Non‐uniform excitation of the pectoralis major muscle during flat and inclined bench press exercises

Autor: Liliam Fernandes de Oliveira, Hélio V. Cabral, Taian M. Vieira, Leonardo Mendes Leal de Souza

Publikováno v: Scandinavian Journal of Medicine & Science in Sports. 32:381-390

Non-physiological sources may lead to equivocal interpretation on the degree of muscle excitation from electromyograms (EMGs) amplitude. This presumably explains the contradictory findings regarding the effect of the bench press inclination on the pe

Differences between vastus medialis and lateralis excitation onsets are dependent on the relative distance of surface electrodes placement from the innervation zone location

Publikováno v: Journal of Electromyography and Kinesiology. 67:102713

Conflictual results between the onset of vastus medialis (VM) and vastus lateralis (VL) excitation may arise from methodological aspects related to the detection of surface electromyograms. In this study we used an array of surface electrodes to asse

The shear elastic modulus is one of the most important parameters to characterize the mechanical behavior of soft tissues. In biomechanics, ultrasound elastography is the gold standard for measuring and mapping it locally in skeletal muscle in vivo.

Is the firing rate of motor units in different vastus medialis regions modulated similarly during isometric contractions?

Autor: Alessio Gallina, Leonardo Mendes Leal de Souza, Hélio V. Cabral, Roger G. T. Mello, Liliam Fernandes de Oliveira, Taian M. Vieira

Publikováno v: Muscle & Nerve. 57:279-286

Introduction: Previous evidence suggests the fibres of different motor units reside within distinct vastus medialis (VM) regions. Whether the activity of these motor units may be modulated differently remains unknown. Here we assess the discharge rat

Is the EMGs Amplitude Distribution Spatially Localized in the Pectoralis Major Muscle During the Inclined Bench Press?

Autor: Liliam Fernandes de Oliveira, Felipe D. Mancebo, Leonardo Mendes Leal de Souza, Hélio V. Cabral

Publikováno v: XXVI Brazilian Congress on Biomedical Engineering ISBN: 9789811325168

This study implements the novel high-density surface electromyography (EMG) to investigate the distribution of pectoralis major (PM) muscle activity during the inclined bench press exercise. Six healthy male individuals participated in this study. Su

Innervation zone locations distribute medially within the pectoralis major muscle during bench press exercise

Autor: Leonardo Mendes Leal de Souza, Hélio V. Cabral, Felipe D. Mancebo, Liliam Fernandes de Oliveira, Taian M. Vieira

Publikováno v: Journal of electromyography and kinesiology : official journal of the International Society of Electrophysiological Kinesiology. 46

Changes in innervation zone (IZ) position may affect the amplitude of surface electromyograms (EMGs). If not accounted for, these changes may lead to equivocal interpretation on the degree of muscle activity from EMG amplitude. In this study we ask h
