目的网球运动员因运动场地摩擦特性的变化而采用的不同策略可能会影响损伤的发生率。据报道，在允许滑动的表面上受伤的风险较低。本研究的目的是在硬地和人造粘土在两个表面特定的shoes.MethodsTwo网球表面进行了比较：人造粘土和人造丙烯酸硬地网球特定的动作过程中，在鞋内的压力。参与者在每个表面上穿着两双不同的球场专用鞋。七名（五名男性，两名女性）竞技网球运动员表演了三个动作-开放式站姿，跳跃式（纳入训练）和侧跳。在鞋足底压力分布记录使用Pedar（小说，慕尼黑）鞋垫system. Results显着较低的平均值和峰值压力，测量在侧跳和运行在粘土上的植物相比，硬地。在人造粘土上运行无菌装置的特征在于比在丙烯酸上更长的步骤持续时间和更大数量的卸载事件。鞋类并没有影响peakpressure.ConclusionsA表面的变化有更大的影响足底压力比鞋的变化。硬地球场上的更高压力支持过度使用伤害水平增加的关联。在粘土上，限制高压区域和较长的制动步骤可以通过防止粘滞来促进滑动。卸载插曲也可能是战略的一部分，旨在在粘土上滑动。这些差异与理解损伤的表面特异性机制有关。
PurposeThe different strategies employed by tennis players as a result of changes in friction properties of the playing surface are likely to influence injury incidence. Lower risk of injuries on surfaces that allow sliding has been reported. The aim of the present study was to characterise in-shoe pressure during tennis specific movements performed on a hard court and artificial clay in two surface-specific shoes.MethodsTwo tennis surfaces were compared: artificial clay and cushioned acrylic hard court. Participants wore two different pairs of court-specific shoes on each surface. Seven (five males, two females) competitive tennis players performed three movements - open stance forehand, forehand plant (incorporated into a drill) and side jump. In-shoe plantar pressure distribution was recorded using the Pedar (Novel, Munich) insole system.ResultsSignificantly lower mean and peak pressure were measured during the side jump and running forehand plant on clay compared to hard court. Running forehand plant on artificial clay was characterised by a longer step duration and larger number of unloading episodes than on acrylic. Footwear did not influence peak pressures.ConclusionsA change in surface has a greater effect on plantar pressures than a change in shoe. The higher pressures on a hard court support an association for increased levels of overuse injuries. On clay, limiting areas of high pressure and a longer braking step could facilitate sliding by preventing sticking. Unloading episodes could also be part of the strategy aiming at sliding on clay. These differences are relevant to understand surface-specific mechanisms of injuries.
