[Purpose] The association between foot injuries and foot alignment, including the transverse arch height (TAH) and asymmetry, was examined in athletes participating in college track events. [Participants and Methods] This study included 55 male athletes participating in a college track and field club. Data including demographic information and the incidence of foot injuries within a year prior to participation in this study were obtained via questionnaires. TAH and the medial longitudinal arch height during 10 and 90% loading, leg-heel alignment, and the heel angle were measured before calculating the asymmetry of each alignment parameter measured. Participants were categorized into an injury or a normal group. Unpaired t-tests were used to perform between-group comparisons for each alignment parameter measured and asymmetry. Additionally, logistic regression analysis was performed to identify factors associated with foot injuries after adjustment for demographic data. [Results] TAH asymmetry during 10 and 90% loading was significantly greater in the injury group. Further logistic regression analysis performed showed that only TAH asymmetry during 90% loading was significantly associated with foot injuries after adjustment for demographic data. [Conclusion] With regard to track events, a greater asymmetry of forefoot TAH in a weight-bearing position was observed to be associated with foot injuries.
[目的] 本研究在参加大学田径项目的运动员中，探讨足部损伤与足部排列（包括横弓高度（TAH）和不对称性）之间的关联。[参与者与方法] 本研究纳入了55名参加大学田径俱乐部的男性运动员。通过问卷调查获取包括人口统计学信息以及参与本研究前一年内足部损伤发生率的数据。在计算所测量的每个排列参数的不对称性之前，测量10%和90%负荷时的TAH以及内侧纵弓高度、腿 - 足跟排列和足跟角度。将参与者分为损伤组和正常组。对所测量的每个排列参数和不对称性进行组间比较时采用独立样本t检验。此外，在对人口统计学数据进行调整后，进行逻辑回归分析以确定与足部损伤相关的因素。[结果] 损伤组在10%和90%负荷时的TAH不对称性显著更大。进一步进行的逻辑回归分析表明，在对人口统计学数据进行调整后，仅90%负荷时的TAH不对称性与足部损伤显著相关。[结论] 对于田径项目，观察到在负重位置时前足TAH的更大不对称性与足部损伤有关。
