Effect of Inspiratory Muscle Training on Exercise Tolerance in Asthmatic Individuals

“The aim of this study was to determine the effects of inspiratory muscle training (IMT) on exercise tolerance, inspiratory muscle fatigue, and the perception of dyspnea in asthmatic individuals.”

Conclusion:

“This study has shown that 6 wk of IMT in individuals with mild to moderate asthma significantly increased inspiratory muscle strength, reduced inspiratory muscle fatigue, improved exercise tolerance, and reduced the perception of dyspnea during cycling exercise at È70% V ̇O2max to the limit of tolerance. These data suggest that IMT may be a helpful adjunct to asthma management and has the potential to improve participation and adherence to exercise training in this group. However, it should also be noted that the perception of breathlessness is also an important signal of bronchoconstriction, and thus, caution should be exercised if this symptom is abnormally low.”
