Abstract

|
INTRODUCTION: The purpose of this study was to examine the effects of the respiratory muscle exercises on change of peak expiratory flow and the respiratory muscle strength according to respiratory muscle exercises and to provide evidence for performance enhancement in respiratory failure and prevention.
METHOD: Twenty young healthy men for this study (10 men each in smoker and non-smoker group) and all they were over 20 years old with communicating and exercising independently. They performed respiratory muscle exercises 3 times a week for eight weeks. Peak flow meter was used for measuring peak expiratory flow, Backmuscle dynamometer was used for measuring Respiratory muscle strength . All data were analyzed by t-test, ANCOVA using SPSSWIN 18.0. P-values of <0.05 were considered significant.
RESULT: In the case of smoking group , there were significant differences , from peak expiratory flow and Back-muscle strength between the before and the after of respiratory muscle strength exercises. In the case of nonsmoking group , there were significant differences , from peak expiratory flow and Back-muscle strength between the before and the after of respiratory muscle strength exercises.
CONCLUSION: Respiratory muscle strength exercises improved peak expiratory flow and respiratory muscle strength. These results might be a application in respiratory prevention and enhancement.
