A golf-related ACL injury can be linked with excessive golf play or practice because such over-use by repetitive golf swing motions can increase damage accumulation to the ACL bundles. In this study, joint angular rotations, forces, and moments, as well as the forces and strains on the ACL of the target-side knee joint, were investigated for ten professional golfers using the multi-body lower extremity model. The fatigue life of the ACL was also predicted by assuming the estimated ACL force as a cyclic load. The ACL force and strain reached their maximum values within a short time just after ball-impact in the follow-through phase. The smaller knee flexion, higher internal tibial rotation, increase of the joint compressive force and knee abduction moment in the follow-through phase were shown as to lead an increased ACL loading. The number of cycles to fatigue failure (fatigue life) in the ACL might be several thousands. It is suggested that the excessive training or practice of swing motion without enough rest may be one of factors to lead to damage or injury in the ACL by the fatigue failure. The present technology can provide fundamental information to understand and prevent the ACL injury for golf players.
与高尔夫相关的前交叉韧带损伤可能与过度的高尔夫运动或练习有关，因为重复性的高尔夫挥杆动作导致的这种过度使用会增加前交叉韧带束的损伤积累。在本研究中，使用多体下肢模型对10名职业高尔夫球手的关节角旋转、力和力矩，以及目标侧膝关节前交叉韧带的力和应变进行了研究。通过将估计的前交叉韧带力假定为循环载荷，还预测了前交叉韧带的疲劳寿命。在前挥杆阶段击球后不久，前交叉韧带的力和应变在短时间内达到最大值。在后随动作阶段，较小的膝关节屈曲、较高的胫骨内旋、关节压缩力的增加以及膝关节外展力矩的增加均显示会导致前交叉韧带负荷增加。前交叉韧带疲劳失效的循环次数（疲劳寿命）可能为数千次。建议在没有足够休息的情况下过度训练或练习挥杆动作可能是导致前交叉韧带因疲劳失效而受损或受伤的因素之一。本技术可为理解和预防高尔夫球手的前交叉韧带损伤提供基础信息。
