Purpose: This study aimed to investigate the effects of diaphragmatic breathing training with visual feedback on diaphragm movement and lung function in healthy women.
Methods: A randomized controlled trial was conducted with the participation of 20 healthy college-aged women without any underlying physical conditions. The participants were randomly assigned into two groups: the intervention group that received diaphragmatic breathing training with visual feedback and the control group that underwent sham training without visual feedback. Diaphragmatics movement were assessed through respiratory motion analysis, and lung function was measured using spirometry before and after the training period. Data analysis included a paired t-test to compare within-group differences and an independent t-test to compare the effects between the two groups.
Results: In both groups, diaphragmatic movement significantly increased after the intervention (p<.05). In addition, the intervention group that received visual feedback exhibited significant improvements in forced vital capacity (FVC), forced expiratory volume in 1 s (FEV1), and diaphragm movement (p<.05).
However, the control group without visual feedback demonstrated only a significant increase in diaphragm movement (p<.05). Furthermore, the intervention group showed a significantly greater increase in FVC than the control group.
Conclusion: This study reveals that incorporating visual feedback into diaphragmatic breathing training can effectively enhance diaphragmatic movement and improve lung function in healthy women. These findings suggest the potential benefits of visual feedback in optimizing the benefits of diaphragmatic breathing exercises. These results have implications for respiratory rehabilitation, stress reduction, and overall well-being in the general population. More studies are recommended to explore the long-term effects of diaphragmatic breathing training with visual feedback and its application in clinical populations with respiratory disorders.
