We analyzed the kinematics and kinetics of vertical drop jump landing in a group of 85 (20 females) elite youth soccer players (U10-U11 and U17). Peak knee flexion and knee varus increased in male players as a function of age; normalized peak vertical ground reaction forces decreased with age and in female players. Preliminary data can be used to build reference tables for this specific population and can help to correct dangerous landing strategies, and to keep each player’s development monitored. We also suggest that education of safe landing technique would prevent dangerous knee postures.
