Interval exercise may improve daily function and heart health for veterans with COPD and sleep apnea

Official title: The Effect of Interval Exercise on Functional Outcomes in Veterans with COPD and OSA

Funded at Salem VA Medical Center · NIH-11446453 · Data updated 2026-11-12

This project tests whether a structured interval exercise program helps veterans with combined COPD and sleep apnea improve daily functioning, activity, and heart health.

Who could benefit from this research

Could help

Veterans diagnosed with overlap syndrome ( COPD and obstructive sleep apnea ) who are capable of participating in an exercise program and providing wearable activity data and blood samples.

Less likely to help

Patients without overlap syndrome or those unable to participate in exercise may not benefit from this study.

What this research studies

Veterans with overlapping COPD and obstructive sleep apnea often experience faster functional decline. The study will monitor functional status using the SF-36, daily step counts, and cardiovascular health markers such as CRF, FMD, and hs-CRP to tailor an exercise strategy. By focusing on 3 key domains—participation in daily life, physical activity, and cardiovascular health—the team aims to design an exercise plan that maintains or improves quality of life for OS patients. The research will also consider how excessive daytime sleepiness relates to functional outcomes within the exercise intervention. The goal is to reduce functional decline through increased physical activity tailored to this complex patient group.

Why it matters

Potential benefit: If successful, veterans with OS could experience better daily functioning and cardiovascular health through a personalized exercise plan.

How similar studies have gone: Previous research supports exercise improving function and cardiovascular markers in COPD and sleep apnea separately; combining them in OS is a newer approach but builds on established benefits.
