Design outcomes

Primary

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