Outline of Final Research Achievements

We analyzed the soccer movement in actual game situations from uncalibrated video sequences. In the one-on-one defensive cutting action, smaller center of mass displacement was important for successful performance. Additionally, the normalized center of mass height at initial contact was correlated with the vertical center of mass displacement and hip flexion angle. Furthermore, soccer players moved the hip joint smoothly during pressing maneuvers. These results suggested that video sequences is valuable tool for evaluating field-based sports performance.
