This study evaluates the consequences of a session of intensive short-duration exercise and Zn supplementation on different hematological variables. Forty male Wistar rats were divided into four groups (n = 10): the first nonsupplemented, maintained at rest (R); the second nonsupplemented, undergoing exercise (E); the third supplemented with Zn, kept at rest (ZnR); and the fourth supplemented with Zn, undergoing exercise (ZnE). Zinc supplements (200 ppm) were given in drinking water. The exercise consisted of a single session of swimming until exhaustion. At rest, RBC, Hb, and Hto fell (p < 0.05), whereas red cell indices, MCV, and MCH rose (p < 0.05) in +ZnR compared with R; MCHC remained unchanged (ZnR vs R). After exercise, RBC, Hb, and Hto increased significantly in E and in ZnE compared with R and ZnR, respectively. In addition, RBC and Hb were lower (p < 0.01) in ZnE compared with E; however, MCV and MCH were higher (p < 0.05) in the group ZnE vs E. With respect to white blood cells--leukocytes (WBC), lymphocytes (LYMPH), and neutrophils (NEUT)--no significant differences were observed between groups at rest (ZnR vs R). WBC and LYMPH increased significantly in E with respect to the rest situation (E vs R), but this did not happen in supplemented animals (ZnE vs ZnR). Level of pH decreased after exercise both in E and in ZnE, but the fall was lower in the latter. We believe that a single session of swimming until exhaustion leads to an increase in RBC, Hb, and Hto without causing changes in MCV, MCH, and MCHC.(ABSTRACT TRUNCATED AT 250 WORDS) |
