Introduction: Urinary incontinence (UI) is thought of as a problem with aging however, studies demonstrate young, physically fit nulliparous women also experience UI. Factors that contribute to incontinence in this population of women are not well understood. Studies suggest weak connective tissue, high-intensity and high-impact activities, heavy training, and possible pelvic floor muscle (PFM) fatigue. Though RCTs demonstrate benefit of pelvic floor muscle training (PFMT) for SUI, none assess the intervention for nulliparous sports women.

Introduction:  Though pelvic floor m training (PFMT) is effective for treatment of stress urinary incontinence (SUI) (Level I evidence), how this works is not clear. Several theories are presented including (1) PFM morphology is altered; (2) PFMT prevents bladder and urethral descent with activities increasing intra-abdominal pressure; (3) PFMT increases strength of a voluntary pre-PFM contraction and appears to reduce downward movement of bladder neck with cough (ie the Knack) ;  PFMT facilitates unconscious, automatic firing of PFM, increasing maximal urethral closure pressure (MUCP) during increases in intra-abdominal pressure.
