Abstract

Attention was influenced by yoga breathing in previously published research. Each yoga breathing practice uniquely modifies specific breath characteristics. Differences in the study designs, assessment methods and interventions resulted in difficulty in comparing effects between yoga breathing practices. This study aimed (i) to compare four yoga breathing practices on attention using an auditory oddball task and (ii) to determine cardiac autonomic activity associated with attention using heart rate variability. P300 event related potential was recorded simultaneously with heart rate variability before and after 18-minute periods each of (i) high frequency yoga breathing (with increased breath frequency), (ii) bellows yoga breathing (with increased depth of respiration), (iii) alternate nostril yoga breathing (with alternate nostril patency), (iv) bumblebee yoga breathing (with prolonged exhale), (v) breath awareness (with attention to the breath) and (vi) quiet seated rest as control in 38 yoga experienced males (average age ± SD; 24.08 ± 4.01 years). The six sessions were on separate, randomly allocated days. The P300 peak amplitude recorded at Pz was significantly increased after four yoga breathing practices (Bonferroni adjusted post-hoc tests, repeated measures ANOVA). No significant changes were noted in heart rate variability following yoga breathing or control sessions. These findings suggest that the four yoga breathing practices increase the attentional neural resources engaged for this auditory oddball task, irrespective of the characteristic of breath uniquely regulated in the four yoga breathing practices.

P300遵循四个自愿调节的瑜伽呼吸练习和呼吸意识。
在先前发表的研究中,注意力受到瑜伽呼吸的影响。每个瑜伽呼吸练习都独特地修改特定的呼吸特征。研究设计、评估方法和干预措施的差异导致很难比较瑜伽呼吸练习的效果。本研究的目的是(i)比较四种瑜伽呼吸练习对注意力的影响,使用听觉怪球任务;(ii)使用心率变异性来确定与注意力相关的心脏自主神经活动。同时记录P300事件相关电位与心率变异性分别在(i)高频瑜伽呼吸(呼吸频率增加),(ii)风箱瑜伽呼吸(呼吸深度增加),(iii)交替鼻孔瑜伽呼吸(交替鼻孔开放),(iv)大黄蜂瑜伽呼吸(呼气时间延长),(v)呼吸意识(注意呼吸)和(vi)安静坐着休息作为对照,38名有瑜伽经验的男性(平均年龄±SD;(24.08±4.01年)。这六次会议分别在随机分配的日期进行。四次瑜伽呼吸练习后,P300在Pz记录的峰值幅度显著增加(Bonferroni调整后的事后检验,重复测量方差分析)。在瑜伽呼吸或控制课程后,心率变异性没有明显变化。这些发现表明,四种瑜伽呼吸练习增加了参与这种听觉怪异任务的注意力神经资源,而不考虑四种瑜伽呼吸练习中独特调节的呼吸特征。
