Despite growing interest in the biomechanical mechanisms of sports-related concussion, ice hockey and the youth sport population has not been studied extensively. The purpose of this pilot study was: 1) to describe the biomechanical measures of head impacts in youth minor ice hockey players; and, 2) to investigate the influence of player and game characteristics on the number and magnitude of head impacts. Data was collected from 13 players from a single competitive Bantam boy's (ages 13-14 years) AAA ice hockey team using telemetric accelerometers implanted within the players' helmets at 27 ice hockey games. The average linear acceleration, rotational acceleration, Gadd Severity Index and Head Injury Criterion of head impacts were recorded. A significantly higher number of head impacts per player per game were found for wingers when compared to centre and defense player positions (df=355, t=3.087, p=0.00218) and for tournament games when compared to regular season and playoff games (df=355, t=2.641, p=0.086). A significant difference in rotational acceleration according to player position (F2,1812=4.9551, p=0.0071) was found. This study is an initial step towards a greater understanding of head impacts in youth ice hockey.
尽管人们对与运动相关的脑震荡的生物力学机制越来越感兴趣，但冰球和青少年体育人群并没有得到广泛研究。本研究旨在：1）描述青少年冰球运动员头部撞击的生物力学测量值；2）研究运动员和比赛特点对头部撞击次数和撞击力度的影响。该研究从一个 13-14 岁的青少年 A 级 AAA 冰球男队的 13 名球员收集数据，使用安装在球员头盔内的遥测加速计在 27 场冰球比赛中收集数据。记录了头部撞击的平均线性加速度、旋转加速度、Gadd 严重指数和头部损伤准则。与中锋和防守球员相比，边锋球员的每场比赛的头部撞击次数明显更多（df=355，t=3.087，p=0.00218），与常规赛和季后赛相比，锦标赛比赛的头部撞击次数也更多（df=355，t=2.641，p=0.086）。根据球员位置，旋转加速度存在显著差异（F2,1812=4.9551，p=0.0071）。本研究是对青少年冰球头部撞击的初步研究。
