Background: The aim of this study was to describe motor nerve conduction velocity of selected nerves of both the upper and lower extremities in sportsmen. Thirty high-level sprinters (100mts & 200 mts) and thirty high level distance runners (3000mts) were volunteered to participate in the study. Method: Motor Nerve Conduction Velocities (MNCV) of Ulnar and Common Paroneal Nerve (CPN) were recorded with the help of computerized equipment -Neuroperfect (Medicaid Systems, India) with standard techniques of supramaximal percutaneus stimulation with constant current and surface electrodes. The anthropometric measurements taken were Body Height (cms), Age (yrs) and Body weight (kgs). The neurophysiological parameters taken were MNCV of Ulnar Nerve (upper extremity) and Common Peroneal Nerve (lower extremity) of both sides (i.e.dominant and non-dominant) of the body. The room temperature was maintained at 37 degree Celsius. Results: Significant differences in motor nerve conduction velocities were found between dominant and non-dominant limbs in each group. Ulnar nerve conduction velocity measured from above elbow to below elbow was significantly higher in the sprinters than long distance runners. The CPN nerve conduction velocity is significantly higher in distance runners as compared to sprinters. Conclusion: The motor nerve conduction velocity of ulnar nerve was found to be higher in sprinters as compared to the distance runners, and the MNCV for CPN is higher in distance runners as compared to sprinters. The MNCVof ulnar and CPN were higher in dominant limbs (i.e. arms & legs) of both sides of the body as compared to non dominant limbs.
