摘要
本研究应用可在非屏蔽状态下使用的便携脑电测试仪，对参加十运会游泳比赛的9名国内优秀游泳运动员赛前脑电进行测试分析，结果表明：运动员赛前的情绪状态与比赛结果紧密相关，脑电图可作为探求人体情绪状态的无创客观指标；运动员赛前脑电的α波优势节律在表象时较安静时有显著变化（P〈0．05），α波幅大小变化不明显，α能量百分比受抑程度仅为（19．84±8．57）％，而8活动在枕区变化明显（P〈0．05）；运动员赛前左右脑区脑波均衡性良好（P〉0．05），在颞区的β活动出现平衡被打破的迹象；赛前安静时脑电α波波幅适中（45μV左右），能量百分比在70％～80％之间，β波波幅在4～12μV之间，能量百分比在5％～10％之间。
By analyzing the EEG feature of 9 swimming athletes who attended the 10th National Games of China, it showed that Alpha advanced rhythm manifestations change evidently（ P 〈 0.05 ） between in the competition imagining in prior to competition and in the tranquil state; Alpha amplitude has no obvious changes, the percentage of Alpha energy was restrained in （ 19.84 ± 8.57 ） %, Beta activity on occipital area has obvious change（P 〈 0.05 ） ; the brain wave was coherence in both hemisphere（ P 〉0.05）, the evidence appears that means the Beta activity working in the temporal region is losing the balance ; the alpha power spectrum was moderate about 45μV,the energy percentage between 70% -80% ,the beta power spectrum was in 4-12/μV,the energy percentage between 5%-10% .
