Comparing Heart and Lung Responses to the 6-Minute Stepper Test in Adults with Bronchiectasis and Healthy Adults

What this Trial Is About

This research aims to compare the cardiopulmonary responses to the 6-minute stepper test between individuals with bronchiectasis and healthy controls. Bronchiectasis patients often experience a productive cough, recurrent lung infections, reduced exercise capacity, and decreased muscle strength. The study also investigates how the 6-minute stepper test relates to other exercise tests such as the 6-minute walk test and the 1-minute sit-to-stand test in these individuals. Participants will undergo exercise tests including the 6-minute stepper test, 6-minute walk test, and 1-minute sit-to-stand test. These tests assess their exercise capacity and cardiopulmonary responses. The study is observational and involves no intervention. Measures such as maximal inspiratory and expiratory pressures and peripheral muscle strength will be recorded on the first day. During the study, participants will be evaluated through various assessments including muscle strength tests, cardiopulmonary monitoring before and after exercise tests, and completion of the exercise tests themselves. Secondary measures like lung function, dyspnea, and comorbidity indexes will also be collected. The study involves healthy volunteers and bronchiectasis patients aged 18 and older, with the total participation timeline based on the initial assessment day.
