Inspiratory Muscles Can Be Trained To Increase Strength Or Endurance

“This study examined whether resistive loading can train the inspiratory muscles differentially.”

Conclusion:

“Results demonstrate that pressure threshold resistive inspiratory muscle training can be utilised to train specifically for improvements in strength or endurance and that the improvements are maintained well post-training.”

Acute Cardiorespiratory Responses To Inspiratory Pressure Threshold Loading

“The purpose of this study was to test the acute responses to differing pressure threshold inspiratory loading intensities in well-trained rowers.“

Conclusion:

“Although all loads elicited a sustained increase in forced capacity, only the 60% load elicited a sustained rise in mean arterial blood pressure, diastolic blood pressure, and systolic blood pressure, providing evidence for a metaboreflex response at this load.”

Specificity And Reversibility Of Inspiratory Muscle Training

“The purpose of this study was to evaluate the pressure-flow specificity of adaptations to inspiratory muscle training (IMT), in addition to the temporal effects of detraining and reduced frequency of training upon these adaptations.”

Conclusion:

“Data supports the notion of pressure-flow specificity of inspiratory muscle training. Detraining resulted in small but significant reductions in inspiratory muscle function. Reducing training frequency by two thirds allowed for the maintenance of inspiratory muscle function up to 18 wk post-IMT.”
