What is a Repetitive Concussion in Sports?

OBJECTIVES Athletes are in a unique situation where they experience repeated concussions while participating in competitions. Although repeated exposure to a concussion has a high risk of negatively affecting athletes' performance and health after retirement, awareness of it is very low in athletes and sports associations. Therefore, the purpose of this review is to provide the basic information about the concussion problem that occurs repeatedly in sports and to establish the plan for the concussion reduction strategy. METHODS To provide the basic information related to a concussion problem in sports, the narrative review was applied. RESULTS The definition, symptoms and symptoms of a sports-related concussion, second impact syndrome, long-term sequelae from the concussion, the preventive effect of the helmet, and the guideline for the safe return to sports after concussion were discussed. CONCLUSIONS This study has reviewed the lack of awareness of concussions that occur repeatedly in the sports field and the problems related to the safety and health of the athletes. In order to reduce a concussion incidence and surrounding issues, the concussion reduction strategy has been proposed, and persistent interest is required from athletes, coaches, parents, and related sports organizations in relation to concussions.
