Pelvic Floor Muscle Activity and Urinary Incontinence in Weight-Bearing Female Athletes vs. Non-Athletes:

Is Physical Activity Good or Bad for the Female Pelvic Floor? A Narrative Review

More women participate in sports than ever before and the proportion of women athletes at the Olympic Games is nearly 50%. The pelvic floor in women may be the only area of the body where the positive effect of physical activity has been questioned. The aim of this narrative review is to present two widely held opposing hypotheses on the effect of general exercise on the pelvic floor and to discuss the evidence for each. Hypothesis 1: by strengthening the pelvic floor muscles (PFM) and decreasing the levator hiatus, exercise decreases the risk of urinary incontinence, anal incontinence and pelvic organ prolapse, but negatively affects the ease and safety of childbirth. Hypothesis 2: by overloading and stretching the PFM, exercise not only increases the risk of these disorders, but also makes labor and childbirth easier, as the PFM do not obstruct the exit of the fetus. Key findings of this review endorse aspects of both hypotheses. Exercising women generally have similar or stronger PFM strength and larger levator ani muscles than non-exercising women, but this does not seem to have a greater risk of obstructed labor or childbirth. Additionally, women that specifically train their PFM while pregnant are not more likely to have outcomes associated with obstructed labor. Mild-to-moderate physical activity, such as walking, decreases the risk of urinary incontinence but female athletes are about three times more likely to have urinary incontinence compared to controls. There is some evidence that strenuous exercise may cause and worsen pelvic organ prolapse, but data are inconsistent. Both intra-abdominal pressure associated with exercise and PFM strength vary between activities and between women; thus the threshold for optimal or negative effects on the pelvic floor almost certainly differs from person to person. Our review highlights many knowledge gaps that need to be understood to understand the full effects of strenuous and non-strenuous activities on pelvic floor health.

High level rhythmic gymnasts and urinary incontinence: Prevalence, risk factors, and influence on performance

Urinary incontinence (UI) is common among exercising women, but no studies have been found in rhythmic gymnasts. The aims of the present study were to investigate the prevalence and risk factors for UI in rhythmic gymnasts and the impact of UI on performance. This was a cross‐sectional study including all rhythmic gymnasts competing at the highest national and international level in Norway. One hundred and thirty‐three gymnasts from 22 sports clubs were invited to participate. Background data and possible risk factors were collected via electronic questionnaires. UI was assessed by Urinary Incontinence short form (ICIQ‐UI SF). The "Triad‐specific self‐report questionnaire" was applied to assess the female athlete triad. Joint mobility was assessed by Beighton score. Logistic regression analysis was used to assess possible risk factors. One hundred and seven nulliparous rhythmic gymnasts (80.5% response rate) from 21 sports clubs, with mean age of 14.5 (SD 1.6) years, participated in the study. Thirty‐four (31.8%) reported UI with 21 (61.8%), 3 (8.8%), 6 (17.6%), and 4 (11.8%) reporting stress, urgency, mixed urinary incontinence, and leakage for no obvious reason, respectively. BMI, hypermobility, menarche, disordered eating, and hours of training were not found to be risk factors for stress urinary incontinence. Twenty‐four gymnasts with UI (70.6%) reported incontinence to influence sports performance; 10 (29.4%) reported to be afraid of visible leakage and 5 (14.7%) that the leakage would happen again. Seventy‐four (69.1%) had never heard about the pelvic floor. In conclusion, UI is common in rhythmic gymnasts and may influence sports performance.

Vaginal weights for pelvic floor training: a multiple participant case report

Activity-related incontinence is a problem for women, many with limited access to specialty clinics and practitioners. Incontinence inhibits participation in health-promoting levels of physical activity. Vaginal weights are a treatment option available without a prescription for home use that may help some of these women. This multiple baseline across-participant case study investigated the use of weights in a 'hands-off' pelvic floor exercise program for pre-menopausal women. Three of four participants improved, but did not cure, their incontinence with use of the weights. A fourth participant was unable to successfully use the weights. Referral to a women's health physical therapist was suggested for her. Poor adherence was noted at follow-up in two of three participants, with the one who maintained practice demonstrating continued improvement and increased physical activity. Weights provide a low-cost exercise adjunct to women interested in a flexible and independent incontinence management program. For continued improvement, behavioral factors promoting adherence should also be addressed. Weights are one of the options for women wanting a low-cost solution for activity-related urinary leakage. Problems using the weights or failure to benefit from their use may be indicators of a need for more advanced evaluation by women's health specialists.
