Comparison of training activities and game demands in the Australian Football League

Abstract

his paper serves as a companion to our recent study of the movement patterns and game activities of players (from five different positions) during matches in the 2000 Australian Football League season. Using lapsed-time video analysis, the same individual players (n= 11) as filmed in matches were also monitored during 21 in-season, main training sessions conducted by their clubs in order to assess the degree to which training activities matched game demands. In general, the training sessions did not involve physical pressure; therefore there were very few contested marks and ground balls or tackles, shepherds and spoils, thereby not matching these game demands. Players typically had more possessions (kicks and handballs) at training than in games. They also spent a greater percentage of total time standing and less time walking at training than in games. Fast-running and sprinting efforts at training were almost all for durations of <6 secs, which matched game demands, as did changes of direction when sprinting, which were almost all in a 0-90 degrees arc. However, across all players filmed, high intensity (fast-running and sprinting) movements were not performed as frequently at training (one every 76 secs) as in games (one every 51 secs). Therefore, while some game demands were adequately replicated at training, others were not closely simulated, suggesting that, after careful interpretation of these results, some improvements in training practices could be made.
