abstract="Understanding the most demanding passages of European Super League competition can optimise training prescription. We established positional and match half differences in peak relative distances (m·min<sup>-1</sup>) across durations, and the number of collisions, high-speed- and very-high-speed-distance completed in the peak 10 min period. Moving-averages (10 s, 30 s, 1 min, 5 min, 10 min) of instantaneous speed (m·s<sup>-1</sup>) were calculated from 25 professional rugby league players during 25 matches via microtechnology. Maximal m·min<sup>-1</sup> was taken for each duration for each half. Concurrently, collisions (n), high-speed- (5 to 7 m·s<sup>-1</sup>; m) and very-high-speed-distance (> 7 m·s<sup>-1</sup>; m) were coded during each peak 10 min. Mixed-effects models determined differences between positions and halves. Aside from peak 10 s, trivial differences were observed in peak m·min<sup>-1</sup> between positions or halves across durations. During peak 10 min periods, adjustables, full- and outside-backs ran more at high-speed and very-high-speed whilst middle- and edge-forwards completed more collisions. Peak m·min<sup>-1</sup> is similar between positional groups across a range of durations and are maintained between halves of the match. Practitioners should consider that whilst the overall peak locomotor &quot;intensity&quot; is similar, how they achieve this differs between positions with forwards also exposed to additional collision bouts.<p /> <p>Language: en</p>",
