    摘要: 　　本研究利用腦波(EEG)及事件相關腦電位(ERP)分析技術作為工具，探討易筋經運動對於認知的可能影響。方法：本研究共召募28名健康成年人受試者，依功齡長短，區分為長期運動組（LT，共11名）、短期運動之初學組（ST，共7名）及控制組（CTL，共10名）。LT組和ST組由授課教練帶操實作易筋經運動；CTL組則進行與易筋經運動量相仿的30分鐘散步運動。運動後皆有充足的休息（約 10分鐘），以確保實驗結果不會受到血壓升高，心率，或體溫等生理因素的干擾。三組受試者在運動前、運動後，都必須接受EEG/ERP的測量。本研究中以10-20為標準，選取Fz為腦波記錄點，以坐姿閉眼進行6分鐘的EEG/ERP實驗，取0-1分鐘的EEG參數α、β及θ波的平均功率當作比較的基準值。ERP檢測使用怪球典範（oddball paradigm）的不同頻率聲音刺激，誘發明顯的P300振幅和潛伏期。統計使用單因子變異數分析（One way ANOVA），p< .05代表有統計上的意義。結果： P300潛伏期在前、後測之變化率Δ%方面，LT組和ST組均顯著大於CTL組（p<.05），而LT組與ST組之間則無顯著差異。結論：本研究表明，雖然作用機制仍然不明，易筋經運動可能發揮提高認知功能的作用。
    　　In this study we examined the effects of Yi Jin Jing exercise on cognitive functions with an auditory event-related potential (ERP) paradigm. Method: Twenty-eight adults were recruited and divided into three groups: The experienced practitioners group (LT, n=11), the beginning practitioners group (ST, n=7), and the control group (CTL, n=10). Amplitudes and latencies of P300 on Fz evoked by a standard auditory oddball paradigm before and after 30 minutes Yi Jin Jing exercise were collected and compared with control subjects, who walked briskly for 30 minutes. Adequate rest (roughly 10 minutes) was provided to make sure the experiment results were not confounded by elevated blood pressure, heart rate, or body temperature. Statistical significances were determined using analysis of one-way ANOVA with p<.05. Results: The Δ% of the latency of P300 on LT and ST groups were significantly larger than the CTL. On the other hand, the difference between LT and ST groups were not significant. Conclusions: The present study indicates that Yi Jin Jing exercise might play a role on improving cognitive activities, although the mechanisms are still unknown. Further studies are warranted to evaluate the effects of this popular exercise in Chinese communities.
