To evaluate Maximum Voluntary Contraction (MVC) of the Pelvic Floor Muscles (PFM) in sportswomen, to observe the urinary symptoms and their impact on the Quality of Life (QoL).
Observational cross-sectional study.
Gyms and teams in the North of Portugal.
Sportswomen (n = 197).
The measurement was performed using a manometer. The sportswomen were instructed to perform 3 MVC of the perineum, held for 3 s. The Kings Health Questionnaire (KHQ) was used to evaluate urinary symptoms and the QoL of the sportswomen.
Age significantly influenced (p < 0.05) the QoL in all domains. An increase in BMI was also significantly associated with a decrease in the QoL. MVC values had a highly significant effect on the overall QoL and all domains, including a reduction in urinary symptoms. The weekly time of physical activity was associated with a better QoL in symptomatology. The practice of high-impact activities decreased the QoL (compared to low-impact activities). The vaginal resting pressure values ranged from 1.60 to 59.80 (24.34 ± 11.00).
Age, BMI and high-impact sports appear to be the leading factors that promote the onset of SUI, which in turn decrease the QoL in sportswomen. There was a positive association between MVC and weekly time of physical activity in the QoL.
评估运动员盆底肌肉的最大自主收缩（MVC），观察尿失禁症状及其对生活质量（QoL）的影响。
观察性横断面研究。
葡萄牙北部的健身房和运动队。
运动员（n=197）。
使用压力计进行测量。运动员被指示进行 3 次会阴 MVC，每次持续 3 秒。使用 King's 健康问卷（KHQ）评估运动员的尿失禁症状和生活质量。
年龄显著影响（p<0.05）所有领域的生活质量。BMI 的增加也与生活质量的下降显著相关。MVC 值对整体生活质量和所有领域都有显著影响，包括减少尿失禁症状。每周体育活动时间与症状方面的更好生活质量相关。进行高冲击活动会降低生活质量（与低冲击活动相比）。阴道静息压力值范围为 1.60 至 59.80（24.34±11.00）。
年龄、BMI 和高冲击运动似乎是导致压力性尿失禁发生的主要因素，进而降低运动员的生活质量。MVC 与生活质量的每周体育活动时间之间存在正相关关系。
