Relationship between vasoreactivity and exercise-related symptom exacerbation in adolescents following concussion


  • Hemodynamic responses to exercise do not differ significantly between concussed and healthy adolescents, and the percentage of maximum heart rate (HR) where arterial carbon dioxide (CO2) begins to decline during exercise contributes to exercise-mediated symptom exacerbation in concussed individuals.

Why this matters

  • Studies examining physiological responses to post-concussion exercise are limited.

  • Results from this study may provide direction for concussion rehabilitation plans, allowing clinicians to develop personalized exercise volume plans to maximize concussion treatment.
