摘要
目的通过分析心率变异性(HRV)时域和频域指标,探寻站桩功对焦虑状态的调节效应。方法以在校大学生志愿者(焦虑自评量表≥50分)为受试对象,按里1?1配比随机分为试验组和对照组,试验组进行为期10周、每周不少于5次的三圆式站桩功练习干预,对照组不进行任何干预。在站桩功干预开始前与完成后,分别采集2组HRV数据进行比较分析。结果站桩态,试验组窦性心搏间标准差(SDNN)、相邻正常窦性心搏间期差值的均方根(RMSSD)和相差50 ms以上相邻窦性心搏间期数占窦性心搏间期总数的百分比(PNN50)均较前升高,且试验前后差异具有统计学意义(P<0.05);对照组干预前后差异无统计学意义(P>0.05)。试验组标化低频功率(LFn)降低,标化高频功率(HFn)升高,且试验前后,LFn、HFn、LF/HF变化差异具有统计学意义(P<0.05);对照组各时段LFn、HFn、LF/HF变化差异无统计学意义。结论三圆式站桩功对练习者的HRV指标水平影响显著,具体表现为提高副交感神经活性、降低交感神经活性,且有益于自主神经的平衡。其对焦虑状态的缓解效应值得进一步研究。
Objective To explore the effects of pole-standing qigong on anxiety via investigating the heart rate variability(HRV) time and frequency domain parameters. Methods College students(Self-Rating Anxiety Scale, SAS≥50) as volunteer subjects were recruited and randomly divided into experimental group and control group at 1∶1 ratio. The experimental group received standing qigong intervention for 10 weeks(≥5 times a week) while the control group did not receive any intervention. Before and after standing qigong intervention, The HRV results of both groups were collected for comparative analysis. Results The SDNN, RMSSD and pNN50 of the experimental group were higher than resting state before standing status, and this difference before and after intervention was statistically significant(P<0.05). LFn was reduced while HFn increased in the experimental group. The difference between LFn, HFn, LFn/HFn before and after the study was statistically significant(P<0.05) in the experimental group but not significant in the control group. Conclusion The pole-standing qigong intervention has a significant effect on the HRV in the practitioners, which is characterized by improved parasympathetic nerve activity, reduced sympathetic nerve activity, and benefiting from the balance of autonomic function. Its relieving effect on anxiety status warrants further study.
