Comparative analysis of winning and losing teams in rugby union

Abstract

Analyzing performance indicators in rugby is essential for improving training programs and team dynamics. A key direction is to compare these indicators between winning and losing teams in prestigious rugby tournaments to identify patterns and strategic insights that can enhance team performance. However, current research frequently examines isolated competitions and lacks thorough comparative analysis across different tournaments. This study aims to analyze and identify the differences between winning and losing men's rugby union teams across various competitions in 2023. This study analysed performance data from men's rugby competitions in 2023, encompassing matches from The Six Nations Championship, The Rugby Championship, and the Rugby World Cup. A total of 68 matches were examined, categorizing 47 matches from the Rugby World Cup and 21 from international competitions for comparative analysis. Data collection included 32 performance indicators for both winning and losing teams, analysed using statistical methods to identify significant differences. Comparative analysis of team performance indicators between the Rugby World Cup and international competitions, including The Six Nations Championship and The Rugby Championship, reveals significant differences. Winning teams in the Rugby World Cup scored significantly higher points on average (41.5 ± 13.2) compared to international competitions (32.8 ± 7.7), reflecting greater variability in performance at the World Cup. Conversely, losing teams in the Rugby World Cup averaged fewer points (13.2 ± 8.0) compared to international competitions (16.3 ± 6.9). These findings underscore distinct competitive levels across different rugby tournaments. The analysis revealed that in the World Cup, 18 indicators (56.3%) exhibit statistically significant differences between losing and winning teams, whereas the analysis of performances in international competitions identified only 4 (12.5%) statistically significant differences between losing and winning teams.
