Regular exercisers at midpregnancy tend to have stronger pelvic floor muscles than their sedentary counterparts, suggests a cross-sectional study published in the American Journal of Obstetrics and Gynecology. The study compared vaginal resting pressure, pelvic floor muscle strength, and endurance in regular exercisers (exercise ≥30 minutes, 3 or more times per week) and nonexercisers at midpregnancy. It also evaluated whether regular general exercise or pelvic floor muscle strength was associated with urinary incontinence. Regular exercisers had statistically significant stronger and more enduring pelvic floor muscles. Only pelvic floor muscle strength remained statistically significant, when adjusting for possible confounders. Pelvic floor muscle strength, but not regular general exercise, was associated with urinary continence.
