Abstract

Background: Postnatal women often experience reduced tidal volume due to physiological changes during pregnancy and childbirth, including the weakening of pelvic floor muscles (PFMs). The postnatal period is marked by various physiological and mechanical alterations. These alterations may result in diminished tidal volume, dyspnea, and reduced exercise tolerance, thereby impacting overall quality of life

Purpose: This study investigates the effect of pelvic floor muscle strengthening, specifically through Kegel exercises, on tidal volume in postnatal women.

Methods: A randomized controlled trial was conducted with 100 postnatal women divided into an intervention group (n=50) performing supervised Kegel exercises and a control group (n=50) receiving standard postnatal care. Tidal volume was assessed using spirometry at baseline and after an eight-week intervention.

Results: The intervention group showed a statistically significant improvement in tidal volume (mean increase of 20%, p<0.01) compared to the control group (mean increase of 5%, p=0.12). Conclusion: This study shows that postpartum women's tidal volume is greatly increased by strengthening their pelvic floor muscles, particularly through Kegel exercises. These findings highlight the potential role of PFM exercises in enhancing respiratory function and overall recovery in postnatal women.
