Exercise after fear training boosts PTSD recovery in new study

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Age 18 - 55 years of age * Currently experiencing at least 4 PTSD symptoms with at least 1 re-experiencing symptom (e.g., trauma memory intrusion, trauma nightmares, trauma flashbacks, intense emotional distress related to trauma, or marked physiological reactivity related to trauma) from criterion B. * English speaking * Medically healthy Exclusion Criteria: * being pregnant * having a history of light headedness or fainting during physical activity * having a history of chest pain during physical activity * having a bone, joint, cardiac, or other medical condition that a doctor has said may be worsened by physical activity * responding 'Yes' to any of the seven questions on the Physical Activity Readiness Questionnaire (PAR-Q; unless they provide a doctor's note indicating that it is safe for them to engage in aerobic exercise ) * percutaneous coronary intervention or acute myocardial infarction in the last 6 weeks * unstable arrhythmias/implanted cardiac defibrillator shocks in the last 3 months * Internal ferromagnetic objects (such as electronic devices, surgical implants, shrapnel, etc.) * Nonremovable dental implants, such as braces or upper permanent retainers, as these will distort the MRI images we collect (note: filings, crowns, and silver or gold teeth are OK) * Any other condition, medication, or implant that the investigator believes would degrade image quality or render data unusable * psychotic disorders * Permanent makeup or tattoos with metallic dyes, * A self-reported history of loss of consciousness (greater than 30 minutes) * physical disabilities that prohibit task performance (such as blindness or deafness) * Any other condition that the investigator believes might put the participant at risk * Claustrophobia * History of cardiovascular disease * on-going traumatic event exposure (e.g., living with an abusive partner) * Severe substance use disorder. * unstable medication (changes within the past \~4 weeks) * Acute sedatives/pain killers (e.g., benzodiazepines, Vicodin) and prescription stimulants (e.g., Adderall) would not be permitted for 6 hours prior to the study visit.
