Dynamic changes of the pelvic floor in elite athletes of different sports

摘要: Introduction: One of the functions pelvic floor muscles (PFM) is to support organs and continence. This continence mechanism tends change when PFM are exposed high-impact exercises. Objetives: To describe dynamic changes in (PF) elite nulliparous athletes. Methods: Translabial two three-dimensional ultrasound was used assess PF anatomy function athletes (n=8). ultrasonography performed after voiding supine position, using a vaginal probe. The descent assessed on maximum Valsalva maneuver, whilst volume datasets were acquired at rest, during voluntary  contraction (MVC) maneuver. each maneuver least 3 times, with most effective being for evaluation. Results: bladder neck 14 mm javelin thrower, highest value compared remaining participants. Three featured rectocele (swimming, gymnastics throw) 4 participants presented paravaginal defect (volleyball, horsemanship, throw printer). volleyball athlete had levator hiatal area MVC value. Conclusions: present minimal differences evaluated parameters. sample small generalize results, but there tendency exercises have lower CMV value. Further studies needed corroborate these results.
