摘要 目的:观察健康受试者在运动性肌肉疲劳过程中大脑中枢电信号与外周肌肉表面肌电电信号通讯之间的变化,为丰富运动性肌肉疲劳的中枢机制理论提供参考依据。方法:以15名健康受试者为研究对象,通过上肢间断性握力收缩诱发其指屈肌疲劳,观察疲劳过程中运动皮质区的β波段(15~30 Hz)脑电、指深屈肌肌电以及脑电与肌电相干性的变化。结果:在疲劳过程中位于FC1、FCz、FC2、C1电极位置的β波段标准化能量谱显著性下降(P〈0.05);指深屈肌s EMG的15~30 Hz标准化能量谱随着疲劳发生显著下降(P〈0.05)。FC1、FCz、FC2、C1以及Cz电极位置的β波段脑电-肌电相干性随着疲劳的加重显著性下降(P〈0.05)。结论:在小强度运动诱发上肢肌肉疲劳的实验中,β波(15~30 Hz)频率带的EEG和EMG功率谱随着疲劳的加重而显著性降低,同时β波(15~30 Hz)频率带对应的EEG-EMG相干性显著性下降。 Objective: This study observed the communication between central electroencephalography( EEG) signals and peripheral muscle electromyography( s EMG) signals of healthy subjects,in order to provide reference for the central mechanisms on exercise-induced muscle fatigue. Methods: This study examined β band waveform EEG signal( 15- 30 Hz) in motor areas,relevant band s EMG signals of flexor digitorum profound muslces,and EEGs EMG coherence from 15 healthy subjects during the muscle fatigue induced by intermittent digitorum flexor contractions. Results: Normalized β band spectrum significantly decreased( P〈0. 05) in the FC1,FCz,FC2,and C1 electrode sites during the muscle fatigue; the s EMG signal of band 15- 30 Hz of flexor digitorum profound muscles in the normalized spectrum significantly decreased( P〈0. 05); EEG-s EMG coherence in the β band in the FC1、FCz、FC2、C1,and Cz electrode sites significantly declined( P〈0. 05) with development of muscle fatigue. Conclusion: The power spectrums of β band EEG and s EMG signals( 15- 30 Hz) decrease with development of forearm muscles fatigue induced by low intensity exercise,and the EEG-s EMG coherence( 15- 30 Hz)also significantly declines.
