Abstract
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.
摘要
当人类受试者接球时，拮抗肌的反射性和预期性共同激活被证明会发生。视觉信息的存在会强烈调节肌电图（EMG）反应的幅度和时间进程。有人认为，这些反应是预先在中枢设定好的，以便在球撞击后稳定肢体。
