In youth ice hockey, girls are reported to suffer more concussions than boys, peaking around 13-14 years old, which may be related to differences in the level of brain trauma experienced by the players. The purpose of this research was to describe the differences in brain trauma characteristics, specifically the magnitude and frequency of head impacts between Peewee boys and girls from playing ice hockey. Thirty games of Peewee boys and Peewee girl's ice hockey were recorded to document the head impact events. These events were reconstructed using physical and computational techniques to estimate the strain to the brain tissue. The results found that Peewee boys experienced more head impacts than girls, specifically from the shoulder, ice, boards, and fist/punches (p < 0.05). The boys also experienced more medium strain category impacts (p < 0.05). These results identify that Peewee boys and girls engage in ice hockey differently, which affects the risk of brain trauma likely to be encountered while during game play, suggesting that the increased rate of concussion for girls may not be related to impact magnitudes within the sport but increased reporting of symptoms of concussion or gender differences in brain tissue response to an impact.

Peewee男孩和女孩在青少年冰球比赛中头部撞击的频率和幅度比较

据报道，在青少年冰球比赛中，女孩比男孩遭受更多的脑震荡，在 13-14 岁左右达到高峰，这可能与球员经历的脑外伤程度不同有关。本研究的目的是描述脑外伤特征的差异，特别是 Peewee 男孩和女孩因打冰球而头部撞击的程度和频率。记录了 Peewee 男孩和 Peewee 女孩冰球的 30 场比赛，以记录头部撞击事件。这些事件是使用物理和计算技术重建的，以估计脑组织的应变。结果发现 Peewee 男孩比女孩经历了更多的头部撞击，特别是来自肩部、冰块、木板和拳头/拳头的撞击（p < 0.05）。男孩们还经历了更多的中等应变类别影响（p < 0.05）。这些结果表明 Peewee 男孩和女孩从事冰球运动的方式不同，这会影响在比赛期间可能遇到的脑外伤风险，这表明女孩脑震荡率的增加可能与运动中的影响程度无关，但脑组织对撞击反应的脑震荡症状或性别差异的报告增加。
