The purpose of the present investigation was to examine the effect of concentric isokinetic leg extension training on peak torque (PT) and mechanomyographic (MMG) responses. Twenty-one males were assigned into a training (TRN, n = 12) or control (CTL, n = 9) group. The training group performed six sets of ten leg extensions three days per week for twelve weeks at a velocity of 90°.s-1. All subjects were tested every four weeks for PT and MMG responses at a velocity of 90°.s-1. The two-way mixed factorial ANOVA indicated a significant increase (p < 0.05) in PT over the twelve weeks for the TRN group but no significant change (p > 0.05) in PT for the CTL group. For the MMG there was no significant (p > 0.05) interaction, therefore, the TRN and CTL groups exhibited the same pattern of responses over the twelve-week training period. The reason for the increase in PT in the absence of a change in MMG may be due to hypertrophy and/or changes in other muscles involved in leg extension.
