This study aimed to understand the differences in technique between groups of rugby place kickers who achieve different performance outcomes. Thirty kickers were analysed using 3D motion capture and grouped as long (successful), wide-left or short (both less successful). The long kickers achieved a faster ball velocity than the short kickers by doing more positive hip flexor and knee extensor work. The long and wide-left kickers achieved comparable ball velocities, but used different strategies. The long kickers did more positive knee extensor work whereas the wide-left kickers did more positive hip flexor work, facilitated by a ‘tension arc’ achieved through pelvis-thorax rotation. Although the ‘tension arc’ may be beneficial for the generation of ball velocity magnitude, rugby place kicking coaches should be wary of its use due to its negative effect on accuracy.
