Soccer boots are produced with different stud patterns and configurations to provide players with extra traction on specific surface types to minimize slipping and improve player performance. Excessive traction, however, can lead to foot fixation injuries, particularly anterior cruciate ligament tears.
PURPOSE/HYPOTHESIS: The purpose of this study was to explore the translational traction properties of 5 different outsole configurations moving in 4 different directions across both natural grass and artificial grass (AG) playing surfaces. It was hypothesized that longer studs or studs with an asymmetric shape would yield a higher traction coefficient compared with the recommended stud configuration for the given playing surface.
Descriptive laboratory study.
A custom-built testing apparatus recorded the translational traction of 5 different soccer boots moving in an anterior, posterior, medial, or lateral direction on both natural grass and AG playing surfaces. A 3-way analysis of variance was performed to determine the effect of outsole configuration on the traction, and a post hoc Tukey analysis was performed to compare different outsole configurations with a control.
For the natural grass playing surface, the longer and asymmetric studs yielded a significantly higher ( < .05) traction coefficient on 75% of loading scenarios, while on AG, they yielded a significantly higher traction on 50% of loading scenarios.
Some soccer boots yielded higher traction values compared with the recommended configuration.
The results highlight the importance of boot selection on different playing surfaces. Higher traction values could increase the injury risk for players due to excessive traction and foot fixation.
足球鞋采用不同的鞋钉样式和配置，以便在特定地面类型上为球员提供额外的抓地力，从而尽量减少滑倒并提高球员表现。然而，过度的抓地力可能导致足部固定性损伤，尤其是前交叉韧带撕裂。
目的/假设：本研究的目的是探究5种不同鞋底配置在天然草皮和人造草皮（AG）比赛场地沿4个不同方向移动时的平移牵引力特性。研究假设是，与给定比赛场地推荐的鞋钉配置相比，更长的鞋钉或不对称形状的鞋钉将产生更高的牵引系数。
描述性实验室研究。
一个定制的测试装置记录了5种不同足球鞋在天然草皮和AG比赛场地沿前、后、内或外方向移动时的平移牵引力。进行了三因素方差分析以确定鞋底配置对牵引力的影响，并进行了事后Tukey分析以将不同的鞋底配置与对照组进行比较。
对于天然草皮比赛场地，在75%的加载情况下，更长和不对称的鞋钉产生的牵引系数显著更高（<.05），而在AG场地，在50%的加载情况下，它们产生的牵引力显著更高。
与推荐配置相比，一些足球鞋产生了更高的牵引力值。
结果突出了在不同比赛场地选择足球鞋的重要性。由于过度的抓地力和足部固定，更高的牵引力值可能会增加球员受伤的风险。
