Urinary Incontinence in Competitive Women Powerlifters: A Cross-Sectional Survey

Athletes' Knowledge of Pelvic Floor Dysfunction and Their Knowledge of and Engagement with Pelvic Floor Muscle Training: A Scoping Review

INTRODUCTION

Pelvic floor dysfunction (PFD) is prevalent among athletes. Investigating whether athletes are practicing pelvic floor muscle training (PFMT) will assist in delineating the factors underlying the burden of PFD in this population. Additionally, investigating athletes' knowledge of PFD and knowledge of and attitudes toward PFMT may inform interventions to improve the practice of PFMT.

AIMS

This scoping review aimed to collate the available evidence regarding athletes' knowledge of PFD and their knowledge of and engagement with PFMT. Furthermore, this review aimed to determine the types of athletes (sports and competition levels) research had been conducted on and the definitions of PFD and PFMT most used.

METHODS

Six databases were searched up to January 2024. No study design or publication types were restricted; however, non-English articles were excluded due to resource constraints. Additional publications were identified through the reference lists of included articles. Data were synthesized and presented under subheadings relevant to the aims of this review.

RESULTS

Thirty-five publications were included for data extraction. Athletes had low practice of PFMT, poor knowledge of PFD and PFMT, but positive attitudes toward PFMT. One publication reported that higher levels of knowledge were associated with a lower prevalence of PFD. The athletic population was heterogeneous in sport type and competition level, and the definitions of PFD and PFMT were ill-defined.

CONCLUSIONS

Athletes have a low practice of PFMT and poor knowledge of PFD and PFMT. The education of athletes may have a role in supporting pelvic floor health.

Pelvic Floor Muscle Training on Stress Urinary Incontinence in Power- and Weightlifters: a Pilot Study

INTRODUCTION AND HYPOTHESIS

Stress urinary incontinence (SUI) is defined as involuntary leakage of urine on physical effort and is prevalent among power- and weightlifters. However, there is scant knowledge on treatment options for this population. The aim of this pilot study was to evaluate the potential outcomes and feasibility of a pelvic floor muscle training (PFMT) program on SUI in nulliparous female power- and weightlifters.

METHODS

This was a case-series study, including one weightlifter and two powerlifters aged 21-32 years. The participants conducted 12 weeks of PFMT at home, with weekly follow-up by a physiotherapist. Change in total score of the International Consensus of Incontinence Questionnaire Urinary Incontinence Short Form (ICIQ-UI-SF) was the primary outcome. Secondary outcome was perceived change assessed by the Patient Global Impression of Improvement (PGI-I) Scale and impact on sport participation. PFM strength, endurance, and resting pressure was measured using vaginal manometry. Feasibility was evaluated as adherence to training and self-efficacy (Self Efficacy Scale for Practicing Pelvic Floor Exercises).

RESULTS

One athlete reduced their ICIQ-UI-SF score and experienced improvement in symptoms. One athlete reported no change, and one reported a worsening of symptoms. All three participants improved PFM strength and endurance, completed the testing, and 12 weeks of PFMT, but adherence varied between 40 and 80%. Participants reported a lack of time and energy and forgetting to perform the exercises, as reasons for low adherence.

CONCLUSION

There were varying effects of a 12-week PFMT program on SUI in three strength athletes. The results can create the basis for a future randomized controlled trial.

Acute Effect of Heavy Weightlifting on the Pelvic Floor Muscles in Strength-Trained Women: An Experimental Crossover Study

INTRODUCTION/PURPOSE

Heavy lifting may produce strain on the pelvic floor muscles (PFM) due to high increases in intra-abdominal pressure, but knowledge of the impact of weightlifting on the PFM is lacking. Therefore, this study aimed to investigate acute effects of heavy weightlifting on the PFM in strength-trained women and whether general strength in whole-body exercises correlated to PFM strength.

METHODS

Forty-seven nulliparous women between 18 and 35 yr who regularly performed weightlifting and were able to lift their own body weight × 1.2 in back squat and 1.5 in deadlift were included in this experimental crossover study. They participated in baseline evaluations (questionnaire/measurements of background characteristics and pelvic floor disorders, one-repetition maximum (1RM) tests in back squat and deadlift) and one test day where they were randomized to start with 60 min of weightlifting (four sets of four repetitions at 75%-85% of 1RM in back squat and deadlift) or seated rest of 60 min. Vaginal pressure measurements of PFM resting pressure, strength, and endurance and surface electromyography measurements of PFM resting activity were performed before/after weightlifting and rest.

RESULTS

No statistically significant differences were found when comparing the change in PFM resting pressure, strength, endurance, and resting activity after heavy weightlifting and rest. There were no statistically significant correlations between PFM strength and maximum (1RM) or relative strength (1RM/bodyweight) in either back squat or deadlift.

