摘要这项研究的目的是确定习惯性的极简主义跑鞋者是否具有据称的良好的跑步生物力学，以降低跑步损伤的风险，如初始负荷率。18名极简主义跑步者和16名传统软垫鞋跑步者在穿着他们喜欢的训练鞋和赤脚跑步时进行了评估。测量了踝关节和膝关节的动力学和运动学、初始加载速率和足击角度。还计算了踝关节和膝关节的矢状位刚度。双因素方差分析结果显示，当参与者穿鞋或赤脚跑步时，两组的初始负荷率没有差异；但是，当赤脚跑步时，两组的初始负荷率都增加了(p=0.008)。穿鞋跑步时，两组间脚踏角度有差异，而赤足时则无差异(最低限度运动者：8.71±8.99度，传统运动者：17.32±11.48度，P=0.002)。两组裸足跑步时踝关节僵硬程度均较低(p=0.025)。这些发现表明，受伤的危险因素在两组之间可能有所不同。鞋的结构差异确实改变了机械需求，然而，一旦习惯于特定鞋条件的需求，某些尖锐的有利或不利的反应可能会减弱。极简主义跑鞋在模仿习惯性赤脚跑步方面所谓的好处受到了质疑，受伤的风险可能不会减弱。
Abstract The aim of the study was to determine whether habitual minimalist shoe runners present with purported favorable running biomechanithat reduce running injury risk such as initial loading rate. Eighteen minimalist and 16 traditionally cushioned shod runners were assessed when running both in their preferred training shoe and barefoot. Ankle and knee joint kinetics and kinematics, initial rate of loading, and footstrike angle were measured. Sagittal ankle and knee joint stiffness were also calculated. Results of a two-factor ANOVA presented no group difference in initial rate of loading when participants were running either shod or barefoot; however, initial loading rate increased for both groups when running barefoot (p=0.008). Differences in footstrike angle were observed between groups when running shod, but not when barefoot (minimalist:8.71±8.99 vs. traditional: 17.32±11.48 degrees, p=0.002). Lower ankle joint stiffness was found in both groups when running barefoot (p=0.025). These findings illustrate that risk factors for injury potentially differ between the two groups. Shoe construction differences do change mechanical demands, however, once habituated to the demands of a given shoe condition, certain acute favorable or unfavorable responses may be moderated. The purported benefits of minimalist running shoes in mimicking habitual barefoot running is questioned, and risk of injury may not be attenuated.
