摘 要:目的探究气功腹式呼吸训练对人体脑功能的调节效应。方法招募在校大学生72名,按1∶1比例随意分为对照组和试验组。对照组与试验组分别干预,两组的站桩功操作相同,仅试验组加入腹式呼吸干预训练。干预过程包括集中培训2周和辅导训练6周。在培训前(基线期)和训练后分别进行心电图和脑电图(EEG)检测。应用样本熵算法和经验模态分解对EEG信号进行分析,计算样本熵复杂指数,分析脑电变化与呼吸曲线的关联性。结果训练后,试验组不同脑区复杂度均高于对照组,颞顶交界区、后颞区、顶区、顶枕交界区、枕区脑复杂度差异较大,其中,试验组后颞区脑复杂度明显高于对照组(P<0.05)。与训练前比较,对照组在额极区、前颞区、额区、额颞交界区、额中央交界区、中颞区、中央区、颞顶交界区的大脑复杂度下降,在中央顶交界区、后颞区、顶区、顶枕交界区、枕区上升,但差异无统计学意义;试验组在额颞交界区、中颞区、颞顶交界区的大脑复杂度下降,在额极区、前颞区、额区、额中央交界区、中央区、中央顶交界区、后颞区、顶区、顶枕交界区、枕区的大脑复杂度升高,但差异无统计学意义。两组大脑复杂度均在额颞交界区、中颞区、颞顶交界区下降,在顶区、顶枕交界区、枕区升高。训练后试验组与对照组在P3和PO3导联复杂度比较,差异有统计学意义,P3和PO3分别位于顶区和顶枕交界区,提示顶区和顶枕交界区也存在顺腹式呼吸对脑功能的影响。训练后呼吸曲线与脑电成分相关性增强。结论腹式呼吸训练可明显增加大脑相应脑区(后颞区、顶区、顶枕交界区)的复杂度,且二者存在明显的关联性。Objective To investigate the effects of qigong abdominal breathing training on human brain function.Methods Seventy-two university students were recruited and randomly divided into the control and treatment groups in a 1∶1 ratio.Both the control and treatment groups underwent the same standing pile work operation.However,only the treatment group received additional abdominal breathing training.The intervention process comprised two phases:2 weeks of intensive training and 6 weeks of counseling training.Electrocardiogram and electroencephalogram(EEG)tests were performed before(baseline period)and after training respectively.Sample entropy algorithm and empirical mode decomposition were used to analyze the EEG signals.The sample entropy complexity index and the correlation between EEG changes and respiratory curves were calculated to explore the brain function regulation effect.Results The complexity of different brain regions in the treatment group was higher than that of the control group after training.A large difference was observed when comparing the brain complexity in the temporoparietal junction,posterior temporal,parietal,parietal-occipital junction,and occipital regions.The brain complexity in the posterior temporal region of the treatment group was significantly higher than that of the control group after the intervention,with a significant difference(P<0.05).In the control group,the brain complexity in the frontal pole,anterior temporal,frontal reion,frontal-temporal junction,frontal-central junction,middle temporal,central,and temporal-parietal junction regions decreased to different degrees.However,the comparison between before and after was not significant.Furthermore,brain complexity in the central-parietal junction,posterior temporal,parietal,parietaloccipital junction,and occipital regions increased to different degrees in the control group;however,the difference was not significant.The brain complexity of the treatment group in the frontotemporal junction,middle temporal,and temporoparietal jun
