| 摘 要： | 了解不同水平射击运动员的脑电α波特点，为射击运动员的科学选材和训练控制提供一定的参考依据。方法：采用高级运动训练状态监控仪采集、分析了19名国家射击队运动员和19名广东省射击运动员不同训练阶段的152个样本的脑电α波信号。结果：不同水平射击运动员的脑α波类型无显著性差异，但高水平运动员表现出了较高的协同趋势和稳定度；不同水平运动员的熵值及脑α波各类型主频熵值均无显著性差异，但奥运冠军与国家队、广东省队协同稳定度高的被试的熵值存在显著性差异。 国家队认知型和优化型运动员的脑电α波主频与熵值呈显著性负相关。结论：不同水平射击队员的脑电α类型仿向认知型，认识型可作为射击运动员选材的参考指标；高水平射击运动员的训练适应状态和竞技水平的稳定程度均优于低水平运动员；熵值可作为监控优秀射击运动员训练适应状态的参考指标。

| Abstract: | Objective To investigate the characteristics as to provide reference for scientific talent selection and the Advanced Training Control Monitoring to collect and shooters of Chinese National Shooting Team and 19 training stages. Results There is no significant difference between the EEG a wave types of the shooters of different levels, But the high-level shooter display higher cooperation trend and stability There is no distinct difference between the entropies and the dominant frequency entropies of. the different EEG α wave types of the different level shooters. But significant difference can be found between entropies, of the Olympic champions and those of the higher stability athletes of the national and Guangdong teams. There is negative correlation between the EEG α wave dominant frequencies and the entropies of the cognitive and optimal type athletes. Conclusion EEG α wave types of the different ,leVel shooters tend to be cognitive. So cognitive type can be regarded as the reference indicator for selecting shooters. The training conditioning and the stability of the competitive level of the top shooters are better than the shooters of low level. Entropy can be used as the reference indicator in monitoring the training conditioning of the elite shooters. |
