BACKGROUND
Long-term alternate nostril breathing (ANB) has been shown to enhance autonomic control of the heart by increasing parasympathetic modulation. However, there is no information on the immediate effects of ANB on autonomic control compared to paced breathing (PB) at the same rate in individuals who are inexperienced with yogic breathing.
AIM
To examine cardiac autonomic modulation following ANB in comparison to that following PB in individuals who were inexperienced in ANB.
MATERIALS AND METHODS
Twenty healthy individuals (22.3 ± 2.9 years) with no prior experience with ANB engaged in
RESULTS
Analysis of covariance revealed lnTP, lnLF and lnHF were greater during both post-ANB and post-PB compared to PRE (P<0.05). MAP and lnLF/lnHF did not significantly differ between conditions.
CONCLUSIONS
These data suggest that there was an immediate increase in cardiac autonomic modulation following ANB and PB without a shift in autonomic balance in individuals inexperienced with yogic breathing. To our knowledge, this is the first investigation to investigate the autonomic effects of ANB in this population and also to compare the effects of ANB and PB at the same respiratory rate.
背景
长期交替鼻孔呼吸（ANB）已被证明可通过增加副交感神经调节来增强心脏的自主控制。然而，对于没有瑜伽呼吸经验的个体，与相同速率的节律性呼吸（PB）相比，ANB对自主控制的即时影响尚无相关信息。
目的
在没有ANB经验的个体中，比较ANB后与PB后的心脏自主神经调节。
材料与方法
20名无ANB经验的健康个体（22.3±2.9岁）参与……
结果
协方差分析显示，与预试验（PRE）相比，ANB后和PB后的lnTP、lnLF和lnHF均更高（P<0.05）。不同条件下MAP和lnLF/lnHF无显著差异。
结论
这些数据表明，在没有瑜伽呼吸经验的个体中，ANB和PB后心脏自主神经调节立即增加，且自主神经平衡未发生改变。据我们所知，这是首次在该人群中研究ANB的自主神经效应，并比较相同呼吸速率下ANB和PB的效果。
