A randomized controlled pilot study was carried out to determine the effect of a 15-minute practice of ANB exercise on experimentally induced anxiety using the simulated public speaking model in yoga-naïve healthy young adults. Thirty consenting medical students were equally divided into test and control groups. The test group performed alternate nostril breathing exercise for 15 minutes, while the control group sat in a quiet room before participating in the simulated public speaking test (SPST). Visual Analog Mood Scale and Self-Statements during Public Speaking scale were used to measure the mood state at different phases of the SPST. The psychometric scores of both groups were comparable at baseline. Repeated-measures ANOVA showed a significant effect of phase ( < 0.05), but group and gender did not have statistically significant influence on the mean anxiety scores. However, the test group showed a trend towards lower mean scores for the anxiety factor when compared with the control group. Considering the limitations of this pilot study and the trend seen towards lower anxiety in the test group, alternate nostril breathing may have potential anxiolytic effect in acute stressful situations. A study with larger sample size is therefore warranted. This trial is registered with CTRI/2014/03/004460.
一项随机对照初步研究旨在确定在瑜伽新手健康年轻成年人中，使用模拟公众演讲模型，进行 15 分钟的交替鼻孔呼吸练习对实验性诱导焦虑的影响。将 30 名同意参加的医学生平均分为实验组和对照组。实验组进行 15 分钟的交替鼻孔呼吸练习，而对照组在参加模拟公众演讲测试（SPST）前坐在安静的房间里。视觉模拟情绪量表和公众演讲时的自我陈述量表用于测量 SPST 不同阶段的情绪状态。两组的心理计量评分在基线时具有可比性。重复测量方差分析显示阶段有显著影响（<0.05），但组和性别对平均焦虑评分没有统计学上的显著影响。然而，与对照组相比，实验组的焦虑因子的平均得分呈下降趋势。考虑到这项初步研究的局限性以及实验组中焦虑程度降低的趋势，交替鼻孔呼吸在急性应激情况下可能具有潜在的抗焦虑作用。因此，需要进行更大样本量的研究。这项试验在 CTRI/2014/03/004460 注册。
