Abstract

The aim of the study was to investigate how zinc deficiency and supplementation effect some hematologic parameters of rats performing swimming exercise. Forty adult male Spraque-Dawley rats were divided into 4 groups, zinc deficient swimming group (Group 1, n=10), zinc supplemented swimming group (Group 2, n=10), swimming control group (Group 3, n=10), and control group (Group 4, n=10). Blood samples were taken by decapitation and analyzed for the determination of erythrocyte, hemoglobin level, hematocrit, leukocyte, lymphocyte, platelet count and plasma zinc level at the end of the 4 week experiment. Erythrocyte count of group 1 was the lowest whereas erythrocyte count in group 3 was significantly lower than that in group 2 and 4 (p<0.05). Hemoglobin level of group 1 was significantly lower than that of groups 2 and 4 (p<0.05). Hematocrit was significantly lower in both group 1 and group 3 than both groups 2 and 4 (p<0.05). Lymphocyte count in group 2 was significantly higher than in all other groups (p<0.05). Platelet counts in group 2 was significantly lower than in all other groups (p<0.05).  Our findings suggest that zinc deficiency effects the hematologic parameters mentioned negatively whereas zinc supplementation has a positive influence.