CONCLUSIONS

Our results imply that heavy weightlifting is well tolerated by the PFM in short term among young, nulliparous, and strength-trained women. Strength in whole-body exercises was not correlated to PFM strength.

Prevalence and Normalization of Stress Urinary Incontinence in Female Strength Athletes

ABSTRACT

Mahoney, K, Heidel, RE, and Olewinski, L. Prevalence and normalization of stress urinary incontinence in female strength athletes. J Strength Cond Res 37(9): 1877-1881, 2023-Strength training is increasing in popularity in women but is also a potential risk factor for stress urinary incontinence (SUI). There is potential for normalization of SUI in sports with high rates of SUI. Pelvic floor physical therapy is an effective treatment for SUI in both athletes and nonathletes, but female strength athletes may not be aware of this option. Our study sought to assess prevalence, normalization, rates of treatment, and preferred sources of information about SUI in female strength athletes. A novel cross-sectional survey was distributed online through social media groups dedicated to female strength athletes with 425 women responding within 4 days. Statistical significance of results was assumed at a 2-sided alpha value of 0.05. 43.5% of athletes experienced incontinence with daily tasks, 59.1% experienced incontinence with normal strength training, and 50.2% experienced incontinence during competition. Of the athletes who experienced incontinence, 61.4% did not have incontinence before starting their sport and only 9.4% had ever sought treatment. 67.9% of all athletes surveyed believed that urinary incontinence was a normal part of their sport. Our findings indicate that SUI is common in female strength athletes and may be a consequence of the sport itself. Normalization of SUI is common, and few athletes seek treatment.

Sports Medicine and the Pelvic Floor

ABSTRACT

The female athlete is seen as a specialist population meaning female considerations, such as pelvic floor dysfunction, are not widely taught within sports medicine. Females have unique anatomical characteristics compared with males including a wider pelvic diameter and an additional orifice in the form of the vagina. Furthermore, symptoms of pelvic floor dysfunction are prevalent among female athletes and transitional periods in their lifespan. They also are a barrier to training and performance. Therefore, it is essential that sports medicine practitioners understand how to identify and manage pelvic floor dysfunction. This report aims to describe the anatomy and function of the pelvic floor, outline the types and rates of pelvic floor dysfunction, discuss evidence-based management, and raise awareness of perinatal bodily changes. Practical recommendations are made to aid sports organizations and sports medicine practitioners in supporting the female athlete and in using a proactive approach to manage the perinatal athlete.

A national survey of urinary incontinence in professional Team England female athletes

OBJECTIVES

To investigate the prevalence of urinary incontinence in Team England female athletes participating in the 2018 Commonwealth Games, the self-imposed lifestyle modifications used to manage symptoms in training and competition and the impact on performance.

STUDY DESIGN

This was a Cross-Sectional Survey. All Team England female athletes participating in 2018 Commonwealth Games were asked to complete a structured questionnaire regarding symptoms and management of urinary incontinence. Chi-squared statistical analysis was applied to relevant data.

RESULTS

103 athletes were included. 52 % reported experiencing urinary incontinence (38 % in training vs 27 % in competition X² = 2.68, p0.13). Highest rates of incontinence were seen in cycling and gymnastics, with lowest rates of incontinence in swimming and rugby. In sports requiring form fitting garments, 64 % did not feel they could wear a pad in training, compared with 19 % in sports with less form-fitting clothing. In competition, 75 % of athletes wearing form-fitting clothing did not feel they could wear a pad, compared with 24 % of those with less form-fitting attire (X² = 16.9, p < 0.001 in training; X² = 24.04, p = <0.001 in competition). 11 % of athletes reported reducing fluid intake to reduce urinary incontinence in training and 8 % reported doing this in competition. Only 3 % of athletes reported that their performance is affected by urinary incontinence.

CONCLUSION

Prevalence of urinary incontinence is higher in athletes than in the general population. Tight-fitting sportswear is a barrier to athletes using pads to manage urinary incontinence. Athletes may reduce fluid intake to reduce urinary leakage in training and competition, which may affect performance. However, few athletes report that urinary incontinence has an impact overall.

Impact of heavy resistance training on pregnancy and postpartum health outcomes

INTRODUCTION AND HYPOTHESIS

Participation in Olympic weightlifting, the Valsalva maneuver, and acute or prolonged supine weightlifting during pregnancy are cautioned against; however, these recommendations are based on expert opinions as opposed to empirical evidence. The aim of this study was to examine the training and health outcomes of individuals who engaged in heavy resistance training during pregnancy.

