摘要

足球在美国是一项受欢迎的青少年运动,但训练过程中反复的头部撞击对神经认知结果的影响尚不清楚。修改练习结构可能是减少足球运动中头部撞击和脑震荡风险的一种途径,但研究尚未确定常见足球活动中头部撞击的特征。本研究的目的是比较足球常见训练活动中的头部撞击暴露情况。八名在15岁及以下(U15)俱乐部球队练习的女足球运动员参与了这项为期两个足球赛季的研究。球员们在所有的练习和比赛过程中都佩戴了一个装有仪器的吹口传感器。研究人员记录了每个玩家进行的所有活动的持续时间,以表征玩家特定的暴露时间。进行电影回顾,以确定每次训练期间的头部接触事件,并根据球员正在进行的活动和训练对事件进行分类。根据峰值运动学和撞击率对每个运动员的头部撞击暴露进行量化。混合效应模型用于比较峰值运动学,广义线性模型用于比较不同演习和活动类型的冲击率。训练和活动类型与峰值运动学和冲击率相关。技术训练活动的暴露时间位居第二,与其他活动类型相比,其冲击率更高,平均运动学更低。团队互动活动和游戏与最高的旋转运动学相关,但影响率最低。女子青少年足球中的头部撞击暴露受到运动员所从事活动类型的影响。旨在减少青少年女子足球中头部撞击频率的干预措施可以受益于有针对性的技术训练活动;然而,旨在降低头部撞击程度的干预措施应针对团队互动和游戏活动。

Head Impact Exposure in Youth Soccer: Comparing across Activity Types
Soccer is a popular youth sport in the United States, but the effect of repetitive head impacts experienced during training on neurocognitive outcomes is not well understood. Modifying practice structure may be an avenue for reducing head impact exposure and concussion risk in soccer, but research has yet to characterize head impact exposure across common soccer activities. The objective of this study was to compare head impact exposure across common training activities in soccer. Eight female soccer players practicing on an age 15 and under (U15) club team participated in this study for two soccer seasons. Players wore an instrumented mouthpiece sensor during all practice and game sessions. Research personnel recorded duration of all activities performed by each player to characterize player-specific exposure time. Film review was performed to identify head contact events during each session and classify events according to the activity and drill the player was performing. Head impact exposure for each athlete was quantified in terms of peak kinematics and impact rate. Mixed effects models were used to compare peak kinematics and generalized linear models were used to compare impact rates across drills and activity type. Drill and activity type were associated with peak kinematics and impact rate. Technical training activities accounted for the second-highest exposure time and were associated with higher impact rates and lower mean kinematics than other activity types. Team interaction activities and game play were associated with the highest rotational kinematics but the lowest impact rates. Head impact exposure in female youth soccer is influenced by the type of activity in which the athlete is engaged. Interventions designed to reduce head impact frequency in female youth soccer can benefit from targeting technical training activities; whereas, interventions designed to reduce head impact magnitude should target team interaction and game activities.
