A great many interventions for posttraumatic stress disorder (PTSD) in adults have been described in the literature. These include, but are not limited to, cognitive-behavioral therapy, psychodynamic therapy, psychopharmacology, exposure therapy, anxiety management training, stress management techniques, eye movement desensitization and reprocessing, and physical exercise. In contrast, there is limited research and empirical support for evaluating treatment interventions for children diagnosed with PTSD. This article focuses specifically on the role of exercise in reducing not only PTSD but also the major components that are associated with PTSD, such as anxiety and depression. It emphasizes that exercise fits in naturally with the ecological framework of children and with their educational curricula.
