WebDuring the ballistic movements, EMG activity was recorded by surface electrodes attached over the agonist (biceps) and antagonist (triceps) muscle of movement. EMG signals were amplified and full wave rectified. Data were analysed off-line by inspecting the single trials on a computer screen. WebAt the fastest movement speeds, triphasic EMG patterns (Ag 1 -Ant-Ag 2, Ag 1 being first activation of agonist muscle) were always present. This data indicated that the triphasic pattern of muscle activation was not switched on when a particular t mov was achieved.
