This study investigated the influence of yoga breathing techniques (YBT) on physiological and perceptual responses during sub-maximal treadmill running. Runners (n = 21) of various fitness (VO2max 48.4 ± 9.5 ml/kg/min) were assigned to Yoga (YG) or control (CT) group before completing pre/post treadmill trials where velocity was self-selected to produce an RPE 4 and RPE 7 (10 min each). YG (n =11) practiced three styles of YBT (30 min/day, 6 days/wk) for 3 consecutive wks. Self-selected running velocity for YG improved significantly at both prescribed RPE 4 (pre 157.63 ± 26.20 M/min, post 181.02 ± 24.22 M/min, p = 0.01) and prescribed RPE 7 (pre 201.97 ± 31.28 M/min, post 222.68± 35.32 M/min, p = 0.01). VO2 at RPE 7 increased significantly (pre 42.6 ± 6.9 ml/kg/min, post 47.3 ± 6.2 ml/kg/min, p = 0.02), TV at RPE 7 (pre 1.81 ± 0.30, post 2.04 ± 0.41, p = 0.01), and MV at RPE 7 (pre 77.25 ± 12.42, post 91.23 ± 20.05, p = 0.01). The CT group showed no significant changes except for TV at RPE 7 (pre 1.9 ± 0.3, post 2.0 ± 0.3, p = 0.04). Current results suggest YBT positively influences running velocity regulation during self-selected running.
本研究调查了瑜伽呼吸技巧（YBT）对次最大强度跑步机跑步期间生理和感知反应的影响。在完成跑步机前/后测试之前，将不同体能水平（最大摄氧量48.4±9.5毫升/千克/分钟）的跑步者（n = 21）分为瑜伽（YG）组或对照组（CT），测试中速度由受试者自行选择，以产生主观用力程度（RPE）为4和RPE为7的状态（各10分钟）。YG组（n = 11）连续3周每天练习三种YBT方式（每天30分钟，每周6天）。YG组在规定的RPE为4时（预测试157.63±26.20米/分钟，后测试181.02±24.22米/分钟，p = 0.01）和规定的RPE为7时（预测试201.97±31.28米/分钟，后测试222.68±35.32米/分钟，p = 0.01），自行选择的跑步速度均显著提高。RPE为7时的最大摄氧量显著增加（预测试42.6±6.9毫升/千克/分钟，后测试47.3±6.2毫升/千克/分钟，p = 0.02），RPE为7时的潮气量（预测试1.81±0.30，后测试2.04±0.41，p = 0.01）以及RPE为7时的每分通气量（预测试77.25±12.42，后测试91.23±20.05，p = 0.01）。CT组除RPE为7时的潮气量外（预测试1.9±0.3，后测试2.0±0.3，p = 0.04）无显著变化。当前结果表明，YBT对自行选择跑步过程中的跑步速度调节有积极影响。
