Positional tackle and collision rates in Super Rugby

Abstract

The aim of this study was to evaluate differences between playing positions regarding tackle and collision rates in a rugby game, and to determine the collision rates of individual playing positions in professional rugby union. Data from 30 matches (both teams involved) during the 2013 Super Rugby Season were captured and supplied by the Cheetahs Super Rugby Franchise, using the Verusco TryMaker Pro. Significant differences were found between positional groups regarding tackle rates. However, the front row players and second row players did not differ significantly (positions 1, 2, or 3 vs positions 4, or 5; p=0.0715 to p=0.6324). Within a positional group, only the difference between the inside centre and the other inside backs was significant (9 vs 12, p=0.0029; 10 vs 12, p=0.0045; 12 vs 13, p=0.0100). No significant differences were observed between second row players and the eighthman (4 vs 8, p=0.4183 and 5 vs 8, p=0.6863), although significant differences were found between second row players and the rest of the loose forwards (6 and 7). A significant difference (p≤0.05) occurred between all forwards and backs when collision rates were compared. The findings revealed significant inter-positional differences in tackling and collision rates within the same positional group.
