Effects of shoe collar height on sagittal ankle mechanics during weight-bearing dorsiflexion movement and lay-up jump

摘要

This study aims to investigate the effects of wearing high-top and low-top basketball shoes on the ankle joint kinematics, kinetics and performance in the sagittal plane during weight-bearing dorsiflexion (WB-DF) movement and lay-up jump. Twelve subjects performed WB-DF movement and lay-up jumps (LU) in two shoe conditions. Wearing HS can significantly reduce ankle joint excursion in WB-DF. No significant differences were found in jumping height and kinematics between the two shoes. In LU, peak plantarflexion torque and power were significantly lower in HS. The high-top shoes adopted in this study did not restrict the ankle dorsiflexion performance during actual jumping. But it is suggested that the greater power in LS during LU may have a greater potential in the actual game with different conditions, such as the distance of the shot and opposition. Thus, high shoe collar height would be applied to practical with the caution of affecting the partial kinetic characteristics of the ankle joint in the sagittal plane.
