We examined the effect of expertise on cortical activation during sports anticipation using functional MRI. In experiment 1, recreational players predicted badminton stroke direction and the pattern of active clusters was consistent with a proposed perception-of-action network. This pattern was not replicated in a stimulus-matched, action-unrelated control task. In experiment 2, players of three different skill levels anticipated stroke direction from clips occluded either 160 ms before or 80 ms after racquet-shuttle contact. Early-occluded sequences produced more activation than late-occluded sequences overall, in most cortical regions of interest, but experts showed an additional enhancement in medial, dorsolateral and ventrolateral frontal cortex. Anticipation in open-skill sports engages cortical areas integral to observing and understanding others' actions; such activity is enhanced in experts.
我们使用功能磁共振成像研究了专业技能对运动预期过程中皮层激活的影响。在实验1中，业余运动员预测羽毛球击球方向，活跃簇的模式与提出的动作感知网络一致。在刺激匹配、与动作无关的控制任务中未重现这种模式。在实验2中，三个不同技能水平的运动员从球拍与球接触前160毫秒或后80毫秒被遮挡的片段中预测击球方向。总体而言，在大多数感兴趣的皮层区域，早期遮挡序列比晚期遮挡序列产生更多激活，但专家在内侧、背外侧和腹外侧额叶皮层表现出额外增强。开放技能运动中的预期涉及观察和理解他人动作所必需的皮层区域；专家的这种活动增强。
