- Abstract
Introduction: Previous research has investigated the relationship between the morphology of intrinsic foot muscles and post-jump landing posture control ability in adolescent athletes (Arima et al., 2022). However, gender differences in this relationship are still not clearly understood. Objectives: This study aimed to investigate the relationship between the intrinsic foot muscles morphology, toe grip strength, and post-jump landing posture control ability in adolescent athletes, considering gender differences. Study design: This study is cross-sectional design. Methods: A total of 171 adolescent athletes (104 males and 67 females) were included. The cross-sectional area (CSA) and thickness of the abductor hallucis, flexor hallucis brevis (FHB), and flexor digitorum brevis (FDB) were measured by an ultrasound system. Toe grip strength was assessed with a digital grip strength meter. The single-leg forward jump landing stability was evaluated using the Dynamic Postural Stability Index (DPSI), calculated from the combined medial-lateral, vertical, anterior-posterior stability index (APSI). Correlations between each variable were calculated for gender, and the relationships were examined using multiple regression analysis. Results: In males, there was a significant correlation between the CSA and thickness of FHB, toe grip strength, and DPSI (p < 0.05). For females, significant correlations were observed between the CSA of FHB and DPSI, as well as the CSA of FDB and thickness with APSI (p < 0.05). Multiple regression analysis indicated that in males, the CSA of FHB and toe grip strength, while in females, the CSA of FHB and FDB were significantly associated with DPSI (p < 0.05). Conclusions: The findings suggest that overall toe grip strength contributes to post-jump landing stability in males, while in females, the FDB, which is widely attached to the sole and contributes to foot stiffness, generates stability. Support for adolescent athletes needs to consider the gender differences between toe grasp and FDB function.
