Introduction: Concussions are a physiologically & psychologically stressful event. Stress markers may provide insight into concussion recovery, but have not been examined. Purpose & Method: To investigate the stress response of concussed athletes compared to controls from injury to post-RTP. Concussed athletes’ Mood states, Perceived Stress, HRV, and Morning & Afternoon Cortisol were assessed at 3 phases of recovery following concussion. Results: Repeated measures ANOVA revealed significant interactions for TMD, Depression, Anger, Confusion, Fatigue, HF norm (rest), LF norm (rest), HF norm (difference between sitting & standing), LF norm (difference between sitting & standing), and LF/HF ratio (difference between sitting & standing). Vigor & Tension demonstrated significant changes over time in the concussed group. Significant difference between the two groups for morning Cortisol levels at phase 3 was revealed. Conclusion: Concussed athletes display elevated levels of stress post-injury. Findings warrant further investigation of stress markers in concussed athletes during recovery.
