Description

A drop jump and landing, followed by another maximal jump and landing, has been used when assessing injury risk utilizing the Landing Error Scoring System (LESS). Vertical ground reaction force (vGRF) and knee excursion are also commonly analyzed during a drop vertical jump. Previous studies have assessed initial drop vertical jump landing mechanics without assessing the second landing from the subsequent vertical jump. Additionally, analyzing landing mechanics based on subject jump height has not been examined for either landing 1 (L1) or landing (L2). The purpose of this study was to investigate whether there was a difference in LESS scores, vGRF, and knee excursion between the first and second landings of the drop vertical jump in all subjects and when divided into subgroups based on jump height.
