”’We examined the changes induced by 3 weeks of IMT in mild / moderate asthmatics. The data are consistent with those of Weiner et al (1992) and confirm their hypothesis that improvements in MIP (maximum inspiratory pressure) and lung function translate into a reduction in exertional dyspnoea.
In addition, the data suggests that where appropriate regimes are used, these changes are observed within 3 weeks of commencement of IMT and lead to an increase in patient’s motivation to take exercise.”
