Official title
The Duke Healthy Breathing Study Stage 2 (DHBS): A Randomized Controlled Trial Assessing the Safety and Feasibility of Respiratory Muscle Training and Exercise Training in Children and Adolescents With Persistent Asthma
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The purpose of this study is to assess the safety and tolerability of a 6-week Inspiratory Muscle Training and cardiovascular exercise training program in children and adolescents with asthma. To also determine the efficacy of inspiratory muscle training and exercise in increasing respiratory muscle strength and endurance, and to explore relationships between fitness interventions (inspiratory muscle training and exercise), exercise tolerance, airway closure and dyspnea scores.
