Age: 40 and older, up to 59. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Patients with a COPD GOLD stage 2
• Age 40-59 years
• Maximal Inspiratory Pressure (MIP) value of less than 70 cmH₂O or below the lower limit of normal for their age and gender
• Clinically stable for at least 4 weeks prior to the study
