New study aims to find best exercise test for lung disease patients

This observational study compares how people with bronchiectasis and healthy volunteers respond to different exercise tests, including a 6-minute stepper test, a 6-minute walk test, and a 1-minute sit-to-stand test. Researchers will measure breathing, heart rate, and muscle strength to see which test best captures exercise limitations. The goal is to improve how exercise capacity is assessed in bronchiectasis, without testing any new treatment.
