Mahoney, K, Heidel, RE, and Olewinski, L. Prevalence and normalization of stress urinary incontinence in female strength athletes. J Strength Cond Res XX(X): 000-000, 2023-Strength training is increasing in popularity in women but is also a potential risk factor for stress urinary incontinence (SUI). There is potential for normalization of SUI in sports with high rates of SUI. Pelvic floor physical therapy is an effective treatment for SUI in both athletes and nonathletes, but female strength athletes may not be aware of this option...
