Asthma is a chronic respiratory disease that can negatively affect exercise tolerance and functional capacity due to airway inflammation, variable airflow limitation, and symptom-related activity avoidance. Reduced physical activity levels and exercise-induced symptoms often lead to physical deconditioning, which may further impair cardiorespiratory fitness and daily functional performance in individuals with asthma. There is substantial evidence supporting the use of cardiopulmonary exercise testing (CPET) for the evaluation of exercise capacity in patients with respiratory diseases. However, it is not known whether the use of the 6-minute stepper test (6-MST) is a valid and reliable test for the assessment of functional exercise capacity in patients with asthma. The aim of this study is to investigate the reliability and validity of the 6-MST for evaluating functional exercise capacity in individuals with asthma.
