New exercise trick may help COPD patients get fit without gasping for air

This study tests a new exercise approach for people with COPD, a lung disease that makes breathing hard. Researchers will compare standard pulmonary rehab with a version that uses a blood flow restriction cuff during low-intensity aerobic exercise. The goal is to see if this method reduces inflammation, improves oxygen levels, and boosts exercise capacity better than standard care. The study involves 34 adults aged 40–80 and lasts 8 weeks.
