University of Colorado, Denver·interventional·Posted May 8, 2023·Updated Jan 29, 2026

In Brief

A clinical study evaluating Exercise training for Occupational Exposure. Completed, enrolled 12 participants across 2 sites.

Detailed Summary

Some military personnel who have been exposed to burn pit emissions, desert dust, and other airborne hazards experience new respiratory symptoms after deployment. The goal of this clinical trial is to learn about exercise in veterans with new respiratory symptoms after deployment to Southwest Asia. The main questions it aims to answer are: 1. Do veterans with new respiratory symptoms after deployment have heart or lung abnormalities that contribute to difficulty exercising? 2. Does high-intensity interval training (HIIT) improve fitness and symptoms? Study participants will complete the following: 1. Study Visits 1A and 1B: Exercise test (VO2max test), echocardiogram (heart ultrasound), blood tests, questionnaires 2. Exercise program: 12 weeks of 3x/week supervised HIIT on upright stationary bicycle (\~40 minutes each) and 3x/week home aerobic exercise (45 minutes each) 3. Study Visits 2A and 2B: Exercise test (VO2max test), echocardiogram (heart ultrasound), blood tests, questionnaires
