人们对典型的哈他瑜伽的新陈代谢和心率反应知之甚少。这项研究的目的是1)确定使用各种姿势的典型瑜伽练习是否符合改善和保持健康和心血管健康所需的体力活动水平的当前推荐水平；2)确定瑜伽跨时段代谢成本的可靠性；3)比较瑜伽练习和跑步机步行的代谢成本。在这项观察性研究中，20名中高级瑜伽练习者，年龄31.4±8.3岁，戴着心率监测器在人体呼吸室(间接量热计)内进行常规锻炼。锻炼常规包括30分钟的静坐，56分钟的初学者水平的哈他瑜伽通过视频进行，以及10分钟的跑步机步行，分别为3.2和4.8公里每小时。测量指标为平均耗氧量(VO2)、心率(HR)、预测最大心率百分比(%MHR)、代谢当量(METS)和能量消耗(Kcal)。7名受试者重复了这一方案，以确定测量的可靠性。在整个瑜伽过程中，VO2、HR、%MHR、METS和能量/分钟的平均值分别为0.6 L/公斤/分钟、93.2次/分钟、49.4%、2.5和3.2千卡/分钟。结果显示，在整个瑜伽训练过程中，卡路里、蛋氨酸和%MHR的ICC(2，1)平均值分别为0.979和0.973，以及0.865。瑜伽在整个疗程中的平均代谢成本代表着低水平的体力活动，类似于以每小时3.2公里的速度在跑步机上行走，不符合改善或保持健康或心血管健康的体力活动水平的建议。瑜伽练习包括超过最低10分钟的太阳敬礼姿势，可能会贡献一部分足够剧烈的体力活动，以改善身体不健康或久坐的人的心肺健康。测量瑜伽过程中的能量消耗是非常可靠的。
Little is known about the metabolic and heart rate responses to a typical hatha yoga session. The purposes of this study were 1) to determine whether a typical yoga practice using various postures meets the current recommendations for levels of physical activity required to improve and maintain health and cardiovascular fitness; 2) to determine the reliability of metabolic costs of yoga across sessions; 3) to compare the metabolic costs of yoga practice to those of treadmill walking. In this observational study, 20 intermediate-to-advanced level yoga practitioners, age 31.4 ± 8.3 years, performed an exercise routine inside a human respiratory chamber (indirect calorimeter) while wearing heart rate monitors. The exercise routine consisted of 30 minutes of sitting, 56 minutes of beginner-level hatha yoga administered by video, and 10 minutes of treadmill walking at 3.2 and 4.8 kph each. Measures were mean oxygen consumption (VO2), heart rate (HR), percentage predicted maximal heart rate (%MHR), metabolic equivalents (METs), and energy expenditure (kcal). Seven subjects repeated the protocol so that measurement reliability could be established. Mean values across the entire yoga session for VO2, HR, %MHR, METs, and energy/min were 0.6 L/kg/min; 93.2 beats/min; 49.4%; 2.5; and 3.2 kcal/min; respectively. Results of the ICCs (2,1) for mean values across the entire yoga session for kcal, METs, and %MHR were 0.979 and 0.973, and 0.865, respectively. Metabolic costs of yoga averaged across the entire session represent low levels of physical activity, are similar to walking on a treadmill at 3.2 kph, and do not meet recommendations for levels of physical activity for improving or maintaining health or cardiovascular fitness. Yoga practice incorporating sun salutation postures exceeding the minimum bout of 10 minutes may contribute some portion of sufficiently intense physical activity to improve cardio-respiratory fitness in unfit or sedentary individuals. The measurement of energy expenditure across yoga sessions is highly reliable.
