The Effect of Interval Exercise on Functional Outcomes in Veterans With COPD and OSA

Description

The term “Overlap Syndrome” (OS) is used to describe the presence of both chronic obstructive pulmonary disease (COPD) and obstructive sleep apnea (OSA) in a single patient. Veterans with OS who also have excessive daytime sleepiness (EDS-OS) are at highest risk for functional decline yet have the greatest barriers to exercise training. Thus, there is a critical need to identify novel exercise strategies that meet the individual needs and capacities of Veterans with EDS-OS. The investigators propose to test moderate intensity interval training (MIIT), a novel exercise intervention whose translation into durable lifestyle change may be facilitated by the feasibility of short bouts of increased PA. The investigators proposal addresses key knowledge gaps in rehabilitation research by investigating the clinical phenotype of EDS-OS to determine the association with functional outcomes and response to a novel exercise intervention with the goal to reduce functional decline.
