Anticipatory and reflex coactivation of antagonist muscles in catching.
Reflex and anticipatory coactivation of antagonist muscles is demonstrated to occur when human subjects catch a ball. Amplitude and time course of the electromyographic (EMG) responses are strongly modulated by the presence of visual information. It is argued that these responses are centrally preset to stabilize the limb after ball impact.
