The aim of this study was to compare ankle and knee joint moments observed when playing on sport surfaces that slide slightly relative to the ground with the moments observed when playing on conventional sport surfaces. Three-dimensional resultant internal joint moments and kinematic characteristics of the lower extremity were quantified for 21 university basketball players when performing v-cut and side-shuffle tasks on three types of sliding surface (interlocking tiles) and on two types of conventional surface (maple wood and rolled vinyl). Translational and rotational friction between the five test surfaces and a test shoe were also quantified. The five sport surfaces moved horizontally between 0.2 and 1.6 mm during the landing phase of the two tasks. The medio-lateral ground reaction forces were lowest for the surfaces with the highest horizontal movement. Resultant ankle joint moments were lower and resultant knee moments were higher on the sliding surfaces than the conventional surfaces. Sport surfaces that allow a few millimetres of horizontal movement during ground contact may reduce joint loading at the ankle joint, but increase joint loading at the knee joint, when compared with conventional sport surfaces, and thus may influence the prevalence of knee injuries.
本研究的目的是比较在相对于地面有轻微滑动的运动表面上进行运动时观察到的踝关节和膝关节力矩，与在传统运动表面上进行运动时观察到的力矩。对21名大学篮球运动员在三种类型的滑动表面（联锁瓷砖）和两种类型的传统表面（枫木和卷材乙烯基）上执行变向切入和侧滑任务时的三维合成内部关节力矩和下肢运动学特征进行了量化。还对五个测试表面与一只测试鞋之间的平移摩擦和旋转摩擦进行了量化。在两项任务的着地阶段，五个运动表面在水平方向上移动了0.2至1.6毫米。水平移动最大的表面的内外侧地面反作用力最低。与传统表面相比，滑动表面上的合成踝关节力矩较低，而合成膝关节力矩较高。与传统运动表面相比，在地面接触期间允许几毫米水平移动的运动表面可能会减少踝关节的关节负荷，但会增加膝关节的关节负荷，因此可能会影响膝关节损伤的发生率。
