Effects of Breathing Exercises Using Virtual Reality and Schroth Breathing Exercises on the Lung Function of Adults in Their 20s

Purpose: This study investigated the effect of virtual reality and Schroth breathing exercises on the lung function characteristics of normal adults in their 20s.Methods: The subjects were randomly divided into groups with ten people each in the experimental groups, namely the virtual reality breathing exercise group (BBEG) and the Schroth breathing exercise group (SBEG), and the control group.The experimental groups performed each breathing exercise for 4 weeks.Subsequently, pulmonary function test indicators such as the forced vital capacity (FVC) and the forced expiratory volume (FEV1) were measured.Results: In the within-group comparison of the subjects before and after the exercises, there was a significant difference in the FVC and FEV1 (p< 0.05), but there was no significant difference in FEV1/FVC.The result of the difference test between groups showed that there was a significant difference in FEV1/FVC after exercise (p< 0.05).However, there were no significant differences in the remaining items (p> 0.05).Conclusion: Improvement in lung function was seen in both exercise groups, and the changes in FEV1/FVC indicated significant improvement in the lung function of the experimental groups compared to the control group.
