Relationship among Anthropometric Indices & Motor Nerve Conduction Velocity of Radial & Ulnar Nerves in Aerobic Trained Athletes

The purpose of this study was to investigate the relationship among anthropometric indices (upper extremity lengths and circumferences) and motor nerve conduction velocity (MNCV) of radial & ulnar nerve (bilateral side) in aerobic trained athletes (long distance runners & cyclists). A total of 50 male long distance runners & cyclists with an average age, height and weight of 23±2 years, 172.8±5.8 cm and 70.05±4.2 Kg respectively, volunteered to participate in this study. Each subject‘s MNCV was measured with the help of computerized equipment called ―NEUROPERFECT‖ (Medicaid Systems, India) and the data was analyzed using Mean ±SD and Pearson correlation. Results shows that MNCV of right radial and left radial was negatively and significantly related with right upper arm length (r=0.-40 p < 0.01) and left upper arm length (r=0.-37 p < 0.05). But a positive and significant relationship of MNCV of right ulnar and left ulnar was found between right upper arm circumference (r=0.33 p < 0.05) and left upper arm circumference (r=0.36 p < 0.05). Thus, it is concluded that the positive relationship of MNCV of radial and ulnar nerve in aerobic trained athletes may be the result of their long term training adaptations which may be further related to their pattern of movement requirement.
