Effects of Innovative Aerobic Exercise Training in Cystic Fibrosis

This study is a randomized control trial that compares MCT to HIIT using a patient-centered and home-based delivery model with CF Care Centers in the United States. Participants will be randomly allocated to either an MCT or HIIT arm. Both the MCT and HIIT interventions are accepted forms of prescribed exercise in clinical practice. The interventions will be delivered with a telehealth platform using internet (HIPAA-Compliant video), phone, and email/text support. All study sites will receive initial and on-going training and program facilitation to assure consistency of delivering the intervention. All participants across both arms visit their respective CF clinics on a regular basis for routine CF care. Thus, our research team will be able to coordinate all testing/assessment visits, including long-term (18-month timepoint), with participants throughout the study. The primary and secondary outcomes include important patient-centered outcomes as selected by our study's CF Patient and Stakeholder Advisory Board.
