Figure 1. Typical trunk muscles activation profiles during a cutting maneuver for a representative participant at 60°. Raw EMG signals (mV) for external oblique (EOB), rectus abdominis (RAB) and erector spinae (ESP) left and right muscles are depicted from 0.2s prior to contact until 0.6s after initial contact. The first shaded area represents the pre-activity prior to the initial contact, the second shaded area depicts the weight acceptance phase and the vertical dashed line marks the end of the contact phase during the cutting maneuver.
