This study was aimed at exploring the biomechanical characteristics of the lower extremity amongst three typical yoga manoeuvres. A total of thirteen experienced female yoga practitioners were recruited in the current study; they were all certified with the Yoga Alliance. A three-dimensional motion capture system with 10 cameras combined with four synchronised force plates was used to collect kinematics of the lower extremity and ground reactive force whilst the participants performed the crescent lunge pose, warrior II pose, and triangle pose. One-way repeated ANOVA was used in exploring the differences amongst the three yoga movements, and the significance was set to . The triangle pose performed the largest range of motion (ROM) of the hip (), knee (), and ankle () in the sagittal plane and the hip (), knee (), and ankle () in the frontal plane amongst the three manoeuvres (). No significant difference was found for the hip and ankle joint moment amongst the three manoeuvres (). Knee joint travelled into 9.5° of extension and slight adduction of 1.94° whilst expressing the largest knee joint adduction moments () in the triangle pose. The distribution of the angular impulse of the lower limb joints indicated that the hip joint contributed significantly the most in the sagittal and frontal planes of the three yoga manoeuvres (), ranging from 51.67% to 70.56%. Results indicated that triangle pose may be superior to the other two manoeuvres, which improved hip joint ROM, strength, and dynamic stability. However, knee injuries such as osteoarthritis (OA) should be considered because of the large knee extensor angle and adductor moments.

三种典型瑜伽动作下肢生物力学特征

本研究旨在探索三种典型瑜伽动作中下肢的生物力学特征。本研究共招募了 13 名经验丰富的女性瑜伽练习者；他们都获得了瑜伽联盟的认证。一个带有 10 个摄像头和四个同步测力板的三维运动捕捉系统用于收集下肢和地面反作用力的运动学，同时参与者执行新月弓步姿势、战士 II 姿势和三角形姿势。单向重复方差分析用于探索三种瑜伽动作之间的差异，其意义设置为. 三角形姿势执行髋关节的最大运动范围（ROM）（),膝盖 ()和脚踝 ()在矢状面和髋部 (),膝盖 ()和脚踝 ()在三个动作中的正面平面 (）。三种动作之间的髋关节和踝关节力矩没有显着差异（）。膝关节伸展 9.5°，轻微内收 1.94°，同时表现出最大的膝关节内收力矩（)的三角形姿势。下肢关节角冲动的分布表明，髋关节在三个瑜伽动作的矢状面和额面中贡献最大。)，范围从 51.67% 到 70.56%。结果表明，三角形姿势可能优于其他两种动作，这改善了髋关节 ROM、力量和动态稳定性。然而，由于膝关节伸肌角和内收肌力矩较大，应考虑膝关节损伤，如骨关节炎 (OA)。
