What the study found

Inspiratory-muscle training improved respiratory-muscle strength and endurance and was associated with changes in intercostal muscle fibres.

Participants and protocol

Fourteen men with severe COPD were randomized to supervised inspiratory training or sham training for five weeks, with muscle biopsies before and after.

What this cannot establish

This is supervised clinical rehabilitation in severe lung disease. The protocol does not establish a healthy athlete's training dose or authorize self-treatment of breathing symptoms.
