Prior studies have investigated associations between body mass index (BMI) and foot structure; however, these studies are limited only to the evaluation of the longitudinal arch of the foot and do not evaluate associations with body composition. Therefore, this study examined associations between body fat percentage (BFP) and muscle mass percentage with foot structure in adolescents. This study was conducted with 158 healthy subjects aged from 11 to 13 years. Body fat percentage and muscle mass percentage were estimated using bioelectrical impedance analysis. A podoscope was used to calculate Clarke's angle (CL), the Wejsflog index (WI), hallux valgus angle (ALPHA), and the angle of the varus deformity of the fifth toe (BETA). Lower values of CL were found in participants with excessive BFP ( = 0.021). No differences were observed in the values of the Wejsflog, ALFA or BETA indices between normal and excessive BFP groups. Participants with the lowest muscle mass percentage were significantly more likely to have lower values of CL and WI ( = 0.014 and < 0.001, respectively). Excess BFP appeared to have a significant effect on the longitudinal arch and low muscle mass percentage on the longitudinal and transverse arches of the foot in adolescents. There was no association between fat and muscle content with positions of the big and fifth toes.
先前的研究已经调查了体重指数（BMI）和足部结构之间的关联；然而，这些研究仅限于评估足部纵弓，而不评估与身体成分的关联。因此，本研究探讨了青少年体脂百分比（BFP）和肌肉质量百分比与足部结构之间的关系。本研究共纳入 158 名年龄在 11 至 13 岁的健康受试者。使用生物电阻抗分析来估计体脂百分比和肌肉质量百分比。使用足印器计算 Clarke 角（CL）、Wejsflog 指数（WI）、大脚趾外翻角（ALPHA）和第五脚趾内翻畸形角（BETA）。在体脂百分比过高的参与者中，CL 值较低（ = 0.021）。正常和体脂百分比过高组之间的 Wejsflog、ALFA 或 BETA 指数值没有差异。肌肉质量百分比最低的参与者 CL 和 WI 值明显较低（ = 0.014 和 < 0.001）。过多的体脂似乎对青少年的纵弓有显著影响，而低肌肉质量百分比对足的纵弓和横弓有显著影响。脂肪和肌肉含量与大脚趾和第五脚趾的位置之间没有关联。
