What is it about?
The purpose of this study was to investigate differences in DVJ first and second landings based on LESS score analysis among a cohort of female athletes who specialize in either gymnastics or softball. Biomechanical analysis of the DVJ offers potential study of 2 separate landing types: the drop from the box height as well as the landing after the vertical jump. The first landing is a planned activity during which the athlete is focused on the landing in order to prep for the subsequent jump. The second landing represents a time which the athlete is not focused on a subsequent task. Therefore the comparisons of landing mechanics for both landings provides us insight into 2 different types of landings in lone activity.

Why is it important?
Summary of the paper's conclusion: "Study findings demonstrate that the LESS is effective in detecting differences between the first and second landing biomechanics. Type of sport-specific landing training might influence LESS scores and associated landing biomechanics.
Perspectives
Assessment of both landings during the DVJ task may provide a more comprehensive view of an athlete’s neuromuscular control. Understanding the influences of sports specific training on assessment is important for better application of appropriate screening tools as well as understanding injury risk during play. The second landing may be more effective than the first landing of the DJT in identifying those at risk for injury. Future study is needed in this concept whether using the LESS system or 3D biomechanics.
