Purpose An overactive bladder (OAB) may be defined as urgency that is a sudden, compelling, difficult to defer desire to pass urine that is usually accompanied by frequency and nocturia and possibly by incontinence. Obesity and old age are two factors in various causes of OAB. Several epidemiologic studies have identified positive associations among obesity, old age, urinary incontinence, and OAB. However, although exercise has been known to improve obesity and reduce incontinent urine loss, little research has been done in elderly women. Therefore, we investigated the effects of exercise on obesity-related metabolic factors, blood lipid factors, and OAB symptoms in elderly Korean women. Methods Twenty-one women aged between 69 and 72 years were recruited from the Seoul senior towers in Korea. All subjects worked out on a motorized treadmill and stationary cycle for 40 minutes, respectively, and performed resistance exercise for 30 minutes once a day for 52 weeks. Body composition, blood pressure, blood lipids, OAB symptom score, and King's health questionnaire were investigated and analyzed. Results Before performing physical exercise, all subjects showed increased OAB symptoms in association with enhanced body mass index (BMI), percentage fat, and blood lipid profiles. However, physical exercise for 52 weeks suppressed BMI, percentage fat, and blood lipid profiles and thus improved OAB symptoms. Conclusions We suggest that long-term physical exercise can be a valuable tool for remarkable improvement of OAB.
