本研究提出了基于人群的多变量回归模型，用于预测足底压力，从容易测量的脚指标在穿鞋和赤脚人群跑步和步行任务。穿鞋和赤脚的模型都训练了50名参与者，并使用“留一法”验证，在两个人群中，步行和跑步的R2值为0.72-0.78，通过人体测量预测足底压力。当该模型在16个新数据集上进行盲测时，该模型在两个群体中的R2值为0.76-0.79。步行和跑步的峰值足底压力预测的准确性在两个人群中相似。结果表明，前足足底压力更敏感的拇趾距离赤脚的人与穿鞋的参与者表现出这种脚的特点反应不大。外侧前足足底压力是敏感的足弓指数在穿鞋和赤脚的参与者，但只有步行。在跑步过程中，足弓指数不是一个有用的决定因素的外侧前足压力。因此，习惯赤脚的人谁采用极简主义的鞋应该考虑额外的支持，在内侧前足和步行鞋应包括前足支持足弓指数（脚型）分层，但跑步鞋是具有挑战性的，由于在罢工模式的变化。
This study presents population-based multivariate regression models for predicting foot plantar pressure from easily measured foot metrics in both shod and barefoot populations for running and walking tasks. Both shod and barefoot models were trained on 50 participants and predicted plantar pressure from anthropometric measurements using a ‘leave-one-out’ validation withR2values of 0.72–0.78 across walking and running in both populations. When the model was blindly tested on 16 new data sets, the model performed just as well withR2values of 0.76–0.79 across both populations. Walking and running peak plantar pressure were predicted with similar levels of accuracy in both populations. It was revealed that forefoot plantar pressure was more sensitive to the hallux-toe distance in barefoot people with shod participants showing little response to this foot characteristic. Lateral forefoot plantar pressure was sensitive to the arch index in both shod and barefoot participants but only for walking. During running, the arch index was not a useful determinant of lateral forefoot pressure. Hence, habitually barefoot people who adopt minimalist footwear should consider additional support in the medial forefoot and walking footwear should include forefoot support stratified by arch index (foot type), but running footwear is challenging due to the variability in strike patterns.
