Background: The use of Global Positioning Systems (GPS) has proved useful in describing positional differences in both rugby union (Cunniffe et al. 2009) and rugby league (Austin and Kelly 2012).
Purpose: The aim of this study was to (a) examine positional comparisons of locomotive and impact data of International Rugby League players and (b) determine if there were any differences across playing level (senior vs. academy).
