Gender comparison in EMG amplitude during maximal voluntary contractions of the upper limb muscles

Gender comparison in EMG amplitude during maximal voluntary contractions of the upper limb muscles

In earlier studies of Electromyography (EMG), many researchers used surface Electromyography (sEMG) to investigate the relationship between the EMG signal and the muscle activation among males and females. The purpose of this study is to compare the EMG amplitude on upper limb muscles (Biceps and Fo...

The purpose of this study is to compare the EMG amplitude on upper limb muscles (Biceps and Forearm) during maximal voluntary contractions (MVC) of isometric exercise between males and females.

The 2 sample t-test about the value of RMS and MAV with force value was performed in Minitab to test the significance among these variables.
