Abstract
ObjectiveTo explore any effect of high-intensity inspiratory muscle resistance training on exercise capacity and life quality for persons with bronchiectasis.
MethodsSixty patients with bronchiectasis were randomly divided into an observation group and a control group, each of 30. The observation group received two 30-minute sessions of inspiratory muscle resistance training daily using the PowerBreak inspiratory muscle trainer 3 days/week for 8 weeks. The intensity was 70% of the maximum inspiratory pressure (MIP). The control group underwent the same training with the intensity at 10% of the MIP. The severity of illness, pulmonary function, respiratory muscle strength and endurance, exercise capacity and life quality of the two groups were evaluated before and after the intervention.
ResultsCompared with before the intervention, the average MIP in the observation group and the average distance they walked in the 6min walk test (6MWT) improved significantly. Their average social factor score on the Leicester cough questionnaire had increased significantly, while their average heart rate and self-perceived exertion during the 6MWT had decreased significantly. There were no significant differences in any of these indicators for the control group.
ConclusionsHigh-intensity inspiratory muscle resistance training can significantly improve the exercise capacity and life quality of patients with bronchiectasis. The treatment is worthy of further research and application in the clinic.
