The following plots show the EMGs of eight different muscles druing a platform jump. The eight muscle parts are quadriceps, hamstring, tibialis anterior, gastrocnemius, trapezius, sternocleidomastoid, abdominus, and paraspinal. In the plots, the yellow lines are the EMG traces and the blue lines indicate the muscle onset. The red vertical line represents the actuall impact for the platform jump, whereas the greeen lines indicate the impact for the no platform jump. The EMG Onsets are determined by a MATLAB script which can be found by clicking this link: EMG Onset.