METHODS

A total of 679 individuals who lifted at least 80% one-repetition maximum during pregnancy participated in an online survey.

RESULTS

Participants were primarily recreational athletes (88%, 332 out of 675) engaged in CrossFit™ (61%, 410 out of 675) and/or weightlifting (49%, 332 out of 675) during pregnancy. Most participants reported no complications during pregnancy or delivery (66%, 388 out of 589), whereas 57% (241 out of 426) reported urinary incontinence following pregnancy. Participants who maintained pre-pregnancy training levels until delivery reported significantly less reproductive complications than those who ceased training levels prior to delivery (p = 0.006). Most respondents engaged in Olympic lifting (72%, 311 out of 432) and lifting in a supine position (71%, 306 out of 437), whereas fewer reported use of the Valsalva maneuver during pregnancy (34%, 142 out of 412). Most returned to weightlifting following delivery (89%, 400 out of 447, average: 3.2 ± 3.0 months), including Olympic lifting (81%, 300 out of 372, average: 4.0 ± 3.4 months) and Valsalva (62%, 213 out of 341, average: 4.5 ± 3.6 months).

CONCLUSIONS

Individuals who engaged in heavy prenatal resistance training had typical perinatal and pelvic floor health outcomes that were not altered whether they engaged in, or avoided Olympic lifting, Valsalva or supine weightlifting.

Urinary Incontinence in Elite Female Athletes

PURPOSE OF REVIEW

To summarize the current understanding on the epidemiology, pathophysiology, and management strategies of urinary incontinence (UI) in female athletes, highlighting findings specific to nulliparous elite athletes.

RECENT FINDINGS

UI occurs in about 20-50% of female athletes of all ages and parity status, around 40% for younger nulliparous athletes, and is more prevalent in high-impact sports. Possible contributing factors to UI in female elite athletes include pelvic floor laxity and bladder neck descent, pelvic floor muscle fatigue, low energy availability, and hypermobility syndrome. In female elite athletes, urinary symptoms negatively affect quality of life, although the effects of symptoms on exercise participation are not well understood. Current management strategies are primarily conservative and centered on behavioral modifications and pelvic floor muscle physiotherapy. UI in female elite athletes appears to be multifactorial. Clarifying how individual factors influence UI in this population will inform athlete counseling, prevention, and treatment strategies.

Does a Kegel Exercise Program Prior to Resistance Training Reduce the Risk of Stress Urinary Incontinence?

This comparative pre-post intervention study investigated the feasibility and benefits of Kegel exercises amongst incontinent women, prior to commencing resistance training (RT), to reduce the risk of stress urinary incontinence (SUI) compared to a group of women without prior Kegel exercises (KE). Incontinence severity index (ISI) score, pelvic floor muscle strength (PFMS), and body composition (such as body mass index (BMI), fat, and muscle mass), were obtained pre and post intervention. Results demonstrated that RT reduced SUI to a significantly greater extent only if preceded by KE as was observed in the Kegel exercise plus RT group (KE + RT) over time. The improvements in total ISI in both the KE + RT and RT groups were large (d = 1.50 and d = 1.17 respectively). A two-way ANOVA indicated a statistically significant improvement in average PFMS within the KE + RT group over time and between the two groups. A positive correlation was found between the average strength of pelvic floor muscles and SUI. Participants in KE + RT group demonstrated a significant increase in muscle mass (p ≤ 0.001) and concomitant reduction in fat mass (p = 0.018). This study determined a dedicated program of KE preceding a RT program improved average pelvic floor muscle strength and was effective in reducing SUI among incontinent women.

Sport-related risk factors for moderate or severe urinary incontinence in master female weightlifters: A cross-sectional study

BACKGROUND

Urinary incontinence (UI), defined as the involuntary loss of urine, is a common, multifactorial condition. It is unclear whether physical activities, their intensity or frequency, may affect the potential for UI in addition to known risk factors in the general population. Higher prevalence of UI has been observed when engaging in high-impact sports, but research is sparse regarding UI in strength sports. Since the Olympic-style weightlifting has seen an unprecedented increase in women's participation in recent years, this study provides much-needed data to investigate whether weightlifting predisposes women to UI.

OBJECTIVES

The aim was to conduct a survey of female Master athletes in countries that are members of the International Weightlifting Federation using a validated incontinence severity index and to study (1) whether known risk factors in the general population increase the odds of UI in female competitive weightlifters and (2) whether sport-related factors are associated with UI after adjusting for known risk factors. The outcomes of interest were moderate or more severe UI and incontinence during lifts specific to weightlifting competitions.

