第二版美国人体力活动指南 (PAG) 部分建议进行 150 分钟的中等强度有氧体力活动。 PAG 指出，瑜伽可能有助于满足成人和老年人中等强度有氧运动的指导方针。我们的研究旨在根据心率数据客观测量参与者活动被归类为中等强度有氧活动的时间比例，并主观测量感知运动率（RPE）。参与者完成了斯坦福休闲活动分类项目，以建立基线 PAG 有氧活动合规性。然后，参与者在佩戴心率监测器的同时，以不同的节奏（节奏）和温度完成四次独立的 1 小时瑜伽课程。在课程期间和课程结束后，他们还按照修改后的 10 分制对自己的 RPE 进行了评分。根据心率监测数据和 RPE，所有参与者至少在瑜伽课程的一部分中达到中等强度的有氧活动。在所有四种班级类型中，中等强度的平均持续时间为班级的 32.75%，不同条件之间没有显着差异。仅对于热中性哈他类别来说，年龄是影响中度至剧烈体力活动时间的重要因素（p = 0.010）。根据皮尔逊相关性和克鲁斯卡尔-沃利斯检验，节奏、温度和基线活动水平并不是中度至剧烈强度体力活动所花费时间的显着因素。在室温或高温下的哈他和流瑜伽课程可用于满足 PAG 中等强度活动建议的一部分。
The 2nd edition of the Physical Activity Guidelines for Americans (PAG) recommends, in part, 150 min of moderate-intensity aerobic physical activity. The PAG states that yoga may be able to help meet the guidelines for moderate-intensity aerobic exercise for adults and older adults. Our study aims to objectively measure the proportion of time participants’ activity that is categorized as moderate-intensity aerobic activity based on heart rate data and to subjectively measure rate of perceived exertion (RPE). Participants completed the Stanford Leisure-Time Activity Categorical item to establish baseline PAG aerobic activity compliance. Participants then completed four separate 1-h yoga sessions at different tempos (cadence) and temperatures while wearing heart rate monitors. During and directly after the session they also marked their RPE on a modified 10-point scale. All participants reached moderate-intensity aerobic activity for at least some portion of a yoga session based on heart rate monitor data and RPE. The average duration of moderate intensity was 32.75% of the class across all four class types, with no significant differences by condition. Age was a significant factor in time spent in moderate-to-vigorous physical activity for only the thermo-neutral Hatha classes (p = 0.010). Tempo, temperature, and baseline activity levels were not significant factors in time spent in moderate-to-vigorous intensity physical activity based on Pearson Correlation and the Kruskal–Wallis test. Hatha and Vinyasa yoga classes, at room or hot temperatures, can be used to meet a portion of the PAG moderate-intensity activity recommendations.
