目的:探讨健身气功六字诀对事件相关电位P300的影响,为六字诀锻炼对认知功能影响的评价提供实验支持。方法:采用上海海神医疗电子仪器厂生产的NDI-200(海神号)神经电检诊仪记录并分析了18名女性受试者分别进行健身气功六字诀和瑜伽完全呼吸锻炼前及锻炼后即刻Pz点的视觉诱发事件相关电位及反应时。结果:与锻炼前相比,锻炼后即刻P300潜伏期显著性缩短(P<0.05),而波幅和反应时都无显著性差异。结论:健身气功六字诀对认知功能具有正向影响效应,表现为P300潜伏期显著缩短。
Objective: To investigate the effect of Qigong Liujian formula on event-related potential P300, and to provide experimental support for the evaluation of the effect of Qizhu tactic on cognitive function. Methods: The NDI-200 (Poseidon) neuro-electrical diagnostic apparatus produced by Shanghai Poseidon Medical Electronic Instrument Factory was used to record and analyze the data of 18 female subjects before and after exercise Pz point visual evoked event-related potential and response time. Results: Compared with that before training, the P300 latency was significantly shortened (P <0.05) immediately after exercise, but no significant difference was observed between amplitude and response time. Conclusion: Qigong Six-Point Formula has a positive effect on cognitive function, showing a significant shortening of P300 latency.
