Currently, there is a shortage of biomechanical data regarding acute skin injury mechanisms that are involved in player-surface contact in soccer on artificial turf. It is hypothesized that peak loads on the skin during the landing phase are an important factor in causing an acute skin injury.
Simultaneously, video analysis and load measurements using an in-ground force plate of the landing phase of a sliding tackle were recorded and correlated with observed clinical skin lesions.
Video analysis revealed two sliding techniques: a horizontal jump and a sliding-in technique. The first technique resulted in both significantly higher vertical and horizontal peak forces during impact on the knee (2.3±0.4 kN and 1.4±0.5 kN) and thigh (4.9±0.9 kN and 1.8±0.5 kN). In combination with the observed skin lesion areas, a combined normal-shear stress of at least 24 and 14 N.cm-2 induce abrasion injuries on dry artificial turf.
The findings of this study confirm that high peak stresses during the landing phase of a sliding is critical for inducing skin injuries on the knee and thigh. Reducing these peak shear stresses could be an important first step towards preventive measures.
目前，关于人造草皮足球运动中球员与场地接触所涉及的急性皮肤损伤机制的生物力学数据短缺。据推测，着陆阶段皮肤的峰值负荷是导致急性皮肤损伤的一个重要因素。
同时，记录了铲球着陆阶段的视频分析和使用地面测力板进行的负荷测量，并将其与观察到的临床皮肤损伤相关联。
视频分析揭示了两种滑动技术：水平跳跃和滑入技术。第一种技术在膝盖（2.3±0.4千牛和1.4±0.5千牛）和大腿（4.9±0.9千牛和1.8±0.5千牛）受到撞击时，垂直和水平峰值力均显著更高。结合观察到的皮肤损伤区域，至少24和14牛·厘米-2的组合正剪应力会在干燥的人造草皮上导致擦伤。
本研究结果证实，滑动着陆阶段的高峰值应力对于导致膝盖和大腿皮肤损伤至关重要。降低这些峰值剪应力可能是预防措施的重要第一步。
