Researchers are striving to understand the biomechanics of concussive injury that occur in the context of sport by using a number of methodologies. Animal models, video reconstruction, and helmet-based accelerometers have all been used, but have their limitations. The Head Impact Telemetry (HIT) System permits the real-time in vivo tracking of all impacts that occur on the football field and has been used in both the high school and collegiate setting. This review provides a theoretical discussion of concussion mechanics and examines the current literature on the effects of the number of impacts, impact magnitude, impact distribution, and concussion threshold in high school and collegiate football athletes recorded by the HIT System.
研究人员正在努力通过使用多种方法来理解运动背景下震荡性损伤的生物力学。动物模型、视频重建和基于头盔的加速度计都已被使用，但它们都有局限性。头部撞击遥测系统（HIT）允许实时活体跟踪足球场上发生的所有撞击，并已在高中和大学环境中使用。本文综述了震荡机制的理论讨论，并研究了 HIT 系统记录的高中和大学足球运动员的撞击次数、撞击幅度、撞击分布和震荡阈值的影响的当前文献。
