The study was conducted to test the hypothesis that alterations in shoe gear can affect tibial strains in the human during dynamic loading. Rosette strain gauges were mounted on the medial border of the mid-diaphysis in two human subjects with a new strain gauge bonding technique using methyl methacrylate. Strain measurements were made at this site, the most frequent location for stress fractures in the Israeli Army during treadmill walking and free running while wearing various sport shoes (Rockport ProWalkers and New Balance NBX 900) and army boots (light Israeli infantry, double layered sole Israeli infantry, and Zohar infantry boots). Data were analyzed for only one of the subjects because strain gauge bonding was found to be inadequate at the time of surgical removal in the other subject. No single shoe lowered both the principal tibial compression and tensile strains, and the shear strains. The Zohar boot had the lowest principal compression strains during treadmill walking and mobile running, despite its relatively higher weight and sole durometry.
本研究旨在验证鞋具改变会影响人体在动态负荷下胫骨应变这一假设。采用甲基丙烯酸甲酯的新型应变片粘贴技术，将应变片安装在两名受试者胫骨干中段的内侧边缘。在该部位进行应变测量，该部位是以色列军队中应力性骨折最常见的位置，测量在跑步机行走和自由跑步时进行，受试者穿着各种运动鞋（罗克波特专业步行鞋和新百伦NBX 900）以及军靴（以色列轻型步兵靴、双层鞋底以色列步兵靴和佐哈尔步兵靴）。仅对其中一名受试者的数据进行了分析，因为在另一名受试者手术取出时发现应变片粘贴不充分。没有一种鞋能同时降低胫骨的主压缩应变、拉伸应变和剪切应变。尽管佐哈尔靴重量相对较重且鞋底硬度较大，但在跑步机行走和移动跑步时，其主压缩应变最低。
