Study Summary

Background: People who are recovering from COVID-19 may continue to have problems that affect their daily life. For instance, they might feel overly tired. Researchers want to learn if exercise can help people recover after COVID-19 infection. Objective: To study if participation in a rehabilitation exercise program can help people recovering from COVID-19. Eligibility: Adults ages 18-80 with a lab-confirmed SARS-CoV2 infection (the virus that causes COVID-19), and are still having some symptoms. Design: Participants will have a medical history and physical exam. They will give blood and urine samples. They will have tests to measure heart and lung function. Their blood vessels will be assessed. Participants will have a computed tomography scan of the body. They will have an ultrasound of the muscles in their arms, legs, and chest. Participants will take a 6-minute walk test. They will take other balance and movement tests. Participants will walk on a treadmill while hooked up to a monitor. Then they will be interviewed. It will be audio-recorded. Participants will complete surveys about their symptoms and daily activities. Participants will take a smell test. For this, they will identify different smells. They will also have memory, attention, and mental functioning tests. Participants will wear an activity monitor on their wrist 24 hours a day. They will exercise 3 times a week for 10 weeks by moving vigorously on a track or treadmill for 30 minutes. They will attend education classes once a week for 10 weeks. Participants will be contacted by phone or email every 3 months for 1 year after they complete the exercise part of the study. They will wear an activity monitor for up to 2 weeks.

Primary Outcome

The 6-minute walk test (6MWT) is a measure of physical capacity and subjects are instructed to walk as far as possible around a pre-measured walking course over a time period of six minutes. The 6-minute walk test distance (6MWD) is the total distance walked in meters during the 6MWT and greater distance walked means better physical capacity. This outcome is reported as the difference between time-points (post- minus pre-10 weeks).
