The aim of the present study was to evaluate, during ordinary training, the lower limb kinematics in young football players, and to verify if the kinematic patterns are influenced by coordinative motor abilities. Fourteen healthy players (10y ± 2m) were enrolled. Each player performed two activities: a pre-defined path with typical movements of football training and matches; the Harre test to evaluated children’s coordinative motor ability. Wearable inertial sensors were used to assess lower limb joint kinematics and accelerations. Based on Harre test, players were divided into two groups, more coordinated and less coordinated. During all tasks performed, less coordinated players showed stiffer kinematic strategies and greater limb asymmetry, which are potentially risky patterns for non-contact (e.g. Anterior Cruciate Ligament) injury. Quantitative analysis on the field could contribute to deepening the biomechanical understanding of players’ motion and injury risk.
