【摘要】：运动表象质量与运动技能水平有关,运动表象质量随着运动技能水平的提高而上升。器械使用可使人脑产生可塑性改变,使用者会将器械纳入身体图式。然而,两者影响运动表象的神经心理机制还不清楚。本研究采用功能性磁共振成像探析篮球运动员与新手在不同持球条件下表象投篮时脑功能活动的差异。结果表明运动员表象质量较好,镜像神经系统激活高于新手;持球条件下运动员表象质量显著高于不持球条件下,镜像神经系统激活程度显著低于不持球条件下。研究说明持器械可以显著提高运动员的表象质量,器械使用带来镜像神经系统的可塑性变化。
[Abstract]:The quality of motor imagery is related to the level of motor skills, and the quality of motor imagery increases with the improvement of motor skills. The use of devices can make the human brain plastic changes, the user will incorporate the device into the body schema. However, the neuropsychological mechanisms that affect motor appearances are unclear. In this study, functional magnetic resonance imaging (fMRI) was used to analyze the difference of brain function between basketball players and novice players under different ball holding conditions. The results showed that the image quality of athletes was better, the activation of mirror nervous system was higher than that of novice, and the image quality of athletes under ball holding was significantly higher than that of non-ball holding, and the activation degree of mirror nervous system was significantly lower than that of non-ball holding. The results show that instrumentation can significantly improve the image quality of athletes, and the plasticity of mirror nervous system is caused by the use of instruments.
