Abstract

Background : This study is for respiratory muscle activity and chest expansion through practice abdominal breathing exercises. Methods : The subjects were consisted normal 30 persons(15 males and 15 females). The control group to 15 people to compare group and 15 people for the abdominal breathing exercise group through lip retraction movement of the therapist with the resistance of mediated abdominal breathing exercises. For 8 weeks EMG was used to know the changes in respiratory muscle. We also found out the changes in chest expansion. And the t-test was conducted to analyze among the compared group, the abdominal breathing group the differences between before and after the experiment. Results : On the changes in respiratory muscle muscular activity in the transverse abdominis have shown significant results(p<.05), and the change in chest expansion was no significant(p>.05). Conclusion : Various breathing exercises in future research on intervention programs can be studied to promote the public if the functional status is considered to be of much help.
