The reaction time (RT) was assessed in two groups of healthy males, yoga group (M age = 29.0 yr.) and non-yoga or control group (M age = 29.0 yr.), with 35 participants each. The yoga group had an average experience of 6 months, while the control group was yoga-naïve. The yoga group was assessed in two sessions, (i) bhastrika pranayama or bellows breathing and (ii) breath awareness, while the control group had a single control session. The two experimental sessions, one with each type of breathing, and the control session consisted of pre- (5 min.), during (18 min.), and post-session epochs (5 min.). Assessments were made in the pre- and post-session epochs using a Multi-Operational Apparatus for Reaction Time. Following 18 min. of bhastrika pranayama there was a statistically significant reduction in number of anticipatory responses compared to before the practice. This suggests that the immediate effect of bhastrika pranayama is to inhibit unnecessary responding to stimuli.
反应时间（RT）在两组健康男性中进行评估，瑜伽组（M 年龄=29.0 岁）和非瑜伽或对照组（M 年龄=29.0 岁），每组 35 名参与者。瑜伽组的平均经验为 6 个月，而对照组则是瑜伽新手。瑜伽组在两个阶段进行评估，（i）bhastrika 呼吸法或风箱式呼吸，（ii）呼吸意识，而对照组则进行单一的对照阶段。两个实验阶段，一个阶段进行呼吸练习，一个阶段进行对照，每个阶段分为预（5 分钟）、中（18 分钟）和后（5 分钟）三个阶段。使用多操作反应时间仪器在预和后阶段进行评估。在进行 18 分钟的 bhastrika 呼吸法后，与练习前相比，预期反应的数量有统计学显著减少。这表明，bhastrika 呼吸法的即时效果是抑制对刺激的不必要反应。
