| Abstract |
Purpose: The purpose of this study is to examine the effects of trunk stabilization training on pulmonary functions and
respiratory muscle activity. Methods: All participants in this study were healthy and participated voluntarily. The
participants were divided into 2 groups (10 people in the control group and 10 people in the trunk stabilization training
group). The experimental group had trunk stabilization training with breathing exercises and the control group performed
breathing exercises for 4 weeks. Pulmonary functions were assessed. Digital spirometry (Pony FX, COSMED Inc., Italy) and
free EMG (Apsun, Inc., Italy) were used in order to determine the changes in the respiratory muscle. The SPSSWIN
(version 21.0) package program was used for the statistical analysis. Results: The trunk stabilization training group
(p<.05) had a significant difference in the forced expiratory volume in 1 second, forced vital capacity, inspiratory reserve
volume, inspiratory capacity, and maximal voluntary ventilation prior to and after exercises. The control group, however,
showed no change. No significant difference was seen in the change in respiratory muscular activity between the two
groups. Conclusion: In order to improve pulmonary functions, application of trunk stabilization training can be a
particularly effective intervention method. |
