title: The impact of the pelvic floor muscles on dynamic ventilation maneuvers.
abstract: [Purpose] The aim of the present study was to examine the impact of the pelvic floor muscles (PFM) on dynamic ventilation maneuvers. [Subjects and Methods] The subjects were 19 healthy female adults in their 20s who consented to participate in the present study. Electromyography (EMG) was used to examine respiratory muscle activity, and a spirometer was used to examine vital capacity before and during contraction of the PFM. [Results] There were statistically significant differences in the sternocleidomastoid (SCM), rectus abdominis (RA), external oblique (EO), transverse abdominis/internal oblique (TrA/IO), and maximal voluntary ventilation (MVV) when the PFM was contracted. [Conclusion] Contraction of the PFM can be effective in promoting activation of the respiratory muscles and vital capacity. Therefore, the PFM should be considered to improve the effects of respiratory activity.
