Effect of exercise on hematological parameters: A study on trained versus un-trained male subjects

Exercise is known to affect many physiological parameters in body likewise hematological indices,with the shifts in fluids. exercising could be beneficial if continued un interrupted with healthy life style but acute physical activities found to cause drastic changes in both trained & un-trained individuals. this study was carried out at advance educational institute & research center (aeirc).the efforts were carried out to evaluate & compare the immediate affects of exercise in healthy trained & un-trained males. the venous blood samples were drawn from both groups before & after 30 min of jogging on treadmill. the blood is then investigated for the changes in hb,hematocrit,total leukocyte count,erythrocyte,platelets & reticulocyte count. immediately after termination of exercise the hemoglobin,hematocrit erythrocyte and leukocyte levels increased significantly when compared with pre-exercised values in both group while there was no significant change observed in platelet and reticulocyte count. moreover,beside changes in pre-exercised values among the trained and untrained subjects,the rise in erythrocyte and total leukocyte count was significantly more in trained subjects when compared with untrained. it is concluded that exercise is physiological stress to body which is healthy. it induces certain changes that enhance the ability to cope with stress. moreover,regular aerobic exercise improves the body ability to use oxygen and defense mechanism.
