Abstract

This study quantified head impact exposures for Canadian university football players over their varsity career. Participants included 63 players from one team that participated in a minimum of 3 seasons between 2013 and 2018. A total of 127,192 head impacts were recorded from 258 practices and 65 games. The mean (SD) number of career impacts across all positions was 2023.1 (1296.4), with an average of 37.1 (20.3) impacts per game and 7.4 (4.4) impacts per practice. The number of head impacts that players experienced during their careers increased proportionally to the number of athletic exposures (P < .001, r = .57). Linebackers and defensive and offensive linemen experienced significantly more head impacts than defensive backs, quarterbacks, and wide receivers (P ≤ .014). Seniority did not significantly affect the number of head impacts a player experienced. Mean linear acceleration increased with years of seniority within defensive backs and offensive linemen (P ≤ .01). Rotational velocity increased with years of seniority within defensive backs, defensive and offensive linemen, running backs, and wide receivers (P < .05). These data characterize career metrics of head impact exposure for Canadian university football players and provide insights to reduce head impacts through rule modifications and contact regulations.

加拿大大学足球运动员职业生涯头部撞击暴露分析。

这项研究量化了加拿大大学足球运动员在其大学生涯中的头部撞击暴露。参与者包括来自一支球队的63名球员，他们在2013年至2018年期间至少参加了3个赛季。在258次训练和65场比赛中，共记录了127,192次头部撞击。所有位置的职业生涯影响的平均(SD)数量为2023.1(1296.4)，平均每场比赛影响37.1(20.3)，每次练习影响7.4(4.4)。运动员在职业生涯中经历的头部撞击次数与运动暴露次数成比例增加(P < 0.001, r = 0.57)。线卫、防守和进攻线卫比防守后卫、四分卫和外接球手更容易受到头部撞击(P≤0.014)。资历对玩家经历的头部撞击次数没有显著影响。防守后卫和进攻锋线球员的平均线性加速度随年龄增长而增加(P≤0.01)。防守后卫、防守和进攻线卫、跑卫和外接手的轮转速度随年龄增长而增加(P < 0.05)。这些数据描述了加拿大大学足球运动员头部撞击暴露的职业指标，并为通过规则修改和接触规定减少头部撞击提供了见解。

期刊介绍： The mission of the Journal of Applied Biomechanics (JAB) is to disseminate the highest quality peer-reviewed studies that utilize biomechanical strategies to advance the study of human movement. Areas of interest include clinical biomechanics, gait and posture mechanics, musculoskeletal and neuromuscular biomechanics, sport mechanics, and biomechanical modeling. Studies of sport performance that explicitly generalize to broader activities, contribute substantially to fundamental understanding of human motion, or are in a sport that enjoys wide participation, are welcome. Also within the scope of JAB are studies using biomechanical strategies to investigate the structure, control, function, and state (health and disease) of animals.
