Abstract

OBJECTIVE

To compare core activation during yoga between males and females.

METHODS

Surface electromyography was used to quantify rectus abdominis (RA), abdominal obliques (AO), lumbar extensors (LE), and gluteus maximus (GMX) activation during four yoga poses. Data were expressed as 100% of a maximum voluntary isometric contraction. Mixed-model 2 × 2 analyses of variance with repeated measures were used to determine between-sex differences in muscle activity.

RESULTS

Females generated greater RA activity than males during the High Plank (P < 0.0001) and Dominant-Side Warrior 1 (P = 0.017). They generated greater AO (P < 0.0001) and GMX (P = 0.004) activity during the High Plank (P < 0.0001). No between-sex EMG activity differences existed for the Chair and Upward Facing Dog.

CONCLUSION

Findings have provided preliminary evidence for between-sex differences in muscle activation during yoga poses. Clinicians should consider such differences when prescribing yoga to improve muscle strength and endurance.

摘要

目的

比较男性和女性瑜伽时核心部位的激活情况。

方法

使用表面肌电图来量化在四个瑜伽姿势中腹直肌（RA）、腹外斜肌（AO）、腰椎伸肌（LE）和臀大肌（GMX）的激活情况。数据以最大等长收缩的 100%表示。采用混合模型 2×2 方差分析和重复测量来确定肌肉活动的性别差异。

结果

女性在高位平板式（High Plank）和优势侧战士一式（Dominant-Side Warrior 1）中产生的 RA 活性大于男性（P<0.0001）。她们在高位平板式中产生的 AO（P<0.0001）和 GMX（P=0.004）活性大于男性。在椅子式（Chair）和上犬式（Upward Facing Dog）中，男女之间的肌电图活动没有差异。
