背景技术背景：骨盆底肌肉（PFM）练习期间轴向伸展对骨盆底位移和腹肌活动的影响尚不清楚。目的：阐明PFM任务期间坐姿轴向伸展对骨盆底位移和腹肌活动的影响。方法：骨盆底移位，腹部肌肉活动，对34名健康男性青年在静息和轴向伸展坐姿下进行骨盆底运动时PFM的运动感觉和主观运动感觉进行了比较。在静息位和轴向伸展坐位之间，骨盆底位移无显著差异。在骨盆底凹陷时，轴向伸展位的主观动觉明显比静息坐位的主观动觉容易。骨盆底凹陷时，腹斜肌在轴向伸展时的活动高于静息坐位。轴向延伸的变化显着更大的内斜肌在升降机和在内部和外部斜肌在抑郁症比在较低的腹直肌muscules.CONCLUSION：轴向延伸在坐姿不改变骨盆底位移过程中的PFM任务。然而，轴向伸展可以有效地促进PFM的主观运动感觉和增加斜腹肌活动。
BACKGROUND: The effects of axial extension on pelvic floor displacement and abdominal muscle activity during pelvic floor muscle (PFM) exercises are not well known.OBJECTIVE: To clarify the effect of sitting axial extension on pelvic floor displacement and abdominal muscle activity during a PFM task.METHODS: Pelvic floor displacement, abdominal muscle activity, and subjective kinesthesia of the PFM were compared between the resting and axial-extended sitting positions during a pelvic floor task in 34 healthy young men.RESULTS: No significant difference in pelvic floor displacement was observed between the resting and axial extension sitting position. Subjective kinesthesia was significantly easier to perform in axial extension than in resting sitting position during pelvic floor depression. Abdominal oblique muscle activity was higher in axial extension than in resting sitting position during pelvic floor depression. The changes in axial extension were significantly greater in the internal oblique muscles during elevation and in the internal and external oblique muscles during depression than in the lower rectus abdominis muscles.CONCLUSION: Axial extension in the sitting position does not change pelvic floor displacement during the PFM task. However, axial extension may be effective in facilitating subjective kinesthesia of PFM and in increasing oblique abdominal muscle activity.
