Effects of High-top and Low-top Basketball Shoes on Ankle Stability and Muscle Function during Landing

Purpose:To evaluate the effect of high-top and low-top basketball shoes on ankle inversion kinematics,ground reaction forces and relevant muscle activities,as well as the relationship between shoes and ankle stability during landing.Methods:13 subjects were required to wear high-top and low-top basketball shoes to land on an inversion plantarflexion tilting platform.Kinematics,ground reaction force and corresponding muscles activities of ankle were collected and analyzed.Result:No significant effect was found in inversion angle,maximum inversion angle velocity,and ground reaction force for vertical horizontal directions.However,high-top shoe showed a later onset of pre-activation than low-top shoe in four tilting conditions,especially at a 15° inversion condition(P0.05);meanwhile,the amplitude of pre-activation of peroneus longus and peroneus brevis for high-top shoe were smaller than low-top shoe at 15° inversion condition and 25° inversion plus 20° plantarflexion condition,respectively(P0.05).Conclusions:The high-top shoe selected in this study has little effects on ankle kinematics and ground reaction force,but has certain positive effects on ankle muscle pre-activation and limitation of range of motion.
