Trial results for the COVID-19, Chronic Adaptation and Response to Exercise (COVID-CARE) study were posted on ClinicalTrials.gov on 2026-05-12. The study, which enrolled 48 participants, investigated if a rehabilitation exercise program could help people recovering from COVID-19, reporting a mean increase of 57.7 meters in 6-minute walk distance for the aerobic exercise intervention group.
Background
People recovering from COVID-19 may experience persistent problems that affect their daily life, such as prolonged fatigue. Researchers are exploring interventions like exercise to help individuals recover after SARS-CoV2 infection. This study aimed to assess whether participation in a rehabilitation exercise program could aid in the recovery process for those still experiencing symptoms post-COVID-19.
Trial design
This study, designated as Phase NA, enrolled 48 participants to investigate the condition COVID-19. The objective was to study if participation in a rehabilitation exercise program could help people recovering from COVID-19. Participants were adults aged 18-80 with lab-confirmed SARS-CoV2 infection who were still experiencing symptoms. The trial compared an Aerobic Exercise Intervention (AET+) group with a Control Group (CON).
Key results
The trial reported key measurements related to the change in 6-minute Walk Test Distance (6MWD):
- For the Aerobic Exercise Intervention (AET+) group, the mean change was 57.7 meters (Standard Deviation 44.67).
- For the Control Group (CON), the mean change was 18.4 meters (Standard Deviation 25.67).
What this means
The results suggest that a rehabilitation exercise program, specifically an aerobic exercise intervention, may improve functional exercise capacity in individuals recovering from COVID-19. The observed greater increase in 6-minute walk distance in the intervention group compared to the control group indicates a potential benefit for addressing lingering symptoms such as fatigue and reduced physical endurance. While these measurements provide insight into the intervention's effect, the absence of reported statistical analyses means further interpretation regarding significance is limited.
