Abstract

Head injuries are dangerous injuries that are common in combat sports. Nevertheless, the mechanisms of concussion in sport have are not precisely known. Thus, this study aimed to investigate the dynamic response of the head based on linear and rotational accelerations in boxing using computer simulation. The ADAMS software model was used to determine the linear and rotational acceleration of boxing’s straight punch. The peak linear acceleration, average linear acceleration, peak rotational acceleration, and average rotational acceleration resulted from the straight punch to head were obtained: 75 g, 20 g, 4036 rad/s², 1140 rad/s², respectively; the impact times were 30 ms and 3 ms, respectively. The comparison of acceleration tolerance thresholds of head injury and obtained results of this study showed the rotational acceleration only leads to head injury. Furthermore, it is biomechanically improbable that the head would be moved only translationally or rotationally as a result of a straight punch. Therefore, both rotational and linear accelerations should be observed together for future studies.

头部对拳击冲击的动态响应的计算机模拟研究

头部受伤是格斗运动中常见的危险伤害。然而，体育运动中脑震荡的机制尚不清楚。因此，本研究旨在利用计算机模拟研究基于线性和旋转加速度的头部动态响应。采用ADAMS软件模型确定拳击直冲的直线加速度和旋转加速度。直线冲头产生的峰值线加速度、平均线加速度、峰值旋转加速度和平均旋转加速度分别为75 g、20 g、4036 rad/s²、1140 rad/s²;冲击时间分别为30 ms和3 ms。头部损伤的加速度耐受阈值与本研究所得结果的比较表明，旋转加速度只导致头部损伤。此外，从生物力学角度来看，头部不太可能因为直拳而只发生平移或旋转运动。因此，在未来的研究中，旋转加速度和线性加速度应该一起观察。
