Abstract

The aim of this study was to compare nerve conduction velocity (NCV) of lower limb in 3 groups (each group 8 subjects): soccer players (SOC), mid-endurance runners (MR), endurance runners (ER) and a control group (C) with the age range of 21-26. To evaluate electroneurography parameters and conduction velocity of each subject, separate peripheral nerve test with the electroneurography system (ENG) was performed. For data analysis, analysis of variance was used to compare mean nerve conduction velocity in dominant and non-dominant limbs of all groups and Tukey post hoc test was used in case of a difference among the groups. The results for both DL and NDL reported significant differences between MR and ER (P=0) (P=0) and between SOC and ER (P=0) (P=0). Also, there were significant differences between MR and C (P=0.002) (P=0.002) and between SOC and C (P=0) (P=0.013). In terms of the differences of DL and NDL, a significant difference was observed only in SOC (P=0.04). Based on the present study, it can be stated that probably nerve conduction of lower limb of athletes has developed mostly in higher intensity sports and it may be related to their similar energy systems. Also, dominant leg and a concentration on this leg is higher in training patterns of changing environment than mere endurance fields with constant environmental stimuli
