is a fast pace respiratory exercise or , which is supposed to be practiced by yogis to clean their brain. are well known to improve heart rate variability (HRV) ultimately leading to better autonomic functions. Other studies have observed the immediate effect of on various neurological (brain and spine) and autonomic functions, but their results are varied and inconclusive.
The aim of this study is to find out the changes in HRV and brain waves during and after practice of as compared with the baseline values of different parameters.
Various parameters were measured at baseline, during and after with the help of Dinamika HRV-Advanced HRV Test System, Moscow, Russia. Statistical analysis was accomplished employing repeated measures analysis of variance with Bonferroni post-hoc analysis and Holm's multiple comparisons using the Version 28.0.0.0 of the Statistical Package for the Social Sciences (SPSS) for Windows (190) SPSS Inc., Chicago.
We found that during and after , changes in HRV were significant in time and frequency domain showing parasympathetic withdrawal and insignificant changes in brain waves as compared with reference point values.
is initially energizing, cleansing, and heating. There occurs parasympathetic withdrawal and sympathetic activation during . There is an increase gamma wave activation post showing control of the default mode network.
是一种快节奏呼吸练习，瑜伽修行者通过它来净化大脑。众所周知，其能改善心率变异性（HRV），最终带来更好的自主神经功能。其他研究观察了其对各种神经（大脑和脊柱）及自主神经功能的即时影响，但其结果各异且尚无定论。
本研究旨在找出与不同参数的基线值相比，在练习期间及之后HRV和脑电波的变化。
借助俄罗斯莫斯科的Dinamika HRV - 高级HRV测试系统，在基线、练习期间及之后测量各种参数。使用适用于Windows的社会科学统计软件包（SPSS）28.0.0.0版（SPSS Inc., Chicago）进行重复测量方差分析，并采用Bonferroni事后分析和Holm多重比较进行统计分析。
我们发现，在练习期间及之后，HRV在时域和频域的变化显著，显示出副交感神经撤离，与参考点值相比，脑电波变化不显著。
最初具有提神、净化和升温作用。练习期间会出现副交感神经撤离和交感神经激活。练习后γ波激活增加，表明默认模式网络得到控制。
