摘要
分析优秀气步枪运动员不同状态下大脑顶枕区脑电变化特征,以期为备战2020年东京奥运会气步枪项目运动员机能状态监测与训练效果评估提供数据支持以及理论参考依据。采用脑电信号采集设备对24名优秀气步枪运动员在不同状态下大脑的左右顶区、枕区4个位置(P3、P4、O1、O2)脑电信号进行数据采集与复杂度分析。研究结论:(1)优秀步枪射击运动员脑电波α、β频段参数的变化与以往其他项目运动员不同状态下脑电变化规律一致,因而这2个频段的脑电参数可作为对不同训练状态进行评估的手段之一;(2)不同运动等级组别气步枪运动员实射状态下的大脑唤醒水平具有一定差异,表明其长期的专业射击训练有可能对运动员大脑唤醒水平产生一定的影响;(3)在实弹射击状态下,高环值与低环值成绩之间的差异可能与运动员顶区中枢神经放电的有序程度有一定关系,视觉信息的参与则不是影响运动员成绩高低的主要因素。
The characteristics of EEG changes in the parieto occipital region of the brain of elite air rifle athletes in different states were analyzed, providing data support and theoretical reference for the monitoring of air rifle athletes’ functional state and the evaluation of training effect in preparation for the 2020 Tokyo Olympic Games.In this paper, the EEG signal acquisition equipment was used to collect and analyze the EEG signals of the left and right parietal and occipital regions(P3, P4, O1, O2) of 24 elite air rifle athletes in different states.Conclusion:(1)The changes of the parameters of α and β band of the brain wave of the elite rifle shooter are consistent with those of other athletes in different states.Therefore, the parameters of the two bands can be used as one of the means to evaluate the different training states.(2)There are some differences in the level of alertness of air rifle athletes in different sports levels under the actual shooting state, which indicates that their long-term professional shooting training may have a certain impact on the level of alertness of athletes.(3)In the state of actual shooting, the difference between the performance of high and low score of athletes may be related to the order of the central nerve discharge in the top area of athletes, while the participation of visual information is not the main factor affecting the performance of athletes.
