There is very little evidence available on the effects of yoga-based breathing practices on response inhibition. The current study used stop-signal paradigm to assess the effects of yoga breathing with intermittent breath holding (YBH) on response inhibition among healthy volunteers.
Thirty-six healthy volunteers (17 males + 19 females), with mean age of 20.31 ± 3.48 years from a university, were recruited in a within-subject repeated measures (RM) design. The recordings for stop signal task were performed on three different days for baseline, post-YBH, and post yogic breath awareness (YBA) sessions. Stop-signal reaction time (SSRT), mean reaction time to go stimuli (go RT), and the probability of responding on-stop signal trials (p [r/s]) were analyzed for 36 volunteers using RM analysis of variance.
SSRT reduced significantly in both YBH (218.33 ± 38.38) and YBA (213.15 ± 37.29) groups when compared to baseline (231.98 ± 29.54). No significant changes were observed in go RT and p (r/s). Further, the changes in SSRT were not significantly different among YBH and YBA groups.
Both YBH and YBA groups were found to enhance response inhibition in the stop-signal paradigm. YBH could be further evaluated in clinical settings for conditions where response inhibition is altered.
关于基于瑜伽的呼吸练习对反应抑制的影响,现有证据非常少。本研究采用停止信号范式评估间歇性屏气的瑜伽呼吸法(YBH)对健康志愿者反应抑制的影响。
招募了36名来自某大学的健康志愿者(17名男性 + 19名女性),平均年龄为20.31 ± 3.48岁,采用被试内重复测量(RM)设计。在三个不同的日子进行停止信号任务的记录,分别为基线期、YBH后和瑜伽呼吸觉知(YBA)后阶段。使用RM方差分析对36名志愿者的停止信号反应时间(SSRT)、对启动刺激的平均反应时间(启动RT)以及在停止信号试验中做出反应的概率(p[r/s])进行分析。
与基线期(231.98 ± 29.54)相比,YBH组(218.33 ± 38.38)和YBA组(213.15 ± 37.29)的SSRT均显著降低。启动RT和p[r/s]未观察到显著变化。此外,YBH组和YBA组之间SSRT的变化无显著差异。
发现YBH组和YBA组在停止信号范式中均增强了反应抑制。YBH可在反应抑制改变的临床环境中进一步评估。
