Finite element (FE) modeling provides a means to examine how global kinematics of repetitive head loading in sports influences tissue level injury metrics. FE simulations of controlled soccer headers in two directions were completed using a human head FE model to estimate biomechanical loading on the brain by direction. Overall, headers were associated with 95th percentile peak maximum principal strains up to 0.07 and von Mises stresses up to 1450 Pa, and oblique headers trended toward higher values than frontal headers but below typical injury levels. These quantitative data provide insight into repetitive loading effects on the brain.
有限元（FE）建模提供了一种方法，用于研究运动中重复性头部负荷的整体运动学如何影响组织水平的损伤指标。使用人体头部有限元模型完成了两个方向上受控足球头球的有限元模拟，以按方向估计大脑上的生物力学负荷。总体而言，头球与高达0.07的第95百分位数峰值最大主应变和高达1450 Pa的冯·米塞斯应力相关，并且斜向头球的数值有高于正向头球的趋势，但低于典型损伤水平。这些定量数据为了解对大脑的重复性负荷影响提供了见解。
