Athletes are almost 3 times more at risk of experiencing urinary incontinence (UI) than sedentary women, with prevalence rates varying from 10.9% in low-impact sports such as cycling to 80% when engaging in high-impact sports such as trampoline gymnastics. To treat UI, pelvic floor muscle (PFM) training (PFMT) is recommended as a first line of treatment.
Objective:
The aim of the present study was to perform a meta-analysis of the available literature on the efficacy of PFMT interventions in young, nulliparous female athletes.
Data Sources:
A literature research was conducted using PubMed, Sport Discus, and Web of Science.
Study Selection:
The inclusion criteria were studies with PFMT intervention in female athletes or recreationally active women. Interventions could be carried out for treatment or prevention of pelvic floor dysfunctions.
Study Design:
Systematic review with meta-analysis.
Level of Evidence:
Level 5.
Data Extraction:
A descriptive analysis of the articles included in the systematic review was carried out. Meta-analyses could be performed on 6 of the included articles, evaluating the maximal voluntary contraction (MVC) of the PFMs, the amount of urinary leakage (AUL), and the vaginal resting pressure (VRP). Random-effects model and standardized mean differences (SMD) ± 95% CI were reported.
Results:
The meta-analysis showed that PFMT produced a significant increase in MVC (SMD, 0.60; 95% CI, 0.11 to 1.08; P = 0.02) and a significant reduction of AUL (SMD, -1.13; 95% CI, -1.84 to -0.41; P < 0.01) in female athletes. No effects were shown in VRP (SMD, -0.05; 95% CI, -1.27 to 1.17; P = 0.93).
Conclusion:
PFMT is shown to be effective in increasing PFM strength and reducing urine leakage in female athletes, being a powerful tool to prevent and treat pelvic floor dysfunction in this population.
