气功腹式呼吸调节脏腑气血功能的效应研究

Analysis of Qigong Abdominal Breathing′s Effect on Zang-Fu Qi and Blood Function

目的通过分析心率变异性(heart rate variability,HRV)以及井穴的血流灌注量(blood perfusion,BP),探究腹式呼吸对人体脏腑气血功能的调节效应。方法以健康成年人为受试对象,按照1∶1的比例分成试验组和对照组。试验组采取三圆式站桩姿势进行腹式呼吸练习,对照组采用平行、仅站桩干预对照方法。在8周干预训练前后,分别采集心率变异性及井穴的血流灌注量进行比较分析。结果HRV方面,自然态下试验组的LF、SDNN、RMSSD、pNN50在干预前后差异有统计学意义(P<0.05),对照组干预前后差异无统计学意义(P>0.05);练功态下试验组的LF、LF/HF、SDNN、RMSSD、pNN50与对照组相比差异有统计学意义(P<0.05)。井穴血流灌注量方面,试验组干预后井穴的血流灌注量,与干预前相比明显上升,且差异有统计学意义(P<0.05)。对照组干预后数值虽略较干预前升高,但差异并无统计学意义(P>0.05)。结论腹式呼吸对于人体的脏腑气血功能具有良性的调节作用,具体表现为通过慢、细、匀、长的腹式呼吸操作,提高膈肌的运动范围,不仅可以提升迷走神经张力,而且加强肢体末端井穴血流灌注量,对人体内脏腑气血运行具有正向的促进调节趋势。

Objective To analyze the function of Zang-Fu Qi and blood during abdominal breathing exercise through the analysis of heart rate variability(HRV)and blood perfusion(BP)of well points.Methods Healthy adults were recruited and divided into experimental group and control group according to the proportion of 1:1.The experimental group practiced the abdominal breathing by using three-circle posture standing,while the control group only practiced the three-circle posture standing.Before and after 8 weeks of intervention training,HRV and BP of well points were collected for comparative analysis.Results In terms of HRV,there were significant differences in LF,SDNN,RMSSD and pNN50 in the experimental group before and after intervention under natural state(P<0.05),but there was no significant difference in the control group before and after intervention(P>0.05).The levels of LF,LF/HF,SDNN,RMSSD and pNN50 in the experimental group were significantly different from those in the control group under practicing state(P<0.05).The BP of well points in the experimental group after intervention was significantly higher than that before intervention,and there was significant difference(P<0.05).The BP of the control group after intervention was slightly higher than that before intervention,but there was no significant difference(P>0.05).Conclusion Abdominal breathing has a benign regulatory effect on the function of Zang-Fu Qi and blood.The specific manifestation is to improve the range of motion of the diaphragm through slow,thin,uniform and length abdominal breathing operation.It can not only enhance the tension of vagus nerve,but also promote the BP of well points at the end of limbs,which has a positive trend of promoting and regulating the movement of Zang-Fu Qi and blood in human body.
