概括

女拉克罗斯运动员的头部加速事件 (HAEs) 比男性运动员少,尽管冲击严重程度相似. 这项研究表明,需要更多的研究保护头盔在女子 Lacrosse.

科学领域:

运动医学运动医学
生物力学生物力学
伤害预防预防伤害

背景情况:

拉克罗斯的规则和装备在男性和女性球员之间有所不同.
关于女篮是否需要增强防护头盔的辩论存在,类似于男篮.
头部加速事件 (HAE) 是与拉克罗斯有关的头部伤害的一个关键问题.

研究的目的:

为了比较高中男生和女生橄球运动员之间的头部加速事件 (HAEs) 的速度和规模.
为了为正在进行的关于女篮防护头盔的讨论提供信息.
在HAE期间使用仪器口罩和有限元头模型分析头部动力学.

主要方法:

在2021赛季的26场比赛中,有17名高中 Lacrosse 球员 (女性6名,男性11名) 在2021赛季的26场比赛中佩戴仪器口罩.
使用时间窗口和视频审查来验证头部加速事件 (HAE).
将2021年的数据与上个赛季的数据结合起来,以驱动有限元头模型来模拟HAE并比较大脑组织菌株.

主要成果:

女子 Lacrosse 的 HAE 率大约比男性 Lacrosse 的 HAE 率低约 35% (0.21 比 0.33 个运动员暴露率).
峰值线性加速 (PLA),峰值角速度 (PAV) 和第95百分位数最大主要应变 (MPS95) 的中位数在女篮HAE中较低.
虽然女性的HAE大小较低,但这些差异在统计学上并不显著,并且该研究的样本规模很小.

结论:

与男性球员相比,女高中 Lacrosse 球员的头部加速事件的发生率较低.
头部加速事件的大小,虽然在女性中较低,但没有显示出统计学上显著的差异.
需要进一步研究更大的样本大小和仪器口罩数据,以最终解决女篮头部保护需求.

Impact Loading

Impact loading occurs when a moving object collides with a stationary structure, such as a rod with a uniform cross-sectional area fixed at one end. Under these conditions, the rod absorbs the kinetic energy from the striking object, leading to deformation and subsequent stress development. As the rod returns to its original position and reaches maximum stress, the absorbed energy, initially manifested as kinetic energy, transforms entirely into strain energy.
In cases of elastic deformation,...

Impact

Impact

Impact occurs when two bodies collide, leading to the application of impulsive forces between them. Analyzing impact mechanics involves considering two colliding particles moving along a line known as the line of impact, which passes through their centers and is perpendicular to the contact plane.
When particles with different initial velocities collide, they induce deformation by applying equal and opposite impulses. At the point of maximum deformation, the particles move together with...
