摘　　要：利用脑电超慢涨落技术和《中国射击运动员恢复—应激问卷》对夏训不同训练负荷前后,上海移动靶运动员安静状态下脑电超慢信号系统(尤其是神经递质信息)和心理状态的变化特点进行了测试与分析。研究结果发现,在夏训不同训练阶段,移动靶运动员全脑神经递质的平均激活水平无显著性差异。而从各脑区各递质的变化来看,INH在左前颞的激活水平有显著性变化,夏训前的值均低于上量两周后及上强度一周后的值。ACh在左顶叶区有显著性变化,夏训前的值高于上强度训练后的值。INH在左前颞的激活水平有显著性变化,夏训前的值高于上量两周后的值。在夏训不同训练阶段,运动员的休息受干扰和睡眠质量两个分量表存在显著性差异。与夏训前相比,上强度训练一周后的休息受干扰分量表值高于夏训前的值。上量训练两周后的睡眠质量分量表值低于夏训前的值。Applying ultra-slow EEG fluctuation technology and the questionnaire on Chinese shooters＇ recovery and stress,the authors tested the variation characteristics of the ultra-slow EEG signal system,especially the neurotransmitter information and mental status of some Shanghai moving target shooters in tranquil state before and after the summer training with different training loads.The result shows that in the different phases of the summer training,there is no significant difference in average activation level of the whole brain neurotransmitter of the moving target shooters.Concerning the changes of the transmitters in different brain areas,obvious changes of activation level of INH in left anterior temporal are observed.The value before the training is lower than that two weeks after the load-increased training and one week after the intensive training.ACh changes are distinct in.the left parietal area.The value before the training is higher than that after the intensive training.There is significant changes of activation level of INH in left anterior temporal area.The value before the training is higher than that two weeks after the load-increased training.During the different phases of the summer training,there is obvious difference between the subscales of disturbed rest and sleep quality.The value of disturbed-rest subscale is higher than that before the summer training.The value of sleep quality subscale the two weeks after the load-increased training is lower than that before the training.
