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.

The complex interactions among the structural features of axon, its myelin sheath and its length, determine the nature of nerve impulse conduction. In addition, fibers of different diameters and degree of myelination determine the nerve conduction velocity (NCV). It is therefore, hypothesized that for the same nerve, the NCV may differ in animals, due to the differences in the leg architecture and its movement during locomotion. The purpose of this study was to compare right and left limb's sciatic NCV in three different classes of animals to identify differences, if any, and to relate these differences with different types of gait locomotry pattern observed in them. The Compound Action Potential (CAP) was recorded from both the right and left isolated sciatic nerves from adult Frog, Uromastix and Rabbit of both sexes. through Power Lab and its accessories. These CAP records were then used for the calculation of NCV, Significant difference was observed in sciatic NCV being greater in order of Frog>Rabbit>Uromastix. These differences were found well correlated with differences in their gait and locomotion. However, there was no significant difference among right and left sciatic nerve's NCV for both Uromastix and Rabbit, while it was significantly different for Frog. The differences in NCV among Frog, Uromastix and Rabbit's sciatic nerves reflect differences in these animals for their sciatic nerve diameter, leg architecture, gait and locomotion, as per their habitat.
