Positional group significantly influences the offensive and defensive skill involvements of junior representative rugby league players during match play

摘要

This study examined the skill involvements of three positional groups across a junior representative rugby league season. Data were collected from 45 rugby league players (mean +/- SD; age = 16.5 +/- 1.0 years) currently participating in the Harold Matthews and SG Ball Cup. Players were subdivided into hit-up forwards, adjustables and outside backs. The frequency (n . min(-1)) of offensive, defensive and overall involvements was coded for each group using a notation system and a practical coach skill analysis tool. Multivariate analysis of variance (MANOVA) revealed a significant effect of playing position on skill involvements (F = 9.06; P < 0.001; ES = 0.41). Hit-up forwards performed a significantly greater frequency of offensive (0.31 +/- 0.10), defensive (0.42 +/- 0.15) and overall involvements (0.74 +/- 0.19) when compared to adjustables (0.20 +/- 0.08, 0.28 +/- 0.08 and 0.52 +/- 0.15, respectively) and outside backs (0.20 +/- 0.12, 0.11 +/- 0.07 and +/- 0.31 +/- 0.17, respectively). Further, adjustables performed a significantly greater number of defensive (0.28 +/- 0.08) and overall involvements (0.52 +/- 0.15) when compared to outside backs (0.11 +/- 0.07 and 0.31 +/- 0.17, respectively). The findings of this study suggest that it is important to consider a junior player's positional group when analysing their skill involvements. Information gained from this study could assist in the design of specific training methodologies for junior rugby league players in high-level talent development programmes.
