In the Australian Football League (AFL), specific game movements and activities have not been studied since the 1970s and 1980s and the game is now much faster than it was 20-30 years ago. Using lapsed-time video analysis, AFL players from five different positions (full forward/full back, centre half forward/centre half back, small forward/small back, mid fielders and ruckmen) had their movement patterns (stand, walk, jog, fast-run, sprint, change of direction) and game activities (possessions, ruck duels, ground ball contests, shepherds, spoils, bumps and tackles) recorded in two games each in the 2000 season. A descriptive analysis of the results was undertaken. The main findings were: full forward/full back were most different from the other positions, as they were seen to stand more and jog and fast-run less: ruckmen and midfielders were involved in more game activities than the other positions; for all positions, there were more than 150 high intensity movements (fast-run plus sprint) in the game, but these accounted for only 4-6% of total movement time: virtually all of the high intensity movements lasted for <6 secs; more than half of all sprints involved at least one change of direction, mostly within the 0-90 degrees arc (left or right) and all ground ball contests took <6 secs, with midfielders having 2-3 times as many as the other positions. Improvements in specific pre-season and in-season training practices for different positions should be possible after careful interpretation of these findings.
自20世纪70年代和80年代以来，澳大利亚足球联赛（AFL）中特定的比赛动作和活动就未被研究过，而如今比赛的节奏比20到30年前快得多。通过使用慢动作视频分析，对来自五个不同位置（全前锋/全后卫、中卫/中后卫、小前锋/小后卫、中场球员和中锋）的AFL球员在2000赛季的两场比赛中的运动模式（站立、行走、慢跑、快跑、冲刺、变向）和比赛活动（控球、争球、地面球争夺、护球、破坏球、碰撞和铲球）进行了记录。对结果进行了描述性分析。主要发现如下：全前锋/全后卫与其他位置差异最大，因为他们站立的时间更多，慢跑和快跑的时间更少；中锋和中场球员参与的比赛活动比其他位置更多；对于所有位置，比赛中高强度动作（快跑加冲刺）超过150次，但这些仅占总运动时间的4%至6%；几乎所有高强度动作持续时间都小于6秒；超过一半的冲刺至少涉及一次变向，大多在0至90度弧度内（向左或向右），并且所有地面球争夺时间都小于6秒，中场球员的争夺次数是其他位置的2至3倍。在仔细解读这些发现之后，针对不同位置改进特定的季前和赛季中的训练方法应该是可行的。
