The Efficacy of Pilates on Urinary Incontinence in Korean Women: A Metabolomics Approach.

Pilates has been known as exercise intervention that improves the function of pelvic floor muscle (PFM) associated with impacting urinary incontinence (UI). This study investigated the effect of Pilates on UI in Korean women by determining the change in functional movement of PFM (FMP) and metabolic profiles. UI group with Pilates (UIP, = 13) participated in 8-weeks Oov Pilates program, and 8 subjects were assigned to Control and UI group with no Pilates (UINP), respectively. Before and after 8 weeks, plasma samples were collected from all participants, and ultrasonography was used to measure the functional change of PFM for calculating FMP ratio. Plasma samples were analyzed by mass spectrometry to identify the change of metabolic features. After 8-weeks intervention, FMP ratio was remarkably decreased in UIP (48.1% ↓, < 0.001), but not in Control and UINP ( > 0.05). In metabolic features, L-Glutamine (/: 147.07 [M + H]), L-Cystathionine (/: 240.09 [M + NH]), L-Arginine (/: 197.1 [M + Na]), and L-1-Pyrroline-3-hydroxy-5-carboxylate (/: 147.07 [M + NH]) were significantly elevated solely in UIP ( < 0.001). Our study elucidated that Pilates can ameliorate the FMP and enhance the specific metabolic characteristics, which was potentially associated with invigorated PFM contractility to effectively control the bladder base and continence.
