摘　　要：运用脑电地形图仪(NDC-2000)对15名国家优秀男子跆拳道运动员的脑机能特征进行研究。结果显示,α波指数被抑制程度(大脑唤醒水平)存在水平上的显著差异(国际健将为34.62±1.66%;健将为27.66±3.32%;一级为26.87±3.12%);我国男子跆拳道队高水平运动员的大脑功率谱比值在3左右;β波和θ波指数整体相对偏低;同时,对跆拳道运动员进行间歇性节律闪光刺激试验发现,国际健将组比其他两组更灵敏、更协调、更稳定且恢复疲劳时间更短。结论:脑电α波被抑制的程度、大脑功率谱能量比值以及α波、β频和θ波等指标均可作为男子跆拳道运动员训练监控指标,今后应加强不同水平的运动员α波指数被抑制程度和功率谱能量比值的匹配诊断,逐步提高运动员α波指数抑制的临界水平,提高运动员的注意能力和恢复能力。By EEG testing（ NDC - 2000）,15 elite taekwondo athletes were analyzed,the results showed that the significant level of α wave index was found in different elite athletes （international grade：34. 62 ± 1. 66% ;national grade：27. 66 ± 3. 32% ;one grade：26. 87 ± 3. 12% ）;the ratio of brain power spectrum is about three;β wave and θ wave were lower;meanwhile,by using intermittent rhythm flash stimulation,it is suggested that international grade is more sensitive,coordinated and stable than other grades. Conclusion：α wave,β wave and wave can be see as the indicators for training monitor for taekwondo,this indicators should be strengthen in the future,and the critical level of α wave should be improved in future training in order to promote the attention ability and recovery capacity.
