Biomechanics of goal-kicking in rugby league

WithK. BALL, D. TALBERT AND S. TAYLOR 47

In spite of the importance of goal-kicking, there is little scientific work examining goal-kicks. In the only technical analysis of either rugby code, Bezodis et al. (2007) examined five university first team rugby kickers performing kicks for accuracy and distance. Three dimensional data were collected for the full body during each kick (VICON, 120Hz). The authors reported angular momentum of the non-kick side arm was greater in the more accurate kickers in the anterior-posterior axis (axis direction in the kick direction) and about the longitudinal axis (i.e. vertical line through the trunk). The authors suggested that this was due to better control of whole body momentum and for altered trunk positioning. Bezodis et al. (2007) also reported more skilled kickers adopted a ball contact position where the trunk leaned towards the kick side while less skilled kickers leaned away from the kick.
