      摘要:目的:通过脑电地形图观察太极拳运动前后脑电信号的变化特点,为进一步了解太极拳的神经机理提供依据。方法:采集运动前安静状态、运动后即刻、运动后安静状态的脑电信号,计算并比较各波段的功率值。结果:与太极拳运动前安静状态比较,运动后即刻慢波(δ波、θ波、α1)波功率值60%以上脑区表现为下降,而较快波(α2波、β1波、β2波)功率值70%脑区上升;有6个脑区的脑电总功率值增加。太极拳运动后,被试者安静状态下慢波(δ波、θ波、α1波)70%以上脑区功率值呈上升趋势;快波(α2波、β1波、β2波)70%以上脑区功率值下降;5个脑区的总脑电功率值有所减少。结论:进行太极拳运动时能够使快波(β波)功率值升高,慢波(θ波、δ波)功率值降低,且β波功率值的升高主要集中在大脑右侧区域,提高了两侧大脑的协同化;太极拳运动后安静状态,50%的脑区功率值较运动前的安静状态有所下降,提示可将太极拳作为运动员的放松手段;运动后即刻和运动后安静状态下额区的脑电功率值都有所增加,提高了植物神经系统对内脏活动的调节功能。
英文摘要:
      Abstract: Objective: The purpose of this study was to observe the change of EEG before and after Taichi by brain electrical activity mapping (BEAM), for providing references to understand neural mechanism of Taichi. Methods: EEG signals were collected before Taichi (rest state), immediately after Taichi, and rest state after Taichi, their power of different waves was calculated. Results: Compared with rest state, the power of the slow waves(δ, θ, α1)in more than 60% of brain areas decreased while the fast waves(α2, β1, β2)in more than 70% of brain areas increased in immediately after Taichi exercise, and the total power in six brain areas increased. In recovery state after Taichi, the power of the slow waves(δ, θ, α1)in more than 70% of brain areas increased while the fast waves(α2, β1, β2)in more than 70% of brain area decreased, the total power in five brain areas decreased. Conclusions: Taichi can increase the power of fast wave (β), decrease the power of slow waves (δ, θ), and the increase of β wave focused on right cerebral area, which can improve the coordination of both sides of cerebrum. Compared with rest state before Taichi, the power in 70% of brain areas increased in rest state after Taichi, which indicates that Taichi can be used as a relaxation method for athletes. The power in immediately after Taichi and in rest state after Taichi increased, which improved the regulation function of autonomic nervous system?on visceral activities.
