Team performance indicators which differentiate between winning and losing in elite Gaelic football

The objective of this study was to identify performance indicators which differentiated between winning and losing elite Gaelic football teams. Eighty three technical and tactical performance variables were measured in 13 teams during 26 league and championship games throughout 2014-15. Univariate analysis of full-games revealed that winners achieved a significantly higher total score, number of scores, shots, points, points from play and goals, resulting in superior shot efficiency, average attack per score, and scores per 10 possessions. Winners gained significantly more turnovers and completed significantly less unsuccessful hand passes. Winners also performed significantly less kick outs, resulting in fewer successful kick outs and successful dead ball kick passes overall. A principal component analysis, conducted on 18 variables produced 4 components, which explained 81.9% of the variance. Both logistic regression (8.00, χ 2 (1) = 16.00, p < 0.001) and discriminant analysis (Ʌ = 0.53, χ 2 (1) = 13.77, p < 0.001) revealed that 1 component; defensive counterattacking, significantly contributed to outcome and differentiated winners from losers with a cross-validation accuracy of 87.5%. Coaches can use this information to organise their defensive system to generate opposition turnovers and also incorporate sufficient flexibility to facilitate effective transitions to exploit their own offensive counterattacking opportunities
