Slap fighting is a fast-paced combat sport wherein athletes strike each other in the head with open hands and matches are largely scored by points or knockouts. Power Slap,¹ a slap fighting promotion that has offered a platform for this largely underground sport, was first televised in January 2023 and has drawn extensive criticism from both medical and nonmedical personnel.² Worryingly, the promotional video for Power Slap³ features several contestants exhibiting signs of concussion. While there is a general consensus regarding the severity of this sport, to our knowledge, a quantification of the concussion risk has yet to be reported. The goal of this study was to identify signs of concussion among slap fighters by performing a video analysis.
