Injury reference curves for axial compressive forces on the neck were derived from impact tests of a spring-loaded tackling block on football helmets. Results suggest that helmets, especially those with resilient liners, reduce these forces.
颈部轴向压缩力的损伤参考曲线源自对橄榄球头盔上弹簧加载擒抱块的撞击测试。结果表明，头盔，尤其是那些带有弹性衬里的头盔，能降低这些力。
