes by using blood smears, and revealed the following findings: the whole blood viscosity and reduced viscosity of the rats in the kinetic hypochrosis group are all significantly lower than the same of the rats in the con-trol group (P<0.01), while the erythrocyte rigidity index of the rats in the kinetic hypochrosis group is significantly higher than the same of the rats in the control group; there is no significant difference in blood plasma between the rats in the two groups; blood smears indicate that there are more erythrocyte fragments in the rats in the kinetic hy-pochrosis group. The findings indicate that the decrease of the number of erythrocytes and the deterioration of the deformation ability of erythrocytes are important causes for triggering kinetic hypochrosis.
