Primary Outcome Measures

Name	Time	Method
<br> 1. Inspiratory muscle strength - maximal inspiratory pressure assessed by a digital manovacuometer<br> 2. Inspiratory muscle endurance – time, volume, flow, work and power assessed by an electronic tapered flow resistive loading device<br> 3. Functional capacity – maximal distance covered during shuttle walking test<br> 4. Quality of life - Brazilian version of the Asthma Quality of Life Questionnaire<br><br> Assessed at baseline, 8 weeks and 3 months.<br>

Secondary Outcome Measures

Name	Time	Method
<br> 1. Lung function: Forced expiratory volume in the first second-FEV1, forced vital capacity-FVC and peak expiratory flow-PEF<br> 2. Hospital admissions<br> 3. Number of exacerbations<br><br> Assessed at baseline, 8 weeks and 3 months.<br>
