Resistive breathing practices are known to improve endurance and performance in competitive swimmers. However, the effect of Pranayama or Yogic Breathing Practices (YBP) in improving respiratory endurance and performance of competitive swimmers remains un-investigated.
To study effects of yogic breathing practices on lung functions of swimmers.
Twenty seven national and international competitive swimmers of the age range 13-20 years, with 8.29 ± 2.9 years of competitive swimming experience and practicing swimming for 9.58 ± 1.81 km everyday, were assigned randomly to either an experimental (YBP) or to wait list control group (no intervention). Outcome measures were taken on day 1 and day 30 and included (1) spirometry to measure lung function, (2) Sport Anxiety Scale-2 (SAS-2) to measure the antecedents and consequences of cognitive and somatic trait anxiety of sport performance and (3) number of strokes per breath to measure performance. The YBP group practiced a prescribed set of Yogic Breathing Practices - Sectional Breathing (Vibhagiya Pranayama), Yogic Bellows Breathing (Bhastrika Pranayama) and Alternate Nostril Breathing with Voluntary Internal Breath Holding (Nadi Shodhana with Anthar kumbhaka) for half an hour, five days a week for one month.
There was a significant improvement in the YBP group as compared to control group in maximal voluntary ventilation (p = 0.038), forced vital capacity (p = 0.026) and number of strokes per breath (p = 0.001).
The findings suggest that YBP helps to enhance respiratory endurance in competitive swimmers.
已知阻力呼吸练习可提高竞技游泳运动员的耐力和表现。然而，瑜伽呼吸法或瑜伽呼吸练习（YBP）对提高竞技游泳运动员呼吸耐力和表现的影响尚未得到研究。
研究瑜伽呼吸练习对游泳运动员肺功能的影响。
27名年龄在13 - 20岁之间的国家和国际竞技游泳运动员，有8.29±2.9年的竞技游泳经验，每天练习游泳9.58±1.81公里，被随机分为实验组（YBP）或等待名单对照组（无干预）。在第1天和第30天进行结果测量，包括：（1）通过肺活量测定法测量肺功能；（2）使用运动焦虑量表-2（SAS-2）测量运动表现中认知和躯体特质焦虑的前因和后果；（3）测量每呼吸的划水次数以评估表现。YBP组每周五天，每天半小时练习一套规定的瑜伽呼吸练习，包括分段呼吸（Vibhagiya Pranayama）、瑜伽风箱呼吸（Bhastrika Pranayama）和伴有自愿内屏息的交替鼻孔呼吸（Nadi Shodhana with Anthar kumbhaka），持续一个月。
与对照组相比，YBP组在最大自主通气量（p = 0.038）、用力肺活量（p = 0.026）和每呼吸划水次数（p = 0.001）方面有显著改善。
研究结果表明，YBP有助于提高竞技游泳运动员的呼吸耐力。
