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.",[9],[20],{"facility":21,"status":22,"city":23,"state":24,"zip":25,"country":26,"countryCode":27,"cosmosGeoPoint":28,"geoPoint":33,"contacts":34},"University of Ottawa - Lees Campus","RECRUITING","Ottawa","Ontario","K1S 5S9","Canada","CA",{"type":29,"coordinates":30},"Point",[31,32],-75.69812,45.41117,{"lat":32,"lon":31},[35,41,44],{"name":36,"role":37,"phone":38,"phoneExt":39,"email":40},"Sabine Vesting, PhD","CONTACT","613-562-5800","4102","svesting@uottawa.ca",{"name":42,"role":37,"phone":38,"phoneExt":39,"email":43},"Grace Collins, BSc","gcollins@uottawa.ca",{"name":45,"role":46,"phone":10,"phoneExt":10,"email":10},"Linda McLean, PhD","PRINCIPAL_INVESTIGATOR",{"type":46,"investigatorFullName":48,"investigatorTitle":49,"investigatorAffiliation":5,"oldNameTitle":10,"oldOrganization":10},"Dr. Linda McLean","Full Professor","100607072","trampoline-induced-changes-in-pelvic-structure-and-continence-100607072",false,"NCT07183800","Trampoline-Induced Changes in Pelvic Structure and Continence","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?","TRAM","Inclusion Criteria:\n\n* Aged 18-40\n* Engage in regular physical activity or sport\n* Do not experience frequent urinary leakage (no more than once per month during exercise, coughing, or sneezing)\n* Can complete a 10-minute jumping protocol\n\nExclusion Criteria:\n\n* Currently pregnant or have been pregnant in the past 6 months\n* Have cardiac, pulmonary, metabolic, and\u002For neurological conditions\n* Have a lower body injury that limits your ability to jump\n* Have had a hysterectomy and\u002For incontinence surgery",true,"FEMALE","18 Years","40 Years",{"count":63,"type":64},30,"ESTIMATED","OBSERVATIONAL","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.
