How many concussions would it take for athletes to choose to discontinue participation in their primary sport?

Abstract

The process by which athletes decide to continue or discontinue sport participation after concussion has not been explicated. Intercollegiate and club sport athletes (n = 394) completed an online survey that included assessments of demographic factors, the total number of concussions (and anterior cruciate ligament (ACL) tears) that would prompt sport retirement, concussion history, and athletic identity. On average, participants reported that they would retire from their primary sport after sustaining 3 to 4 concussions (and approximately 2 ACL tears). The total number of concussions reported was negatively correlated with the number of additional concussions it would take to precipitate sport retirement. Athletic identity was positively associated with the number of concussions that participants with a history of one or more concussions reported would prompt them to retire from their primary sport. The results provide information of potential utility to professionals implementing concussion education programs and working with athletes at risk of experiencing concussion.
