The Features of Foot Morphology and Intrinsic Foot Muscle Property in Adolescent Swimmers: An Ultrasound-Based Study

This cross-sectional study aimed to investigate the relationship between foot shape and intrinsic muscles (IFMs) in adolescent swimmers compared with other athletes. Foot morphology of was athletes comparable age a competition level (n = 32 [64 feet]; total 64 feet; 128 feet two groups). variables IFMs were measured using three-dimensional scanner an ultrasound imaging system, respectively. Multiple linear regression analysis forced entry performed clarify association thickness area (CSA) IMFs navicular height both sitting standing positions. Navicular position, abductor hallucis (AbH) flexor digitorum brevis (FDB), as well CSA significantly lower (p < 0.05). A larger for (FHB) observed than 0.01). The positions positively correlated FHB FDB showed that associated (β 0.395; p 0.002, β 0.201; 0.018). elite Furthermore, swimmers’ high FDB, suggesting might be more involved formation medial longitudinal arch AbH.
