摘要
针对青年非竞技运动员脚型研究较少的问题,文章利用三维人体足部测量技术,对122名18~35岁的女性和84名男性非竞技运动员进行脚型特点对比。采用主成分因子分析,将17项足部指标降维至4个独立和标准化变量,以提取的4个主成分为分类标准进行K-均值聚类,将男性脚型分为跖低足(39.29%)、低长足(25.00%)和跖高足(35.71%),女性脚型分为壮足(30.33%)、细足(36.06%)和高长足(33.61%)。此外,在以足长尺寸将脚型参数标准化后,还观察到脚型存在左右足及性别差异。研究结果可为运动鞋的设计和制作提供数据参考。
In view of the lack of research on foot shapes of young non-competitive athletes,the foot shape characteristics of 122 female and 84 male non-competitive athletes aged 18-35 were compared using 3D human foot measuring technique.Through principal component and factor analysis,17 foot indexes were reduced to 4 independent and standardized variables.With the four principal components extracted as the classification criteria,K-means clustering was carried out,male foot shapes were divided into low plantar foot(39.29%),low long foot(25.00%)and high plantar foot(35.71%),while female foot shapes were divided into sturdy foot(30.33%),slender foot(36.06%)and high long foot(33.61%).In addition,after foot shape parameters were standardized by foot length,it was also observed that there were differences between left and right feet and genders.The research results can offer a data reference for the design and manufacture of sneakers.
