To determine and compare activation of core muscles during yoga to traditional back exercises.
Surface electromyography was used to quantify activation of the rectus abdominis (RA), abdominal obliques (AO), lumbar extensors (LE), and gluteus maximus (GMX) during four yoga poses. Data were expressed as 100% of a maximum voluntary isometric contraction. Separate analyses of variance with repeated measures were used to compare muscle activity across each exercise.
Subjects generated greater RA (P < 0.0001) and AO (P < 0.0001) activity during the Plank. They generated greater AO activity (P < 0.0001) during the Upward-Facing Dog than the Chair and Dominant-Side Warrior 1. LE activity was greatest (P < 0.0001) during the Chair. GMX activity was similar (P = 0.09) during all exercises.
Yoga poses may help improve core endurance and strength. Clinicians may use these data when developing and implementing an evidence-based core exercise program for individuals who prefer a yoga treatment strategy.
确定并比较瑜伽和传统背部锻炼中核心肌肉的激活情况。
使用表面肌电图来量化在四个瑜伽姿势下，腹直肌（RA）、腹斜肌（AO）、腰椎伸肌（LE）和臀大肌（GMX）的激活情况。数据表示为最大等长收缩的 100%。采用重复测量方差分析来比较每项运动中的肌肉活动。
与椅子和优势侧战士 1 相比，受试者在平板支撑中产生更大的 RA（P<0.0001）和 AO（P<0.0001）活动。在向上狗中，他们产生更大的 AO 活动（P<0.0001）。在椅子中，LE 活动最大（P<0.0001）。GMX 活动在所有运动中相似（P=0.09）。
瑜伽姿势可能有助于提高核心耐力和力量。临床医生可以在为喜欢瑜伽治疗策略的个人制定和实施基于证据的核心运动方案时使用这些数据。
