Recently, protective headgear has been released for women's lacrosse despite the fact that contact to the head is illegal. The purposes of this study were to (1) compare the linear and rotational impact attenuation properties of 2 brands of lacrosse headgear at 4 different locations during laboratory pendulum impacts and (2) determine impact dissipation of new and used lacrosse headgear. We measured peak rotational acceleration (PRA; rad/s2) and linear acceleration (PLA; g) at 4 impact locations (side, rear boss non-centric (NC), front boss, and front) in two headgear brands (Cascade LX, Hummingbird). Two headgear service lives (new headgear, used headgear) were included for the second analysis. During the slower speed, there was a significant interaction between impact location and helmet brand (p = 0.002) for PLA. No other findings were significant. While the Hummingbird headgear reduced linear and rotational accelerations of the headform better than the Cascade headgear during slow velocity impacts to the front and front boss locations, it did so due to extreme motion of the helmet upon impact that we believe may compromise protection of the head and face from lacerations and other injuries.

女子曲棍网兜球头盔的缓解冲击性能。

最近，尽管女子头部曲棍球与头部的接触是非法的，但已为女子曲棍球提供了防护性头盔。这项研究的目的是（1）在实验室摆锤撞击期间比较两个品牌的曲棍网兜球头盔在4个不同位置的线性和旋转冲击衰减特性，以及（2）确定新的和使用的曲棍网兜球头盔的冲击消散。我们测量了两个头盔品牌（Cascade LX，CX和LX）在4个撞击位置（侧面，后轮毂非中心（NC），前轮毂和前部）的四个撞击位置的峰值旋转加速度（PRA; rad / s2）和线性加速度（PLA; g）。蜂鸟）。第二个分析包括两个头盔的使用寿命（新头盔，二手头盔）。在较慢的速度下，PLA的撞击位置与头盔品牌之间存在显着的相互作用（p = 0.002）。没有其他发现是有意义的。尽管在对前方和前轮毂位置进行慢速撞击时，蜂鸟头饰比Cascade头饰能更好地降低头模的线性和旋转加速度，但这样做是由于头盔在撞击时的剧烈运动，我们认为这可能会危及对头部的保护以及因割伤和其他伤害而面对。
