The effects of three yoga breathing practices were evaluated on performance on a letter-cancellation task which is a left-hemisphere dominant task. The three yoga breathing practices (right, left, and alternate nostril breathing) were selected because unilateral forced nostril breathing stimulates the contralateral hemisphere. There were 20 male volunteers whose ages ranged from 20 to 45 years (M age=28.4 yr., SD=5.7). All subjects were assessed before and after four sessions, i.e., right nostril yoga breathing, left nostril yoga breathing, alternate nostril yoga breathing, and breath awareness as a control. The letter-cancellation task scores were significantly improved, i.e., there were fewer errors following right and alternate nostril yoga breathing (Wilcoxon paired signed-ranks test). The improved performance may be related to the enhancement of contralateral hemisphere function found with selective nostril breathing.
研究评估了三种瑜伽呼吸练习对字母划消任务表现的影响，该任务是一项左半球占主导的任务。选择这三种瑜伽呼吸练习（右鼻孔呼吸、左鼻孔呼吸和交替鼻孔呼吸）是因为单侧强制鼻孔呼吸会刺激对侧半球。有20名年龄在20至45岁之间的男性志愿者（平均年龄 = 28.4岁，标准差 = 5.7）。所有受试者在四个阶段前后接受评估，即右鼻孔瑜伽呼吸、左鼻孔瑜伽呼吸、交替鼻孔瑜伽呼吸以及作为对照的呼吸觉知。字母划消任务得分显著提高，即右鼻孔和交替鼻孔瑜伽呼吸后错误减少（威尔科克森配对符号秩检验）。表现的改善可能与选择性鼻孔呼吸所发现的对侧半球功能增强有关。
