The purpose of this study was to determine the dynamic contributions of joint torques to the generation of kicking foot speed in rugby place kicking. Motion capture and ground reaction force data were recorded from three Japanese rugby players, who were instructed to kick as far and as straight as possible. Each kicker‘s whole body was modelled as a system of 15 rigid-linked segments. The major contributors were calculated using equations of whole-body motion, including consideration of the generating factors of the motion-dependent terms. The flexion torque at the kicking leg hip joint was found to be the largest contributor for all kickers; exerting large flexion torques at the kicking hip joint throughout the final aerial phase of the approach and the subsequent kicking action appears crucial for obtaining a large kicking foot speed.
