INTRODUCTION: Inspiratory muscle training (IMT) has been used in sports to improve factors that can positively influence sports performance. However, the effects of IMT on athletes with disabilities are less well explored. This study aimed to investigate the effects of IMT on the pulmonary function, respiratory muscle strength, aerobic performance, sports skills, and quality of life (QoL) of wheelchair rugby (WCR) athletes.
METHODS: A pre-post-intervention case series study of IMT was carried out with six WCR athletes. Pulmonary function (spirometry), respiratory muscle strength (manovacuometry), aerobic (cardiopulmonary exercise test) and WCR skills (Beck Battery) performance and QoL (WHOQOL-DIS) were investigated. Participants were submitted to a six-week IMT with a linear load resistor involving 30 dynamic inspiratory maneuvers twice daily for five days/week.
RESULTS: Increases in maximum load (+14.6%; p = 0.03), maximum effort time (+19.4%; p = 0.03), absolute and percent of predicted maximal expiratory muscle pressure (both +13.2%; p = 0.04) and absolute and percent of predicted maximal inspiratory muscle pressure (both +28.6%; p = 0.04) were observed. No significant differences were observed for pulmonary function variables, WCR skills performance or QoL.
CONCLUSION: IMT seemed to be effective at improving the respiratory muscle strength and aerobic performance of WCR players but there was no impact on pulmonary function, sports skills or QoL.
