| 中文摘要: |
| 利用脑电超慢涨落技术（SET）对射击、射箭运动员安静状态下的脑电超慢涨落图信号系统的特征进行了研究。研究发现：（1）与普通人相比，射击、射箭运动员的全脑多巴胺的平均激活水平低于普通人，两者之间存在非常显著性差异。具体到各脑区，这种差异主要存在于右侧的额区、运动区及顶区。在这些脑区中，普通人的值均高于运动员。（2）优秀的射击、射箭运动员与一般的射击、射箭运动员相比，他们的全脑各神经递质的平均激活水平无显著性差异。而对各脑区各递质的激活水平的对比分析发现，INH在大脑的左侧额区、5-HT在左侧后颞区、Ach在左侧顶区、DA在右侧枕区及左侧后颞叶均存在显著性差异，NE在左侧顶区、EXE在右侧顶区均存在显著性差异。（3）对步枪、飞碟、手枪、移动靶及射箭五个项目运动员的全脑各神经递质平均激活水平的对比分析发现，各项目间均无显著性差异。而对各脑区各递质的对比分析发现，INH、5-HT、EXE、NE的激活水平在右侧顶区、左、右颞区、右枕区，不同项目间存在显著性差异。 |
| 英文摘要: |
| The technology of ultra-slow EEG fluctuations (SET) was applied to study the characteristics of ultra-slow EEG fluctuations map signal system of shooters and archers in tranquil state. The study reveals the following: 1. Comparing to ordinary people, the average activation level of whole-brain dopamine of shooters and archers is low. There is a significant difference between the two. The difference exists mainly in the right frontal part, motor area and parietal region of the brain. In those brain areas, the values of the ordinary people are higher than those of the athletes. 2. There is no distinct difference between the average activation levels of the whole brain neurotransmitters of the elite shooters and archers and those of the ordinary shooters and archers. A comparative analysis between the neurotransmitters of the different brain areas of the elite and ordinary shooters and archers shows that significant difference can be found in the following: INH in left frontal part, 5-HT in left posterior temporal area, Ach in left parietal region, DA in right occipital area and left posterior temporal lobe, NE in left parietal region and EXE in right parietal region. 3. A comparative analysis of the average activation level of the whole-brain neurotransmitters of the archers and the shooters of rifle, clay pigeon, pistol and moving target shows that there is no distinct difference between the athletes of different sports. While a comparative analysis between the neurotransmitters of the different brain areas reveals significant difference of the activation level of INH, 5-HT, EXE and NE in right parietal region, left and right temporal area, right occipital area as well as the different sports. |
