### Performance  
Performance characteristics of the elite and sub-elite hurlers are shown in Table 1. At each respective level, there was no significant difference between individual positions for any of the performance characteristics; CMJ height (\(F_{4,127}\) = 0.275; \(p\) = 0.894; \(\eta^{2}\) = 0.009; _small_), CMJ PP (\(F_{4,127}\) = 2.832; \(p\) = 0.053; \(\eta^{2}\) = 0.082; _small_), CMJ RPP (\(F_{4,127}\) = 0.236; \(p\) = 0.917; \(\eta^{2}\) = 0.007; _small_), 5 m acceleration (\(F_{4,127}\) = 0.463; \(p\) = 0.763; \(\eta^{2}\) = 0.014; _small_), 10 m acceleration (\(F_{4,127}\) = 0.362; \(p\) = 0.835; \(\eta^{2}\) = 0.011; _small_), 20 m acceleration (\(F_{4,127}\) = 0.690; \(p\) = 0.601; \(\eta^{2}\) = 0.021; _small_) and Yo-Yo IRT1 (\(F_{4,127}\) = 2.383; \(p\) = 0.055; \(\eta^{2}\) = 0.070; _small_).  
When comparing performance characteristics at each position between levels of play, significant effects were determined for CMJ height (\(F_{1,127}\) = 140.683; \(p\) < 0.001; \(\eta^{2}\) = 0.526; _large_), CMJ PP (\(F_{1,127}\) = 139.914; \(p\) < 0.001; \(\eta^{2}\) = 0.524; _large_), CMJ RPP (\(F_{1,127}\) = 137.418; \(p\) < 0.001; \(\eta^{2}\) = 0.520; _large_), 5 m acceleration (\(F_{1,127}\) = 8.158; \(p\) = 0.005; \(\eta^{2}\) = 0.060; _small_), 10 m acceleration (\(F_{1,127}\) = 8.126; \(p\) = 0.005; \(\eta^{2}\) = 0.060; _small_), 20 m acceleration (\(F_{1,127}\) = 8.612; \(p\) = 0.011; \(\eta^{2}\) = 0.049; _small_) and Yo-Yo IRT1 (\(F_{1,127}\) = 79.592; \(p\) < 0.001; \(\eta^{2}\) = 0.385; _large_). Elite level players were shown to have significantly greater jump performance than their sub-elite counterparts across all positions; CMJ height [full-backs (\(p\) < 0.001; mean difference: 17.2 cm; \(\eta^{2}\) = 0.228, _medium_), half-backs (\(p\) < 0.001; mean difference: 12.3 cm; \(\eta^{2}\) = 0.160, _medium_), midfielders (\(p\) < 0.001; mean difference: 14.8 cm; \(\eta^{2}\) = 0.176, _medium_), half-forwards (\(p\) < 0.001; mean difference: 12.6 cm; \(\eta^{2}\) = 0.169, _medium_), and full-forwards (\(p\) < 0.001; mean difference: 13.6 cm; \(\eta^{2}\) = 0.173, _medium_), CMJ PP [full-backs (\(p\) < 0.001; mean difference: 1208 W; \(\eta^{2}\) = 0.219, _medium_), half-backs (\(p\) < 0.001; mean difference: 969 W; \(\eta^{2}\) = 0.186, _medium_), midfielders (\(p\) < 0.001; mean difference: 1007 W; \(\eta^{2}\) = 0.160, _medium_), half-forwards (\(p\) < 0.001; mean difference: 888 W; \(\eta^{2}\) = 0.163, _medium_) and full-forwards (\(p\) < 0.001; mean difference: 998 W; \(\eta^{2}\) = 0.177, _medium_), and CMJ RPP [full-backs (\(p\) < 0.001; mean difference: 12.6 W.kg\({}^{-1}\); \(\eta^{2}\) = 0.233, _medium_), half-backs (\(p\) < 0.001; mean difference: 10.1 W.kg\({}^{-1}\); 8.7 W.kg\({}^{-1}\); \(\eta^{2}\) = 0.156, _medium_), midfielders (\(p\) < 0.001; mean difference: 9.6 W.kg\({}^{-1}\); \(\eta^{2}\) = 0.185, \(\eta^{2}\) = 0.161, _medium_), half-forwards (\(p\) < 0.001; mean difference: 9.2 W.kg\({}^{-1}\); \(\eta^{2}\) = 0.156, _medium_). Finally, elite level players at all positions had significantly greater Yo-Yo IRT1 scores compared to their sub-elite counterparts [full-backs (\(p\) = 0.004; mean difference: 479 m; \(\eta^{2}\) = 0.063, _small_), half-backs (\(p\) < 0.001; mean difference: 554 m; \(\eta^{2}\) = 0.102, _small_), midfielders (\(p\) < 0.001; mean difference: 734 m; \(\eta^{2}\) = 0.134, _medium_), half-forwards (\(p\) < 0.001; mean difference: 615 m; \(\eta^{2}\) = 0.125, _medium_), and full-forwards (\(p\) < 0.001; mean difference: 705 m; \(\eta^{2}\) = 0.142, _medium_)] (Figure 1).
