【摘要】：在实弹射击条件下,研究瞄准期间脑电信号(EEG)中alpha波频段的功率特性,及其与射击成绩的关系。采用Holter-16D便携式脑电信号放大器,采集参加全国司法警察大比武陕西代表队选拔集训的法警在射击训练中的EEG。通过功率谱分析和时频分析,得到被试alpha主频(IAF)、左右颞区alpha波段功率差值。结论是:(1)在静息态时,射击运动想象时所运用的alpha波类型划分方法不能完全适用于实弹射击前的静息态中。(2)在实弹射击瞄准期间,左右脑alpha波频段功率偏差值与alpha波集中于左颞区的趋势呈正相关。(3)在实弹射击中,瞄准期间左右脑alpha波频段功率偏差值与射击成绩呈正相关。
[Abstract]:Under the condition of live firing, the power characteristics of alpha wave band in EEG during aiming are studied, and the relationship between the power characteristics and firing results is also studied.The Holter-16D portable EEG amplifier is used to collect the EEGG in shooting training of the judicial police officers selected by Shaanxi team in the national judicial police competition.By power spectrum analysis and time-frequency analysis, the power difference of alpha band in left and right temporal regions was obtained.The conclusion is that the alpha wave classification method used in shooting motion imagination can not be fully applied to the rest state before firing.There was a positive correlation between the power deviation of left and right brain alpha wave band and the tendency of alpha wave concentration in the left temporal region.