RESULTS

Respondents consisted of 824 female competitive weightlifters from 29 countries, ages 30 to 79, median 41 years. Prevalence of moderate or more severe incontinence was 32%. Higher BMI, prior pregnancies, and depressive mood increased the odds, but age was not associated. Athletes who had engaged in high-impact sports prior to starting weightlifting training were at a higher risk of UI, but participation in prior strength sports was not associated with UI. The predictive probability of moderate or more severe UI increased with more hours per week of weightlifting training.

CONCLUSIONS

Our findings indicate that while female weightlifters had a higher prevalence of moderate or severe UI than in a general population according to the National Health and Nutrition Examination Survey, and that athletes who had engaged in high-impact sports prior to starting weightlifting were at a higher risk of UI.

Elite female athletes' experiences of symptoms of pelvic floor dysfunction: A systematic review

INTRODUCTION AND AIMS

Pelvic floor dysfunction (PFD) is a collection of signs, symptoms and conditions affecting the pelvic floor and urinary incontinence (UI) is the most common type of PFD. Recent systematic reviews have indicated a higher prevalence of UI among female athletes compared to their non-athletic counterparts. To date, no review has been undertaken to investigate female athletes' experiences of PFD. This review aims to offer insight and understanding, through aggregation, summary, synthesis and interpretation of findings from studies that report elite female athletes' experiences of symptoms of PFD.

METHODS

The review protocol was registered in PROSPERO in August 2020. A systematic search was conducted in Embase, MEDLINE (OVID), Cochrane Library, CINAHL, PsycINFO and Web of Science for studies published in the English language reporting elite female athletes' experiences of symptoms of PFD. This review included primary research studies that involved elite female athletes of any age or ethnicity.

RESULTS

Of the 1922 citations retrieved in the search, 32 studies met the methodological criteria for data extraction and analysis. Five main themes emerged: (1) triggers for symptoms of PFD; (2) strategies adopted by athletes to manage/mitigate symptoms of PFD; (3) impact on QOL/daily life; (4) impact on performance; (5) impact on emotions.

CONCLUSIONS

The findings of this review suggest a need to further explore the experiences of PFD among elite female athletes and it is suggested that future research should adopt qualitative methods or incorporate a qualitative component.

Association Between Obstetric History and Urinary Incontinence in a Cohort of Resistance-Trained Women

Purpose

Urinary incontinence has the potential to reduce participation in sport and exercise and diminish athletic performance. The purpose of this study was to explore the association between obstetric history and urinary incontinence in a cohort of resistance-trained women.

Patients and Methods

This international, cross-sectional survey was completed by 1252 women competing in either powerlifting, weightlifting or CrossFit. The Incontinence Severity Index determined the severity of urinary incontinence.

Results

Almost 43% of the participants experienced urinary incontinence in the threemonths prior to the study. The prevalence of urinary incontinence in this cohort according to mode of birth were: caesarean 42.6%, unassisted vaginal 59.3%, vacuum extraction 58.8%, forceps 60.3%, vaginal and caesarean births 66.2%, forceps and vacuum extraction 73.1%. The prevalence of urinary incontinence in the subgroup of women who had undergone urogenital surgery was 63.6%. Kendall’s tau-b indicated that the correlation between ISI score and the number of births was strong and positive (τ = 0.25, p < 0.001).

Conclusion

Our results suggest that both the number of births and mode of birth influenced the likelihood of urinary incontinence in resistance-trained women. Women who had experienced only caesarean births had the lowest likelihood of urinary incontinence, while women who had experienced both vaginal and caesarean births had the most severe and second highest likelihood of urinary incontinence. Women who had undergone urogenital surgery continued to experience a high likelihood of urinary incontinence.

Focus on the Analysis of the Effect of Solving the Nursing Mode on the Time of the Production Time of the First Maternity and the Subjective Happiness of the Postpartum

Objective

Focusing to solve the significance of the nursing mode for preliminary maternity care.

Methods

Selected 116 first mothers produced in our hospital from January 2010 to January 2022, which were divided into the control group and research group. The two groups each paid conventional care and focused on solving the nursing mode care. Analyze the two groups of pregnancy endings, self-efficacy, negative emotions, subjective happiness, and analgesics.

Results

The vaginal delivery rate of the research group was higher than that of the control group, and the cesarean section rate, hospitalization time, and delivery process were lower than the control group (P < 0.05); the amount of bleeding in the postpartum groups increased, but compared with the control group, the increase in bleeding in the research group was smaller (P < 0.05); the research group objective, subjective support, self-evaluation, and subjective happiness index were higher than the control group (P < 0.05).

Conclusion

Focusing to solve the nursing model can help the maternal tension relief, the maternal can quickly enter the role, and it plays an important role in establishing a good nursing relationship.
