Trampoline-Induced Changes in Pelvic Structure and Continence
Sponsor: University of Ottawa
Summary
The goal of this clinical trial is to evaluate whether a short bout of high-intensity trampoline jumping induces urinary leakage or measurable changes in pelvic floor morphology in active females aged 18-40 who do not report symptoms of urinary incontinence. The main questions it aims to answer are: Hypothesis 1: Does a single 10-minute trampoline protocol result in acute changes in pelvic floor structure, including bladder neck position, levator plate length, and/or posterior urethrovesical angle (PUVA)? Hypothesis 2: Do participants report any urinary leakage during the jumping protocol, despite being asymptomatic at baseline? Hypothesis 3: Do pelvic morphology changes recover within 30 minutes post-jumping, or do alterations persist? Researchers will perform within-subject comparisons at multiple time points (pre-jump, immediately post-jump, and 30 minutes post-jump) using transperineal ultrasound imaging to assess structural changes. Participants will: * Attend one laboratory visit * Complete baseline pelvic health questionnaires (ICIQ-UI Short Form and PFD Sentinel). * Undergo 2D transperineal ultrasound imaging in the standing position at rest, immediately post-jumping, and 30 minutes post-jumping. * Perform a 10-minute high-intensity jumping protocol on a mini-trampoline, while heart rate and perceived exertion are monitored. * Verbally report any urine leakage during jumping using standardized descriptors.

Interventions
Water
Participants will undergo a standardized 10-minute high-intensity trampoline jumping protocol designed to elicit mechanical loading on the pelvic floor. Prior to the jumping session, bladder volume will be assessed via transabdominal ultrasound. If a participant's bladder contains less than 100 mL of urine, they will be asked to drink water and wait until a target range of 100-200 mL is reached to ensure consistent pre-jump bladder filling across participants. This approach minimizes variability in bladder volume, which could influence pelvic floor measurements.
