This randomized controlled trial will evaluate whether a rugby-tailored pelvic floor muscle training programme reduces urinary incontinence symptoms and influences neuromuscular performance in professional and semi-professional women rugby players. A total of 48 players aged 18 to 45 years with self-reported urinary incontinence will be randomly assigned in a 1:1 ratio to the pelvic floor muscle training group or a control group.
The intervention group will complete an individualized, remotely supervised programme integrating pelvic floor muscle contractions, breathing and postural coordination, the "Knack" technique, progressive functional exercises, and rugby-relevant movement tasks. The control group will continue usual rugby training without study pelvic floor muscle training during the intervention period.
Outcomes will be measured at baseline and immediately after the intervention. The primary outcome is change in urinary incontinence severity measured with the International Consultation on Incontinence Questionnaire-Urinary Incontinence Short Form (ICIQ-UI SF). Secondary outcomes include broader pelvic floor symptom screening, jump performance, maximal isometric lower-limb force, reactive strength, and programme adherence.
