This study measured and compared the frequency, magnitude, and distribution of head impacts sustained by junior and adult Australian football players, respectively, and between player positions over a season of games. Twelve junior and twelve adult players were tracked using a skin-mounted impact sensor. Head impact exposure, including frequency, magnitude, and location of impacts, was quantified using previously established methods. Over the collection period, there were no significant differences in the impact frequency between junior and adult players. However, there was a significant increase in the frequency of head impacts for midfielders in both grades once we accounted for player position. A comparable amount of head impacts in both junior and adult players has implications for Australian football regarding player safety and medical coverage as younger players sustained similar impact levels as adult players. The other implication of a higher impact profile within midfielders is that, by targeting education and prevention strategies, a decrease in the incidence of sports-related concussion may result.
本研究分别测量并比较了澳大利亚青少年和成年足球运动员在一个赛季的比赛中头部撞击的频率、强度和分布情况，以及不同球员位置之间的差异。使用皮肤-mounted冲击传感器对12名青少年球员和12名成年球员进行跟踪。采用先前建立的方法对头撞击暴露情况进行量化，包括撞击的频率、强度和位置。在收集期间，青少年和成年球员之间的撞击频率没有显著差异。然而，一旦我们考虑了球员位置，两个级别中场球员的头部撞击频率都有显著增加。青少年和成年球员头部撞击次数相当，这对澳大利亚足球的球员安全和医疗覆盖有影响，因为年轻球员承受的撞击水平与成年球员相似。中场球员中较高撞击特征的另一个影响是，通过针对教育和预防策略，可能会降低与运动相关的脑震荡发生率。
