Studies have shown that athletes have three times increased risk of urinary incontinence compared to non-athletes, in addition to anal incontinence and sexual dysfunction (SD). This study aimed to assess the sexual and pelvic floor muscle (PFM) functions and to compare these variables among female athlete runners with and without SD and to identify predictive factors that may be associated with sexual function among the athletes.
Cross-sectional study including 90 female runners, who ran ≥ 20 km/week for at least 6 months, had had sexual intercourse in the last 4 weeks and were > 18 years old. PFM function was assessed by vaginal palpation and manometry. Women also answered the International Consultation on Incontinence Questionnaire-Short Form to investigate presence of urinary incontinence. Sexual function was assessed by Female Sexual Function Index (FSFI); total scores ≤ 26.5 were considered to indicate SD. The scores of each FSFI domain and the total score were compared individually between each predictor using simple linear regression. In addition, multiple linear regression analysis was performed.
Athletes with SD presented lower PFM strength. The results of the multiple linear regression analysis among all the predictor variables, FSFI domains and total score show that the Modified Oxford Scale is a predictor for the desire, excitation, lubrication, orgasm, pain and total score domains.
Female runners with lower PFM strength presented worse sexual function regardless of age, parity, BMI and running practice time.
研究表明，与非运动员相比，运动员尿失禁风险增加两倍，此外还存在肛门失禁和性功能障碍（SD）。本研究旨在评估性功能和盆底肌肉（PFM）功能，并比较有和没有SD的女性运动员跑步者之间的这些变量，以及确定运动员中可能与性功能相关的预测因素。
横断面研究纳入90名女性跑步者，她们每周跑步≥20公里，至少持续6个月，在过去4周内有过性行为且年龄大于18岁。通过阴道触诊和压力测定评估PFM功能。女性还回答了国际尿失禁咨询问卷简表以调查尿失禁情况。通过女性性功能指数（FSFI）评估性功能；总分≤26.5被认为表明存在SD。使用简单线性回归分别比较每个预测因素之间每个FSFI领域的得分和总分。此外，进行了多元线性回归分析。
患有SD的运动员PFM力量较低。所有预测变量、FSFI领域和总分的多元线性回归分析结果表明，改良牛津量表是欲望、兴奋、润滑、性高潮、疼痛和总分领域的预测指标。
无论年龄、产次、体重指数和跑步练习时间如何，PFM力量较低的女性跑步者性功能较差。
