With the increased national concern about concussions in football, recent research has focused on evaluating the impact performance of modern football helmets. Specifically, this technical note offers a biomechanical analysis of classic leather helmets compared with modern helmets. Furthermore, modern helmets were examined to illustrate the performance differences between the better- and worse-performing ones. A total of 1224 drop tests were performed from a range of drop heights and impact locations on 11 different helmet types (10 modern and 1 leather helmet model). The resulting head acceleration was used to assess the risk of concussion for each drop test. The results of this analysis demonstrate that modern helmets are significantly and substantially superior to leather helmets in all impact scenarios, and that notable differences exist among modern helmets.
随着全国范围内对足球脑震荡问题的日益关注，最近的研究集中在评估现代足球头盔的冲击性能上。具体来说，本技术说明对经典皮革头盔与现代头盔进行了生物力学分析。此外，还对现代头盔进行了检查，以说明性能更好和性能更差的头盔之间的差异。总共对 11 种不同类型的头盔（10 种现代头盔和 1 种皮革头盔模型）进行了 1224 次从不同跌落高度和冲击位置的跌落测试。使用所得头部加速度来评估每次跌落测试的脑震荡风险。分析结果表明，在所有冲击情况下，现代头盔都明显优于皮革头盔，而且现代头盔之间存在显著差异。
