Grappling With Trauma: Brazilian Jiu-Jitsu for First Responders

This study explores whether participating in an 8-week Brazilian Jiu-Jitsu (BJJ) program is linked to changes in trauma-related symptoms among first responders. Many first responders experience ongoing stress or exposure to traumatic events, and some prefer physical, movement-based activities rather than traditional clinical services to support their well-being. In this study, participants will attend BJJ classes one to two times per week for eight weeks. They will also complete short daily and weekly questionnaires about mood, stress, and well-being, write brief weekly reflections, and participate in a one-on-one interview after the program. The study aims to understand both symptom patterns and participants' personal experiences with emotional regulation and overall wellness during the program. This study does not provide mental health treatment and will not diagnose or treat PTSD. Instead, it examines whether BJJ, as a non-clinical physical activity, may offer supportive benefits for first responders.
