Abstract
The purpose of this study was to examine differences in physical performance and game-specific skills between elite and semi-elite rugby league players during match-play. Time–motion analysis was used to determine physical and game-specific skill match demands in 17 elite and 22 semi-elite rugby league players. Physical performance (time, intensity of exercise, frequency, repeated-sprint ability, and speed measures) and game-specific skill measures (ball carries, supports, ball touches, play-the-balls, and tackles) were recorded per minute of playing time. The main findings were that total intensity (elite: 108.9 ± 10.6 m · min−1; semi-elite: 102.3 ± 9.7 m · min−1), high-intensity exercise (elite: 36.7 ± 9.8 m · min−1; semi-elite: 29.6 ± 7.8 m · min−1), mean playing speed (elite: 6.6 ± 0.6 km · h−1; semi-elite: 6.2 ± 0.6 km · h−1), and support play (elite: 0.29 ± 0.16 · min−1; semi-elite: 0.15 ± 0.09 · min−1) were all higher during first-half match-play in the elite than semi-elite players (P < 0.01). The elite players experienced decrements in most physical performance measures during the second-half of match-play (P < 0.01), which was not evident in the semi-elite players (P > 0.01). There were no differences in most physical performance and game-specific skill measures for the match between the two playing standards. These results show that while the two standards of competition have similar game-specific skills and physical demands during a match, there is variation within a match according to standard. Specifically, the higher physical demands placed on elite players during the first half could result in the earlier onset of physical fatigue towards the end of a match. Verf.-Referat
