Abstract

Purpose : The purpose of this study was to investigate the effects of transverse abdominal muscle contraction on pulmonary function in supine position.
Methods : 10 female and 10 male college students were recruited this study. Pulmonary Function test was measured with
QUARK SPIRO. To check the changes in lung function with transverse abdominal muscle contraction, we tested pulmonary function in the supine, with and without transverse abdominal muscle contraction. While the transverse abdominis was activating, we investigate in the change of forced expiration. All statistical analyses were performed using SPSS Statistics VER.12.0 for window version p-values less than 0.05 were used to identify significant differences. Statistical analysis was used Paired t-test to know difference between activated and non-activated TrA of forced expiration.
Results : The subject with transverse abdominal muscle contraction showed significant increments in variable of FVC, FEV1, PEF compared to the pre-intervention results (p<0.01).
Conclusion : These results indicate that spontaneous contraction of the TrA helps pulmonary function. And the selective
contraction of the transverse abdominis at the end of forced inspiration makes increases in the lung capacity.
