目的：探讨高频重复经颅磁刺激（rTMS）的兴奋作用及其脑电活动,为使用rTMS提高运动员的唤醒水平提供理论基础。方法：采用2×2×2混合设计,在运动员左侧背外侧前额叶（DLPFC）施加20 Hz,90%RMT,3 000次rTMS（持续5 s,间隔55 s）,分别测试刺激前、后的自评兴奋度和脑电（EEG）。结果r：TMS刺激后男、女被试的自评兴奋性提高,额部α波、β波和央部β波的活动增强,顶部θ波和枕部δ波、θ波的活动减弱。结论：高频rTMS能够提高兴奋性r,TMS刺激后脑电活动的变化在一定程度上可以解释其神经生物学效应。

Objective： Investigate the excitation effects and electroencephalographic activity of high-frequency repetitive transcranial magnetic stimulation,for providing a theoretical foundation by using rTMS to improve athlete＇s arousal level.Method： Using 2×2×2 mixed design,given 20Hz,90%RMT,3000 pulses of rTMS（5s on and 55s off） on left DLPFC in athletes,subjective excitation feeling and EEG were measured respectively before and after.Results： Excitatory self-assessment raise,the activity of frontal alpha,beta and central beta were increase,the activity of parietal theta,occipital delta and theta were decrease after rTMS.Conclusion： High-frequency rTMS can improve excitation,the change of EEG after rTMS might partly be explained by the neurobiological effect of high-frequency rTMS.
