Rates of anterior cruciate ligament (ACL) rupture in young people have increased markedly over the past two decades, with females experiencing greater growth in their risk compared to males. In this study, we determined the effects of low- and high-support athletic footwear on ACL loads during a standardized drop-land-lateral jump in 23 late-/post-pubertal females. Each participant performed the task unshod, wearing low- (Zaraca, ASICS) or high- (Kayano, ASICS) support shoes (in random order), and three-dimensional body motions, ground-reaction forces, and surface electromyograms were synchronously acquired. These data were then used in a validated computational model of ACL loading. One-dimensional statistical parametric mapping paired -tests were used to compare ACL loads between footwear conditions during the stance phase of the task. Participants generated lower ACL forces during push-off when shod (Kayano: 624 N at 71-84% of stance; Zaraca: 616 N at 68-86% of stance) compared to barefoot (770 N and 740 N, respectively). No significant differences in ACL force were observed between the task performed wearing low- compared to high-support shoes. Compared to barefoot, both shoe types significantly lowered push-off phase peak ACL forces, potentially lowering risk of ACL injury during performance of similar tasks in sport and recreation.
在过去二十年中，年轻人前交叉韧带（ACL）断裂的发生率显著增加，与男性相比，女性的风险增长更为明显。在本研究中，我们测定了23名青春期后期/青春期后的女性在进行标准化的下落-着地-侧向跳跃时，低支撑和高支撑运动鞋对ACL负荷的影响。每位参与者分别在不穿鞋、穿着低支撑鞋（Zaraca，亚瑟士）或高支撑鞋（Kayano，亚瑟士）的情况下（随机顺序）完成该任务，并同步采集三维身体运动、地面反作用力和表面肌电图。然后将这些数据用于经过验证的ACL负荷计算模型。在任务的站立阶段，使用一维统计参数映射配对检验来比较不同鞋类条件下的ACL负荷。与赤脚时相比（分别为770 N和740 N），参与者穿鞋时（Kayano：站立阶段71-84%时为624 N；Zaraca：站立阶段68-86%时为616 N）在蹬离阶段产生的ACL力较低。在穿着低支撑鞋与高支撑鞋完成任务时，未观察到ACL力有显著差异。与赤脚相比，两种鞋类均显著降低了蹬离阶段的ACL力峰值，这可能降低了在运动和娱乐中进行类似任务时ACL损伤的风险。
