Abstract: The purpose of this study was to investigate whether the VMO muscle had greater EMG activity than the VL muscle in maximal effort isometric contraction of hip adduction with knee extension at sitting position and decubitus lateralis. The electrical activity was measured on 15 healthy subjects (24.4 ± 4.1 years old) without prior hip and knee pathologies, using a 8 channels Nicolet Electromyograph and Beckman mini surface electrodes. The EMG recordings were analysed according to Basmajian's classification, giving percentage degrees of intensity. The results showed that the EMG activity of the VMO muscle was not significantly greater (test t of Student at 5% of significance) in both exercises of maximal isometric hip adduction when compared with the VL muscle. These findings, within the experimental conditions used, suggest that the maximal isometric hip adduction exercises with knee extension did not produce a selective strengthening of the VMO muscle.
