This study focused on two-dimensional shock attenuation properties of sports surfaces. Shock attenuation tests and friction tests are generally performed to access 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 cushioning characteristics of sport surfaces in previous studies. In this study, the various cushioned and non-cushioned impact tests with various impact angles were examined to calculate the VFR (Vertical Force Reduction) and HFR (Horizontal Force Reduction) values without slippery conditions.
