Abstract：
Hypopressive exercises (HE) are part of the Low Pressure Fitness training program which is widely used by physical therapists in the rehabilitation of the pelvic floor, abdominal and spinal musculature. The aim of this study was to compare the effects of HE on the sagittal lumbo-pelvic posture in athletic and non-athletic females. It was hypothesized that a 5-week training program of HE could influence lumbo-pelvic position while reducing abdominal circumference and low back pain in athletic and non-athletic females. Twenty normoweight females (mean age = 24.8 (SD 3.5) years; body mass index = 22.4 (SD 1.6) kg/m2) participated in this study. Ten athletic females were rugby players (RG), and 10 females were non-athletic (SG). Participants completed twenty minutes of HE twice weekly for 5 weeks. Before and after the intervention, two-dimension photogrammetry was used to assess lumbar lordosis and pelvic horizontal alignment. A Visual Analog Scale was used to assess low back pain and cirtometry was used to assess abdominal circumferences at umbilical, supra and infra-umbilical levels. An analysis of variance between moments revealed no significant differences in lumbar lordosis and pelvic positioning but showed significant differences for abdominal circumferences between groups. No significant differences between groups were found for other variables. Significant correlations were found between the three different abdominal circumference measurements (p > 0.05) but not between lumbar lordosis and abdominal circumferences. These preliminary findings indicate that a 5-week HE intervention displayed non-significant changes in lumbar lordosis, pelvic horizontal alignment, and low back pain but a significant reduction in abdominal circumferences in non-athletic and athletic females.
摘要：
低压性运动（HE）是低压健身训练计划的一部分，物理治疗师广泛用于盆底康复，腹部和脊髓肌肉组织。这项研究的目的是比较HE对运动和非运动女性矢状位腰骨盆姿势的影响。据推测，为期5周的HE训练计划可以影响腰骨盆位置，同时减少运动和非运动女性的腹围和腰痛。20名体重正常的女性（平均年龄=24.8（SD3.5）岁；体重指数=22.4（SD1.6）kg/m2）参加了这项研究。十名运动女性是橄榄球运动员（RG），10名女性为非运动（SG）。参与者每周两次完成20分钟的HE，持续5周。干预前后,使用二维摄影测量法评估腰椎前凸和骨盆水平排列。视觉模拟量表用于评估下背痛，而围测法用于评估脐部的腹围，上水平和脐带下水平。力矩之间的方差分析显示，腰椎前凸和骨盆定位没有显着差异，但两组之间的腹部周长有显着差异。对于其他变量，组间没有发现显着差异。在三种不同的腹围测量值之间发现了显着的相关性（p>0.05），但在腰椎前凸度和腹围之间没有显着相关性。这些初步发现表明，5周的HE干预显示腰椎前凸无明显变化，骨盆水平对齐,和腰背痛，但在非运动和运动女性的腹部周长显着减少。
