IMT Improves Lung Function And Reduces Exertional Dyspnoea In Mild/Moderate Asthmatics

“Weiner et al. (1992) have reported improvements in lung function, asthma symptoms and reductions in usage of medication following six months of pressure threshold inspiratory muscle training (IMT). Where interventions require compliance with a programme of training, it is important that patients perceive benefits rapidly if compliance is to be maintained. This study examined the changes induced by 3 weeks of IMT in mild/moderate asthmatics.”

Conclusion:

“Data are consistent with those of Weiner et al. (1992) and confirm their hypothesis that improvements in MIP and lung function translate into a reduction in exertional dyspnoea. In addition, the data suggest that where appropriate training regimens are used, these changes are observed within 3 weeks of commencement of IMT and lead to an increase in patients’ motivation to take exercise.”

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.”

Development And Evaluation Of A Pressure Threshold Inspiratory Muscle Trainer For Use In The Context Of Sports Performance

“Inspiratory muscle training (IMT) became widespread, particularly in a clinical context, and at the time of this research a pressure threshold training device suitable for training the inspiratory muscles of healthy humans did not exist. The purpose of this paper was to document the design and development of such a device – the POWERbreathe.
