Abstract

Rugby union is a complex sport, involving the interaction of a number of behaviours which combine to form overall playing patterns. Previous research that has analysed key characteristics of scoring tries in rugby union has tended to report single variables in isolation from other related behaviours. The aim of this study was to identify patterns of play that lead to scoring tries in rugby union, with the purpose of demonstrating a holistic and process-oriented approach to analysing multiple performance variables simultaneously. Data related to the match context and events leading to tries were collected. K-modes cluster analysis was used to conduct a multidimensional data analysis and identify common playing patterns that preceded a try. It was found that plays following line-outs, scrums and kick receipts were highlighted as common approaches to scoring tries. In particular, the line-out–maul combination commencing from the attacking 22-m zone was found to be the most prominent pattern identified from the cluster analysis. Coaches and analysts can use the information presented by the cluster analysis as a framework to plan and implement effective set-play and open-play strategies.
