From: EMG amplitude of the biceps femoris during jumping compared to landing movements
Rectified and smoothed EMG curves indicate electrical activity of the biceps femoris during: eccentric phase (Squat Jump (SJ) vs. Counter Movement Jump (CMJ)) and concentric phase (Braking Phase (BP) vs. CMJ). The EMG was divided in relation to eccentric vs. concentric phase. The dashed horizontal lines (right) indicate the maximum (100%) EMG measured during maximal voluntary contractions (MVC) while the horizontal lines (left) indicate EMG activity in mV.
