  1. 1. TEAM RANK AND ATTACKING PHASES IN RUGBY LEAGUE Rachael Wiseman Email: u3017119@uni.canberra.edu.au INTRODUCTION RESULTS CONCLUSION The attacking phase in rugby league is a key aspect of every Analysis showed that there was an association between team rank The key finding of this study was that teams lower on the NRL results game. There are a number of components that are thought to and the number of passes in a phase (χ2 (6) = 69.77, p= <.001). ladder were inclined to pass less and tried to run the ball down the make up a successful attacking phase. These include the field • 91.4% (SR= 2.5) of teams ranked 13-16 on the results ladder centre of the field. Whereas teams that were ranked higher on the ladder position, quality of passes and number of passes made in each were associated with passing less than twice in a phase passed ball more and also tended to pass the ball out wider. Teams that phase. Recently there has been a great deal of research • 25.3 % (SR = 4.3) of teams ranked 5-8 were associated with passed more than five times in a phase were more likely to score a try regarding attacking and defensive plays in rugby league (1, 2). passing the ball 3-4 times in a phase. although it was also noted that when passing the ball more frequently, These studies have focused on using time motion analysis. • 7.1% (SR=-4.2) of teams placed 13-16 on the ladder were there was a higher incidence of errors. Furthermore, there was a trend With the purpose to examine time spent in attack and defence less likely to use 3-4 passes in a phase. indicating that teams that gained more than 21metres in a phase were as well as the speeds reached by players (1, 2).

The aim of the project was to examine if there is the relationship The results indicated that there was trend between errors and the This study can be used to enable coaches to focus more on increasing between team rank and the number of passes and metres number of passes made (χ2 (2) = 3.504, p= 0.173). the number of passes made, while maintaining quality passes, as well as gained in attack. The objectives of this study were to determine • 14.3% (SR=1.7) of errors were related with than more than 5 creating more space and consequently more metres gained in a single if: passes in a phase of play. phase. Furthermore, the study provides coaches with information • The number of passes made and field position vary necessary in developing better patterns to play in rugby league, between teams ranked on the top and bottom of the ladder. Results indicated that there was a positive trend (SR≥2.0) essentially improving a team’s overall performance. An Independent Samples t Test was conducted to • The number of passes in a phase varies between team rank. between scoring a try and the number of passes made, however it compare the number of metres gained when a try • The number of metres gained in a phase influences if a try was statistically insignificant (χ2 (2) =5.276, p=0.072). was or was not scored.
