Who this trial is looking for
This trial is looking for active women aged 18-40 who do not have urinary leakage issues. Participants will jump on a mini-trampoline for 10 minutes while their pelvic health is assessed before and after jumping.
Are You a Good Fit for This Trial?
You may be able to join if
I am aged 18-40
I engage in regular physical activity or sport
I do not experience frequent urinary leakage
I can complete a 10-minute jumping protocol
You may not be able to join if
I am currently pregnant or have been pregnant in the past 6 months
I have cardiac, pulmonary, metabolic, or neurological conditions
I have a lower body injury that limits my ability to jump
I have had a hysterectomy or incontinence surgery

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.
