Novel component variables can be used to distinguish between winning and losing across match periods in elite Gaelic football

This study examined whether team performance indicators could be used to differentiate winners from losers across specific match periods in 26 Gaelic football games. A principal component analysis, conducted on either 25 (halves) or 27 (quarters) variables, produced 6 components, which explained 83.5% and 81.0% of the variance for halves and quarters, respectively. Generalised estimating equation models were used to identify derived components which differentiated winners from losers across specific periods. In winning halves, 4 components were significant; midfield counterattacking (p = 0.008), possession (p = 0.001), low press efficiency (p = 0.032) and tackle pressure (p = 0.023). Possession (p = 0.007) and tackle pressure (p = 0.014) contributed significantly more to winning in the second compared to the first half. In winning quarters, 4 components were also significant; midfield counterattacking (p = 0.000), possession (p = 0.000), offensive dead ball efficiency (p = 0.029) and high press efficiency (p = 0.034). High press efficiency (p = 0.000) and midfield counterattacking (p = 0.021) contributed significantly more to winning in quarters 1 and 2, respectively, in comparison to quarter 4. These results can be used by coaches to develop tactical strategies and establish performance targets for specific match periods.
