摘　　要：通过收集205位女性非竞技马拉松跑者和195位普通女性的足型数据,完成了两类女性人群的足型分类,并比较分析其足型差异。借助三维扫描仪获取包括长度、宽度、高度、围长、角度在内的23项足型数据,利用主成分分析降维,采用K-means聚类算法将普通女性人群足型分为短尖足、长宽足、短矮足,将非竞技马拉松女性跑者足型分为宽厚足、短窄足、窄平足,以探究非竞技马拉松女性跑者的足型规律;通过独立样本T检验分析,发现两类人群的足型在趾跖宽度、围长方面存在显著差异,非竞技马拉松女性跑者这两项指标的数值均大于普通女性人群。研究结论可以扩展非竞技马拉松女性跑者的足型数据库,并且为设计研制非竞技马拉松跑者的鞋楦提供一定的数据参考。In this study,data on foot types were collected from 205 non-compet itive female marathon runners and 195 ordinary women.The foot types of both groups were dlassified and compared,with 23 dimensions including length,width,height,girth,and angle obt ained using a 3D scanner.Principal component analysis was employed for dimensionality reduction,followed by K-means clustering to classify the general population's foot types into short pointed foot,long wide foot,and short foot.Non-competitive marathon runners'foot types were categorized into broad and thick foot,short and narrow foot,and narrow flafoot.This approach aimed to uncover the patterns of non-competitive marathon runners feet.Independent sample T-test analysis revealed significant differences in toe and plantar width as well as girth length between the two groups.These indexes were found to be greater in non-competitive marathon runners than in the general population.The findings of this study contribute to expanding the database on non-competitive female marathon runners'foot types,and provide certain data reference for the design and development of shoe last of non-competitive marathon runners.
