What this Trial Is About
This study aims to test whether aerobic exercise performed after fear extinction learning improves cognitive, physiological, and neural indices of extinction recall in a sample of trauma-exposed men and women with and without posttraumatic stress disorder (PTSD). Participants will complete a clinical intake visit (Day 0), followed by a three-day fear conditioning (day 1), fear extinction + activity (day 2), and fear extinction recall (day 3) protocol.
