Abstract

[Purpose] This study was conducted to investigate the effect of the correlation between the pelvic floor muscles (PFM) and diaphragmatic motion during breathing. [Subjects] The subjects of this study were 20 healthy female students who listened to an explanation of the study methods, purpose and agreed to participate in the experiment. [Methods] Radiograph equipment was used to examine diaphragmatic motion with contraction of the PFM during breathing, and a spirometer was used to examine lung vital capacity. [Results] The results revealed a significant change in the diaphragmatic motion and pulmonary function (FEV1, MVV). FEV1 and MVV showed significant differences when the PFM was contracted. Diaphragmatic motion showed a significant difference when the PFM was contracted. [Conclusion] Diaphragmatic motion and contraction of the PFM correlate with breathing. In addition, breathing is much more effective during contraction of the PFM. Therefore, PFM strengthening exercises should be included in respiratory rehabilitation programs.
