运动员过度使用损伤的风险很高，部分原因是下肢的重复负荷。与正常足弓（NA）结构的个体相比，高足弓（HA）或低足弓（LA）的个体发生特定过度使用损伤（包括应力性骨折）的风险可能会增加。高的内侧纵向足弓可能由于足部力学的刚性增加而导致减震性能降低。虽然在直线行走和跑步中已经研究了拱形结构对动态功能的影响，但在多方向运动中两者之间的关系尚未研究。本研究的目的是确定足球运动员在步行和旋转运动期间是否存在足底负荷差异。对26名参与者（16名NA，10名HA）的足部9个区域进行了足底负荷检查。高足弓运动员在行走时表现出外侧后足和内侧前足的最大力增加，内侧前足的力时间积分增加。HA运动员在快速旋转过程中也表现出内侧后足和内侧及中央前足的最大力增加。目前的研究结果表明，高足弓结构和正常足弓结构的足球运动员之间的负荷模式不同，这可能会影响该人群的受伤风险。
Risk of overuse injury among athletes is high due in part to repeated loading of the lower extremities. Compared to individuals with normal arch (NA) structure, those with high (HA) or low arch (LA) may be at increased risk of specific overuse injuries, including stress fractures. A high medial longitudinal arch may result in decreased shock absorbing properties due to increased rigidity in foot mechanics. While the effect of arch structure on dynamic function has been examined in straight line walking and running, the relationship between the two during multi-directional movements remains unstudied. The purpose of this study was to determine if differences in plantar loading in football players occur during both walking and pivoting movements. Plantar loading was examined in 9 regions of the foot for 26 participants (16 NA, 10 HA). High arch athletes demonstrated increased maximum force in the lateral rear foot and medial forefoot, and force time integral in the medial forefoot while walking. HA athletes also demonstrated increased maximum force in the medial rear foot and medial and central forefoot during rapid pivoting. The current findings demonstrate that loading patterns differ between football players with high and normal arch structure, which could possibly influence injury risk in this population.
