Abstract：
Combat sports, such as boxing and mixed martial arts [MMA], have the unique objective to finish a bout by way of knockout [KO] or technical knockout [TKO]. There are potentially both short- and long-term neurological injuries that can happen as a result of the repeated head trauma sustained in bouts, and thus it is imperative to identify the athletes that are at increased risk. Using an online database of professional boxing bouts [boxrec.com] over a 6-month period, KO/TKO rates were calculated across different states, weight classes, sex, and Fight Exposure Score [FES] categories. There was found to be a significant association between KO/TKO rates and weight class, sex, and FES category with heavyweights, males and FES 0 boxers having higher KO/TKO rates. KO/TKO rates were increased in winless boxers. KO/TKO rates across the states are documented in the study.
摘要：
战斗运动,如拳击和混合武术[MMA]，有独特的目标，通过淘汰赛[KO]或技术淘汰赛[TKO]完成回合。由于反复发作的头部创伤，可能会发生短期和长期的神经损伤，因此，必须识别风险增加的运动员。使用6个月内专业拳击比赛[boxrec.com]的在线数据库，KO/TKO率是在不同州计算的，体重等级,性别,和战斗暴露分数[FES]类别。发现KO/TKO比率与体重等级之间存在显着关联，性别,和重量级的FES类别，男性和FES0拳击手具有较高的KO/TKO率。无胜利拳击手的KO/TKO比率有所提高。研究中记录了各州的KO/TKO率。
