【摘要】：在實彈射擊條件下,研究瞄準期間腦電信號(EEG)中alpha波頻段的功率特性,及其與射擊成績的關(guān)系。采用Holter-16D便攜式腦電信號放大器,采集參加全國司法警察大比武陜西代表隊選拔集訓的法警在射擊訓練中的EEG。通過功率譜分析和時頻分析,得到被試alpha主頻(IAF)、左右顳區(qū)alpha波段功率差值。結(jié)論是:(1)在靜息態(tài)時,射擊運動想象時所運用的alpha波類型劃分方法不能完全適用于實彈射擊前的靜息態(tài)中。(2)在實彈射擊瞄準期間,左右腦alpha波頻段功率偏差值與alpha波集中于左顳區(qū)的趨勢呈正相關(guān)。(3)在實彈射擊中,瞄準期間左右腦alpha波頻段功率偏差值與射擊成績呈正相關(guān)。
[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.
