PURPOSE: The purpose of this study was to investigate the immediate effects of inspiratory muscle training on diaphragm movement and pulmonary function in healthy women.
METHODS: The subjects of the study were 27 young women between ages 19 and 22 years who had no history of orthopedic damage for the last 6 months. The 27 participants were randomly selected and spontaneously participated and consented to the purpose of the study. This study measured diaphragm movement and pulmonary function under two different conditions, before and after inspiratory muscle training. Ultrasonography is appropriate for measuring diaphragm movement, and Pony Fx is appropriate to measure pulmonary function such as forced vital capacity (FVC), forced expiratory volume in 1 second (FEV1), FEV1/FVC ratio, and peak expiratory flow (PEF) before and after inspiratory muscle training. Paired t-test with a significant level of .05 was used for statistical analysis.
RESULTS: As a result, diaphragm movement significantly increases 1.45cm from before inspiratory muscle training (p<.05). Also, FVC, FEV1, and FEP significantly increase 11.25%, 6.96%, and 8.18%, respectively, from before inspiratory muscle training (p<.05).
CONCLUSION: The diaphragm movement and pulmonary function of the healthy women in this study were in stantly affected by inspiratory muscle training. From these results, we need to confirm effects of inspiratory muscle training on clinical patients such as pulmonary disease.
