title: Comparison of offensive agility techniques in Australian Rules football.
abstract: Agility skill is important in Australian Rules football (ARF) as it enables an attacking player to successfully evade an opponent. To date, no research has examined offensive agility techniques in ARF. There were two purposes of this study: first, to compare the change of direction (COD) speed of three offensive agility techniques, and second, compare the reaction speed and accuracy when observing the same techniques from a defensive perspective. The techniques included the side-step, shuffle, and split-step. Seventeen players from an Australian Football League club were required to perform four trials of each technique. COD speed was expressed as a total time, and divided into entry, foot plant preparation, and exit time. In addition, nineteen players from the same club were assessed on a video-based reaction test. Players were required to respond by depressing a thumb switch to indicate whether the player on screen changed direction to the left or right. From an offensive perspective, the split-step foot plant preparation time (0.66 s) was significantly slower than both the side-step (0.7 s) and shuffle (0.75 s) (p<0.05), but there were no significant differences in entry and exit times between techniques. From a defensive perspective, the players were significantly slower and less accurate when reacting to the player in the video performing the split-step (0.19 s) and shuffle (0.15 s) compared to the side-step (0.12 s) (p<0.05). In a one-on-one situation in ARF, the split-step may be the most effective offensive technique. Not only was it slower and less accurate to react to, the exit speed following the change in direction was not significantly slower than the side-step. However, a performer would need to consider the cost of a slower foot plant preparation time versus the potential to deceive an opponent when under time stress.
