通过EEG的测试,探讨青少年女子气手枪运动员不同环数击发前左、右颞区（T7和T8）、枕叶中线（Oz）、运动区（Cz）的α波功率和额叶中线（Fz）的θ波功率变化特征。研究发现：1）运动员在安静闭眼、睁眼状态下,左、右颞区（T7、T8）的α波功率值没有显著性差异;2）在击发前3s,运动员左颞区（T7）的α波功率值显著高于右颞区（T8）的值;3）在击发前3s,运动员枕叶中线（Oz）的α波脑电功率值呈上升趋势,其中,击发前倒数第3s的值显著低于倒数第2s的值;4）在击发前3s,运动员10环的额叶中线（Fz）θ波功率值显著高于8环的值。

This study focused on the characteristics of Pre-shot EEG during female adolescent air-pistol shooting. The log-transformed alpha wave power spectral estimates from best shots and worst shots was compared at sites T7 , T8 , Cz, Oz and the log-transformed theta wave power spectral estimates at sites Fz also was compared. The result reveals that 1 ） The log- transformed alpha wave power spectral estimates of shooters ＇ during the resting period with eye opened or closed was not significantly different at siteT7 and T8. 2 ） Over an 3-s period preceding the trigger pull, the log-transformed alpha wave power spectral estimates at sites T8 is significant lower than that of at sites T7 during shooting. 3 ） Over an 3 s period preceding the trigger pull, the log-transformed alpha wave power spectral estimates at sites OZ was grad- ually increased, the alpha power from 3 seconds preceding the trigger to the time of the trigger is significant lower than that of last 2 seconds. 4） the log transformed theta wave power spec tral estimates of the 10-score shots was higher than that of the 8-score shots.
