Abstract:
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,parietal-occipital 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 junction areas decreased slightly;however,the before-and-after comparison was not significant. The brain complexity of the treatment group in the frontal pole,frontotemporal,frontal,frontal-central junction,central,central-parietal junction,posterior-temporal,parietal,parietal-occipital junction,and occipital areas increased. The posterior-temporal,parietal,parietal-occipital junction,and occipital areas had more significant increases than the other areas. However,the before-and-after comparison was not significant. In both groups,brain complexity decreased in the frontotemporal junction,middle temporal,and temporoparietal junction areas and increased in the parietal,parieto-occipital junction,and occipital areas. The comparison of complexity between the treatment and control groups in P3 and PO3 leads after training was significant. P3 and PO3 are situated in the parietal region and parieto-occipital junction areas,respectively,indicating that antebellum breathing also affects brain function in these regions. The correlation between the respiratory curve and EEG components was enhanced after training. Conclusion Abdominal breathing training can significantly increase the complexity of the corresponding brain regions (posterior temporal,parietal,and parieto-occipital junction regions),and a significant correlation was observed between the two.
