Abstract: The aim of this study was to analysis tackles within 2 levels of rugby union. Ten Rugby World Cup matches and 10 Principality Welsh Premiership matches were analysed. The 125.8±40.6 tackles performed in World Cup matches was significantly greater than the 88.1±14.0 performed in Welsh Premier matches (p < 0.001). Mann-Whitney U tests were used to compare the two different levels of play while Wilcoxon signed ranks tests were used to compare performance of chop and other types of tackle. Furthermore, the 31.3±14.2% of tackles in World Cup matches that were chop tackles was significantly greater than the 22.6±8.5% in Welsh Premier matches (p = 0.038). The percentage of chop tackles that led to a turnover was significantly greater than the percentage of other types of turnover in both World Cup matches (p = 0.003) and Welsh Premier matches (p = 0.003). However the percentage of chop tackles that were unsuccessful was also significantly greater than the percentage of other types of turnover in both World Cup matches (p = 0.023) and Welsh Premier matches (p < 0.001). Therefore, the chop tackle is an example of a technique with high risk but also high opportunity of success.
