Abstract：
UNASSIGNED: Traditional yoga texts describe \"cross nostril breathing,\" with inhalation and exhalation through different nostrils. Previous research reported no clear differences in oxygen consumption during uninostril breathing (i.e., inhalation and exhalation through the same nostril), hence not supporting right and left uninostril breathing as activating or relaxing, respectively, with no research on oxygen consumed in \"cross nostril breathing.\"
UNASSIGNED: Oxygen consumed during \"cross nostril breathing\" was measured in healthy participants (n = 47, males, 26.3 ± 6.4 years). Five sessions (viz., right nostril inspiration yoga breathing [RNIYB], left nostril inspiration yoga breathing [LNIYB], alternate nostril yoga breathing [ANYB], breath awareness (BAW), and quiet rest (QR) were conducted on separate days in random order. Sessions were 33 min in duration with pre, during, and post states.
UNASSIGNED: Volume of oxygen consumed (VO2) and carbon dioxide eliminated (VCO2) increased during RNIYB (9.60% in VO2 and 23.52% in VCO2), LNIYB (9.42% in VO2 and 21.20% in VCO2) and ANYB (10.25% in VO2 and 22.72% in VCO2) with no significant change in BAW and QR. Diastolic blood pressure decreased during BAW and QR and after all five sessions (P < 0.05; in all cases). All comparisons were with the respective preceding state.
UNASSIGNED: During the three yoga breathing practices, the volume of oxygen consumed increased irrespective of the nostril breathed through, possibly associated with (i) conscious regulation of the breath; (ii) attention directed to the breath, and (iii) \"respiration-locked cortical activation.\" Restriction of the study to males reduces the generalizability of the findings.

摘要：
■传统瑜伽文本描述“交叉鼻孔呼吸，通过不同的鼻孔吸入和呼出。先前的研究报告说，在uninostril呼吸期间的耗氧量没有明显差异(即，通过同一鼻孔吸气和呼气)，因此，不支持左、右脚呼吸作为激活或放松，分别,没有研究“交叉鼻孔呼吸”消耗的氧气。
■在健康参与者（n=47，男性，26.3±6.4年）。五次会议（即,右鼻孔灵感瑜伽呼吸[RNIYB]，左鼻孔灵感瑜伽呼吸[LNIYB]，交替鼻孔瑜伽呼吸[ANYB]，呼吸意识(BAW),和安静休息(QR)按随机顺序在不同的日子进行。会议持续时间为33分钟，during,和张贴状态。
■在RNIYB期间消耗的氧气（VO2）和消除的二氧化碳（VCO2）的体积增加（VO2为9.60％，VCO2为23.52％），LNIYB（VO2为9.42％，VCO2为21.20％）和ANYB（VO2为10.25％，VCO2为22.72％），BAW和QR无明显变化。在BAW和QR期间以及所有五个疗程后，舒张压均降低（P<0.05；在所有情况下）。所有比较均与各自的前一状态进行。
■在三个瑜伽呼吸练习中，消耗的氧气量增加，与鼻孔呼吸无关，可能与（i）有意识地调节呼吸有关；（ii）注意呼吸，和（iii）“呼吸锁定皮层激活。“这项研究仅限于男性，降低了研究结果的普遍性。
