THE SAGITTAL-PLANE LANDING BIOMECHANICS WITH MOVING FORWARD
Keywords: drop landing, trunk, lower extremity, kinematics, ground reaction force
AbstractThe purpose of this study was to identify the difference of vertical ground reaction force and lower extremity and trunk kinematics in landing with moving forward. Ten healthy female subjects participated in this study. They performed four different single-leg landing tasks with dominant leg. The distances between 30 cm height box and force platform were set 0, 15, 30, 45 cm, respectively. A motion analysis system was used to obtain ground reaction force and the lower extremity and the trunk kinematics. There were significant differences in the only hip joint kinematics, such as the hip flexion angle at initial contact and the peak hip flexion angle during absorption phase of landing. Hip flexion angle showed the increase with the increase of forward moving distance. This result suggested that the landing with moving forward would change only hip joint kinematics.
