To determine the submaximal exercise capacity of patients with cystic fibrosis (CF) by means of the 6-minute walk test (6MWT), correlating the results with clinical score, nutritional status, radiographic score, and pulmonary function tests. ⋯ This study showed that most patients attending an adult CF program had reduced submaximal exercise capacity. The 6MWT can be valuable for identifying patients who might experience oxygen desaturation and physical impairment in daily activities.
