Barefoot running has been increasing in popularity, yet there is a gap in understanding concerning the biomechanics of mid-distance barefoot running, especially between genders and runners of different running-experience levels. This study examines the effects of running-experience, gender, and their interaction on running biomechanics following 5 km barefoot running. Before and after a 5 km run, three-dimensional kinematics and kinetics of the lower limb joints and plantar pressure during barefoot running were collected from 20 participants. Participants were stratified by their running-experience levels (novice and marathon-experienced) and gender. This study revealed significant gender effects on lower limb biomechanics following a 5 km barefoot run. Increased plantar pressure under the lateral aspect of the foot was observed in the female cohort, while the male cohort exhibited reduced plantar pressure under the lateral heel. This study suggests that modified lower limb running biomechanics and modified lateral foot loading after 5 km barefoot running may create a different foot loading environment for female and male runners that should be accommodated in barefoot runningand minimalist shoe design.
赤脚跑步越来越受欢迎，但对于中距离赤脚跑步的生物力学，特别是在性别和不同跑步经验水平的跑者之间，仍然存在理解上的差距。本研究考察了跑步经验、性别及其相互作用对 5 公里赤脚跑步后跑步生物力学的影响。在 5 公里跑步前后，从 20 名参与者中收集了赤脚跑步时下肢关节的三维运动学和动力学以及足底压力的数据。参与者按跑步经验水平（新手和马拉松经验丰富者）和性别分层。本研究表明，5 公里赤脚跑步后，下肢生物力学存在显著的性别差异。女性组观察到外侧足部的足底压力增加，而男性组则表现出外侧足跟的足底压力降低。本研究表明，5 公里赤脚跑步后，下肢跑步生物力学的改变和外侧足部负荷的改变可能为女性和男性跑者创造了不同的足部负荷环境，这在赤脚跑步和极简鞋设计中需要加以考虑。
