以前的研究已经调查了长期运动训练对运动过程的大脑活动的影响，但结果并不一致。为了阐明获得运动专业知识如何在运动任务执行过程中诱发皮层重组，本研究对26项功能性磁共振成像（fMRI）研究进行了定量荟萃分析，这些研究调查了具有长期运动训练经验的人（如运动员、音乐家和舞蹈家）和对照参与者的运动任务表现。对运动专家和新手的大脑激活的荟萃分析显示，双侧额叶和顶叶区域的效果相似。运动专家与新手的meta分析结果显示，在运动执行和预测任务中，专家对左顶叶下小叶（ba40）的影响强于新手。在运动观察任务中，专家对左侧额下回（ba9）和左侧中央前回（ba6）的影响明显强于新手。相反，与运动专家相比，新手在右侧运动区和基底节区有更强的影响。这些结果表明，运动专家在涉及动作计划和动作理解的脑区有效果增加，并表明强化运动训练可能会细化与任务表现相关的运动表征。
Previous research has investigated the influence of long-term motor training on the brain activity of motor processes, but the findings are inconsistent. To clarify how acquiring motor expertise induces cortical reorganization during motor task performance, the current study conducted a quantitative meta-analysis on 26 functional magnetic resonance imaging (fMRI) studies that investigate motor task performance in people with long-term motor training experience (e.g., athletes, musicians, and dancers) and control participants. Meta-analysis of the brain activation in motor experts and novices showed similar effects in the bilateral frontal and parietal regions. The meta-analysis on the contrast between motor experts and novices indicated that experts showed stronger effects in the left inferior parietal lobule (BA 40) than did novices in motor execution and prediction tasks. In motor observation tasks, experts showed stronger effects in the left inferior frontal gyrus (BA 9) and left precentral gyrus (BA 6) than novices. On the contrary, novices had stronger effects in the right motor areas and basal ganglia as compared with motor experts. These results indicate that motor experts have effect increases in brain areas involved in action planning and action comprehension, and suggest that intensive motor training might elaborate the motor representation related to the task performance.
