Isometric bodyweight squats are fundamental exercises in athletic training and rehabilitation. Previously, we measured muscle activity a normal squat posture (NSP) with the center of foot pressure (COP) intentionally shifted forward as far possible (forward-shifted posture: FSP), patterns varied significantly according to COP location. This study focused on stepwise loading strategy. Ten health...

Surface electromyogram (EMG) finds many applications in the non-invasive characterization of muscles. Extracting information on control motor units (MU) is difficult when using single channels, e.g., due to low selectivity and large phase cancellations MU action potentials (MUAPs). In this paper, we propose a new method face problem case differential channel. The signal approximated as sum conv...
