We examined pelvic floor muscles (PFM) activity (%MVC) in twenty nulliparous women by body position during exercise as well as the activation of abdominal muscles and the gluteus maximus during voluntary contractions of the PFMs. Pelvic floor muscle activity was recorded using a vaginal probe during five experimental trials. Activation of transversus abdominis, rectus abdominis, and gluteus maximus during voluntary PFM contractions was also assessed. Significant differences in mean normalized amplitudes of baseline PFM activity were revealed between standing and lying (P < 0.00024) and lying and ball-sitting positions (P < 0.0053). Average peak, average time before peak, and average time after peak did not differ significantly during the voluntary contractions of the PFMs. Baseline PFM activity seemed to depend on the body position and was the highest in standing. Pelvic floor muscles activity during voluntary contractions did not differ by position in continent women. Statistically significant differences between the supine lying and sitting positions were only observed during a sustained 60-second contraction of the PFMs.
我们通过运动时的体位，对20名未生育女性的盆底肌（PFM）活动（%MVC）以及盆底肌自主收缩期间腹肌和臀大肌的激活情况进行了检查。在五项实验中，使用阴道探头记录盆底肌活动。同时评估了盆底肌自主收缩期间腹横肌、腹直肌和臀大肌的激活情况。结果显示，站立位与卧位（P < 0.00024）以及卧位与球坐体位之间，盆底肌活动的平均标准化基线幅度存在显著差异（P < 0.0053）。在盆底肌自主收缩期间，平均峰值、峰值前平均时间和峰值后平均时间无显著差异。盆底肌基线活动似乎取决于体位，站立位时最高。在尿失禁女性中，盆底肌自主收缩期间的活动不受体位影响。仅在盆底肌持续60秒收缩期间，观察到仰卧位和坐位之间存在统计学显著差异。
