Accurate goal-kicking is important to a team's success in Australian Football (AF). However,
it remains a largely unexplored area in sport biomechanics. This study examined technical
aspects of goal-kicking accuracy using an inertial measurement system (IMS). Two junior AF
players performed 15x20m goal-kicks in the field. Kinematics were measured using the

Abstract
Accurate goal-kicking is important to a team’s success in Australian Football (AF). However, it remains a largely unexplored area in sport biomechanics. This study examined technical aspects of goal-kicking accuracy using an inertial measurement system (IMS). Two junior AF players performed 15x20m goal-kicks in the field. Kinematics were measured using the Xsens MVN link IMS (240Hz). Results showed that both players had greater support leg (p< 0.04; d> 1.0) and kick leg (d> 1.0) knee flexion during accurate goal-kicks. Individual differences were reported for footspeed and shank angular velocities for accurate goal-kicks. These individual differences highlight the need to conduct an individual-based analysis in goal-kicking research.
