Study Overview
Brief Summary
The improvement in inspiratory muscle function might result in beneficial changes in breathing pattern during whole body exercise. The hypothesis is the effect of inspiratory muscle training as an adjunct to a pulmonary rehabilitation program improves the breathing pattern during an incremental cycle exercise.

Outcomes
Primary Outcomes
Change in breathing pattern during an incremental cycle exercise test
Time Frame: Baseline and 8 weeks follow-up
At comparable levels of ventilation breathing frequency, inspiratory time (Ti), expiratory time (Te), total time of the respiratory cycle (Ttot), inspiratory duty cycle (Ti/Ttot), and inspiratory flow rates will be compared.
Secondary Outcomes
No secondary outcomes reported
