Objective Stress urinary incontinence (SUI) is common among females during functional fitness training, such as CrossFit. The aim of this study was to assess the effect of pelvic floor muscle training (PFMT) on SUI in female functional fitness exercisers. Methods This was an assessor-blinded randomised controlled trial with a PFMT group (n=22) and a control group (n=25). The PFMT group followed a 16-week home-training programme with 3 sets of 8–12 maximum pelvic floor muscle (PFM) contractions daily and weekly follow-up/reminders by phone. The primary outcome was change in a total score of the International Consultation on Incontinence Questionnaire-Urinary Incontinence Short Form (ICIQ-UI-SF). The secondary outcomes were perceived change of symptoms of SUI, change of PFM strength measured by vaginal manometry and symptoms of anal incontinence (AI) and pelvic organ prolapse (POP). Results 47 women, mean age of 33.5 years (SD: 8.1), participated. At 16 weeks, there was a mean difference between groups of −1.4 (95% CI: −2.6 to −0.2) in the change of the ICIQ-UI-SF score in favour of the PFMT group. The PFMT group completed a mean of 70% (SD: 23) of the prescribed protocol. 64% in the PFMT group versus 8% in the control group reported improved symptoms of SUI (p<0.001, relative risk: 7.96, 95% CI, 2.03 to 31.19). There were no group differences in the change of PFM strength or AI/POP symptoms. Conclusion A 16-week home-training programme of the PFM led to improvements in SUI in female functional fitness exercisers. However, PFM strength and AI and POP symptoms did not improve significantly in the PFMT group compared with the control group. Data are available upon reasonable request.

女性功能健身锻炼者的盆底肌肉训练：评估者盲法随机对照试验

目的 压力性尿失禁 (SUI) 在功能性健身训练（例如 CrossFit）期间在女性中很常见。本研究的目的是评估盆底肌肉训练 (PFMT) 对女性功能健身锻炼者 SUI 的影响。方法 这是一项评估者盲法随机对照试验，其中包括 PFMT 组 (n=22) 和对照组 (n=25)。 PFMT 组遵循为期 16 周的家庭训练计划，每天进行 3 组 8-12 次最大骨盆底肌肉 (PFM) 收缩，每周通过电话进行跟踪/提醒。主要结果是国际尿失禁咨询问卷-尿失禁简表（ICIQ-UI-SF）总分的变化。次要结果是 SUI 症状的感知变化、通过阴道测压测量的 PFM 强度变化以及肛门失禁 (AI) 和盆腔器官脱垂 (POP) 的症状。结果 47 名女性参与，平均年龄 33.5 岁（SD：8.1）。第 16 周时，ICIQ-UI-SF 评分的变化有利于 PFMT 组，各组之间的平均差异为 -1.4（95% CI：-2.6 至 -0.2）。 PFMT 组平均完成了规定方案的 70%（SD：23）。 PFMT 组中有 64% 的人报告 SUI 症状有所改善，而对照组中有 8% 的人报告 SUI 症状有所改善（p<0.001，相对风险：7.96，95% CI，2.03 至 31.19）。 PFM 强度或 AI/POP 症状的变化没有组间差异。结论 PFM 为期 16 周的家庭训练计划改善了女性功能性健身锻炼者的 SUI。然而，与对照组相比，PFMT 组的 PFM 强度以及 AI 和 POP 症状没有显着改善。数据可根据合理要求提供。
