A comparison of running and contact loads in U18 and U20 international rugby union competition
Résumé
Match performance in international rugby union INTRODUCTION Rugby Union is considered one of the most intense and physically demanding team sport games [1]. At elite senior standards, a comprehensive body of research has quantified the physical characteristics in match-play [2, 3, 4, 5, 6]. Analyses using micro-sensor technology such as Global Positioning Systems (GPS) show that the game is intermittent in nature [7]. Players perform frequent bouts of high-speed running and participate in intense physical collisions such as tackling and static actions including scrums, rucks and mauls [8]. In contrast, less information [9, 10] exists on the demands in younger elite players, notably in international competition and how these potentially evolve across different age categories. A comparison of U18 versus U20 amateur rugby union competition reported greater distances per minute
