The effects of expiratory muscle strength training on non-speech and speech tasks

  • Author(s) / Creator(s)
  • The purpose of this study was to determine the effects of an intensive expiratory muscle strength training (EMST) program on the respiratory system. Specifically, lung volume events, chest wall muscle activation patterns and expiratory pressures were measured before and after treatment. The participant involved in this study was a healthy female, 26 years old. The participant completed a set of non-speech and speech tasks before and after EMST. Chest wall kinematics were used to measure lung volume events, surface EMGs were used to measure rib cage and abdominal muscle activity and an expiratory threshold loading device was used to measure changes in expiratory pressure. Results from training indicated positive respiratory and muscle activation changes not only for the treatment target (i.e., expiratory pressure) but for non-treatment targets (i.e., vital capacity, maximum duration phonation, speech, and maximum expiratory pressure generation). These preliminary results have implications for use of an accessible training program geared to maintaining respiratory function for both non-speech and speech activities in healthy older adults.
