摘要
目的探讨穿着高、低帮篮球鞋对跳跃动作踝关节矢状面运动学、动力学以及运动表现的影响。方法利用Vicon运动捕捉系统和Kistler三维测力台同步采集12名受试者穿着高、低帮篮球鞋进行双腿落地反跳(drop jump,DJ)和单腿跨步跳(lay-up jump,LJ)过程中踝关节矢状面屈伸最小/最大角度、力矩、功率、刚度、跳跃高度以及背屈活动度等参数指标。结果 (1)穿着高帮鞋能够显著减小踝关节的背屈角度(P<0.05)。在DJ和LJ过程中,两款鞋的跳跃高度、踝关节触地角度、最小/最大角度、活动度均无显著性差异;(2)在DJ过程中,穿着两款鞋的踝关节屈伸动力学特征无显著差异;但在LJ过程中,穿着高帮鞋的跖屈力矩和功率峰值均显著小于低帮鞋(P<0.05)。结论穿着高帮鞋虽然没有限制跳跃情况下踝关节的屈伸表现,但会影响踝关节矢状面的部分动力学特征,建议鞋帮高度的选择和设计能够在护踝的基础上充分发挥踝关节在矢状面的力学作用,从而实现运动表现的最优化。
Objective To study the effects by wearing high-top and low-top basketball shoes on kinematics, kinetics and sports performance of ankle joint in sagittal plane under different jumping maneuvers. Methods Twelve subjects were required to wear high-top and low-top basketball shoes to perform drop jumps（DJ） and lay-up jumps（LJ）, and the parameters such as minimum/maximum joint angle, torque, power, stiffness, jumping height and dorsiflexion angle during their jumping maneuvers were simultaneously collected by the Vicon motion capture system and Kistler force plates. Results （1） The dorsiflexion angle of ankle joint was significantly decreased when wearing high-top basketball shoe （P〈0.05）. During DJ and LJ, no significant differences were found in jumping height, touch-down ankle angle, minimum/maximum ankle angle, and ankle range of motion （ROM） in the two shod conditions. （2） There were no significant differences in flexion/extension torque and power of ankle joint in the two shod conditions during DJ. However, during LJ, the peak value of plantarflexion torque and power from wearing high-top shoes was significantly smaller than that with low-top shoes （P〈0.05）. Conclusions Wearing high-top shoes do not restrict the performance of ankle plantarflexion and dorsiflexion under actual jumping situation. However, the kinetics of ankle joint in sagittal plane under different jumping maneuvers can be partly restricted. The selection and design of shoe collar height should be carefully considered to improve the mechanical effect of ankle joint in sagittal plane and optimize sports performance along with considering ankle protection.
