Read our Depressive Disorder, Major research guide →This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
This trial is investigating whether aerobic exercise might help people with major depression by changing their gut bacteria and improving their mood and mental clarity. Researchers know that exercise can help some people feel better, and they also know that the bacteria in our gut may play a role in depression. This study will be the first to directly test whether exercise works partly by changing gut bacteria in people with depression.
Many people with depression don't respond well to current treatments like therapy or medication, so researchers need to find new ways to help. This study explores exercise as a possible addition to standard care because it may work through a different pathway—by changing the gut bacteria that scientists believe influence depression.

You will visit the research clinic 4 times over 12 weeks. Half of participants will continue their usual depression care (therapy, medication, or both) as they normally would. The other half will do the same usual care plus engage in aerobic exercise—like brisk walking, cycling, or jogging—at a moderate intensity for 12 weeks. Researchers will collect stool samples to examine your gut bacteria, ask about your mood and thinking, and track what you eat to understand how exercise might change your gut health and depression symptoms.
