This study examined the influence of basketball shoe midsole inserts with different forefoot and rearfoot rebound properties on biomechanical loading and subjective perception during a side-cutting maneuver. Eleven male basketball players executed side cutting in four shoe conditions mechanically characterized for their rearfoot/forefoot rebound: compliant/compliant, springy/springy, compliant/springy, and springy/compliant. Lower extremity kinetics and kinematics (normalized to body mass), as well as subjective perception, were measured. During the weight-acceptance phase, there were no differences between shoes in all biomechanical variables, except a slightly greater ankle range of motion (1.2° greater than the other three shoes) in the frontal plane for shoe compliant/springy. During the push-off phase, shoe springy/springy led to a greater ankle plantarflexion moment (1.21 Nm/kg greater than the other three shoes, p < 0.001) and knee internal rotation moment (0.09 Nm/kg greater than the other three shoes, p = 0.012), while shoe compliant/springy resulted in a greater ankle range of motion in the frontal plane (1.4° greater than the other three shoes, p < 0.001). Perception data showed no statistically significant difference among any shoes. In conclusion, springy inserts of basketball shoe midsoles induced a biomechanical loading effect. Perception of players being unaffected indicates the importance of biomechanical evaluation to examine the effects of the given shoe modifications during side cutting.

具有不同机械回弹特性的篮球鞋中底衬垫对侧切动作中生物力学载荷和主观感知的影响

本研究检验了具有不同前足和后足回弹特性的篮球鞋中底衬垫对侧切动作中生物力学载荷和主观感知的影响。11 名男篮球运动员在四种鞋子条件下执行侧切，其后脚/前脚回弹具有机械特征：柔顺/柔顺、弹性/弹性、柔顺/弹性和弹性/柔顺。测量了下肢动力学和运动学（标准化为体重）以及主观感知。在承重阶段，鞋子之间在所有生物力学变量上没有差异，除了鞋的柔顺性/弹性在额平面上的脚踝运动范围稍大（比其他三款鞋大 1.2°）。在推开阶段，鞋弹性/弹性导致更大的踝关节跖屈力矩（比其他三款鞋大 1.21 Nm/kg，p < 0.001）和膝盖内旋力矩（比其他三款鞋大 0.09 Nm/kg，p = 0.012），而鞋顺应性/弹性导致额平面中更大的脚踝运动范围（比其他三款鞋大 1.4°，p < 0.001）。感知数据显示任何鞋子之间没有统计学上的显着差异。总之，篮球鞋中底的弹性插入物会产生生物力学负载效应。球员不受影响的感觉表明生物力学评估对于检查在侧切过程中给定的鞋子修改的影响的重要性。09 Nm/kg 比其他三款鞋大，p = 0.012），而鞋的柔顺性/弹性导致额平面中的脚踝运动范围更大（比其他三款鞋大 1.4°，p < 0.001）。感知数据显示任何鞋子之间没有统计学上的显着差异。总之，篮球鞋中底的弹性插入物会产生生物力学负载效应。球员不受影响的感觉表明生物力学评估对于检查在侧切过程中给定的鞋子修改的影响的重要性。09 Nm/kg 比其他三款鞋大，p = 0.012），而鞋的柔顺性/弹性导致额平面中的脚踝运动范围更大（比其他三款鞋大 1.4°，p < 0.001）。感知数据显示任何鞋子之间没有统计学上的显着差异。总之，篮球鞋中底的弹性插入物会产生生物力学负载效应。球员不受影响的感觉表明生物力学评估对于检查在侧切过程中给定的鞋子修改的影响的重要性。篮球鞋中底的弹性插入物会产生生物力学负载效应。球员不受影响的感觉表明生物力学评估对于检查在侧切过程中给定的鞋子修改的影响的重要性。篮球鞋中底的弹性插入物会产生生物力学负载效应。球员不受影响的感觉表明生物力学评估对于检查在侧切过程中给定的鞋子修改的影响的重要性。
