Trampoline effects on pelvic support and urine leakage
Official title: Does a 10-minute Trampoline Protocol Induce Urine Leakage or Changes in Pelvic Morphometry Among Females Who Report That They do Not Experience Symptoms of Urinary Incontinence?
Run by University of Ottawa · NCT07183800 · Data updated 2026-11-12
This study will try a 10-minute high-intensity trampoline session to see if it causes urine leakage or short-term changes in pelvic floor structure in active women aged 18–40 who do not usually leak.

Is this trial a fit for you?
✓Likely a good fit
Physically active females aged 18–40 who rarely experience urine leakage (no more than once per month during exertion), are not pregnant or recently postpartum, and can safely complete a 10-minute trampoline protocol.
✕Probably not a fit
People outside the age range, those with frequent or established urinary incontinence, recent pregnancy, prior pelvic surgery, significant cardiopulmonary or neurological conditions, or inability to jump are unlikely to benefit from this protocol.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
Researchers will enroll physically active females aged 18–40 with no frequent urinary leakage and perform a single laboratory visit with transperineal ultrasound imaging before jumping, immediately after a 10-minute trampoline protocol, and 30 minutes later. Within-subject comparisons will be used to measure changes in bladder neck position, levator plate length, and posterior urethrovesical angle (PUVA). Urinary leakage during the jumping protocol will be monitored and recorded alongside the imaging. The design focuses on acute, real-time mechanical effects of high-impact exercise in asymptomatic participants.
Why it matters
Potential benefit: If successful, the findings could reveal early mechanical changes from high-impact exercise that inform prevention, guidance, and education for young active women.
How similar studies have gone: Prior research links high-impact exercise to higher prevalence of urinary leakage, but real-time ultrasound studies of acute pelvic morphological changes during jumping are limited and this approach is relatively novel.
