Summary:This study focused on two-dimensional deformation behavior of sports surfaces. Shock attenuation tests and friction tests are generally performed to assess the vertical and horizontal properties of the sports surfaces, respectively. Although the diagonal impacts are often observed in human activities, these tests treat only the vertical impact test. Therefore two-dimensional impact test device were developed for examining the two-dimensional properties of sport surfaces. In previous studies, we evaluated two-dimensional shock attenuation properties of sports surfaces with the VFR (Vertical Force Reduction) and HFR (Horizontal Force Reduction) values. Additionally, we evaluated vertical and horizontal displacement by two-dimensional impact tests with high-speed video analysis in this study.
