Abstract

|
|
Purpose: The purpose of this study is to examine the effects of round shoulder improvement exercise on posture, muscle thickness, and respiratory function in adults with round shoulder posture.
Methods: This study was conducted on 17 participants. These participants were randomly allocated to two groups: Group Ⅰ (n=9) and Group Ⅱ (n=8).
Participants in all groups performed exercises for 30 minutes, with 3 sessions per week for 4 weeks. Combined exercises were performed in group Ⅰ to improve round shoulder posture, while KSPO gymnastics basic was performed in group Ⅱ. Round shoulder posture, muscle thickness, and respiratory functions were assessed in all participants. Wilcoxon test was used in order to determine statistical significance of differences (p<.05) before and after training. The Mann-Whitney test was used to determine the statistical significance of differences between the groups.
Results: The results are as follows. After the intervention, significant effects on the improvement of the muscle thickness of the upper trapezius and diaphragm were observed in group Ⅰ compared to group Ⅱ (p<.05). There was no significantly difference between both the two groups in the round shoulder posture and respiratory functions (p>.05).
Conclusion: Based on the results of this study, it is expected to be effective in changing muscle thickness when performing combined exercises for round shoulder. But it is not effective in round shoulder posture and respiratory function of adults with round shoulder.
