Abstract

Objective – There is a high incidence of concussion and frequent utilization of Rapid Weight Loss (RWL) methods among combat sport athletes, yet the apparent similarity in symptoms experienced as a result of a concussion or RWL has not been investigated. This study surveyed combat sports athletes to...
