Abstract
BACKGROUND
This study explored the relationship between foot types and corresponding variations in shock attenuating properties of the heel.
METHODS
Thirty matched participants were assigned to 3 groups: pronated, neutral, and supinated. A low-mass accelerometer was mounted to the calcaneus of the right leg of each participant.
RESULTS
Acceleration at heel strike for supinators was significantly higher than that in individuals with pronated and neutrally aligned feet. No significant difference was found in mean and maximum acceleration at heel strike between pronators and neutrals.
CONCLUSION
Cavus feet undergo significantly higher mean and maximum acceleration forces than neutrally aligned and pronated feet.
摘要
背景
本研究探讨了足型与足跟减震特性相应变化之间的关系。
方法
30名匹配的参与者被分为3组：旋前足、中立足和旋后足。在每位参与者的右足跟骨上安装一个低质量加速度计。
结果
旋后足在足跟触地时的加速度显著高于旋前足和中立足个体。旋前足和中立足在足跟触地时的平均加速度和最大加速度没有显著差异。
结论
高弓足承受的平均加速度和最大加速度力显著高于中立足和旋前足。
