To develop a method that describes the physical activity completed during yoga, and to use this method to compare three different yoga video categories: weight loss, beginner, and stress relief/meditation.
This study conducted content analysis of commercially available yoga videos in which pre-determined characteristics of yoga routines were recorded. Outcome measures included the yoga routine characteristics of: duration of each yoga routine, number of completed poses, body position of each pose, and pose rate.
Twenty-two routines from yoga videos were analyzed. Duration of routine between the three different categories was not significantly different. There were significant differences between the video categories based on the characteristics of total number of poses and the pose rate, with weight loss routines having the highest values compare to beginner routines and stress relief/meditation (total number of poses: 74.1, 34.3, 25.6 poses, p < 0.05; Pose rate: 2.5m 1.5, 1.1 poses/min, p < 0.05, respectively). Additionally, differences were observed between body postures in poses with weight loss videos including more standing poses (38.8, 17.0, 5.7 poses, p < 0.05, respectively) and a lower percentage of seated (9.9%, 15.8%, 39.0%, p < 0.05, respectively) and supine poses (10.9%, 18.5%, 28.8%, p < 0.05, respectively) compared to the beginner and stress/meditation videos.
The characteristics of total poses, pose rate, and total standing poses showed significant differences between different styles of yoga. Further research should be conducted to validate these characteristics as an intensity measures and to assess if these characteristics have variations between different yoga styles.
开发一种描述瑜伽运动中完成的体力活动的方法，并使用该方法比较三种不同的瑜伽视频类别：减肥、初级和减压/冥想。
本研究对商业上可用的瑜伽视频进行了内容分析，其中记录了瑜伽常规的预定特征。结果测量包括瑜伽常规的以下特征：每个瑜伽常规的持续时间、完成的姿势数量、每个姿势的身体位置和姿势频率。
分析了来自瑜伽视频的 22 个常规。三种不同类别的常规持续时间没有显著差异。根据总姿势数量和姿势频率的特征，视频类别之间存在显著差异，减肥常规与初级常规和减压/冥想相比具有最高值（总姿势数量：74.1、34.3、25.6 个姿势，p<0.05；姿势频率：2.5m 1.5、1.1 个姿势/分钟，p<0.05，分别）。此外，在减肥视频中观察到姿势的身体姿势之间存在差异，包括更多的站立姿势（38.8、17.0、5.7 个姿势，p<0.05，分别）和较低比例的坐姿（9.9%、15.8%、39.0%，p<0.05，分别）和仰卧姿势（10.9%、18.5%、28.8%，p<0.05，分别）与初级和减压/冥想视频相比。
不同瑜伽风格之间的总姿势数量、姿势频率和总站立姿势特征存在显著差异。应进一步开展研究，以验证这些特征作为强度测量指标，并评估这些特征在不同瑜伽风格之间是否存在差异。
