Each day more women around the world practice high impact physical activities and this may be a risk factor for urinary incontinence (UI) in young. We verified the prevalence of UI and the impact in quality of life (QoL) in high-performance swimmers, through a cross-sectional observational study with 9 high performance swimmers and 9 sedentary women who responded the International Consultation on incontinence Questionnaire - Short Form (ICIQ-SF), participated in a functional evaluation of pelvic floor muscles with bidigital palpation and pad test. We verifed that was present in 78% of high-performance swimmers, and the quality of life was significantly worse (p =.037) when compared to sedentary women. These findings led us to conclude that presence of UI affects the quality of life, even if it is not a factor of abandonment of the sport.
