The purpose of this study was to determine the effects of training change-of-direction speed and small-sided games on performance in the Planned-AFL agility test and reactive agility. Twenty-five elite-standard U-18 Australian Rules football players were randomly allocated either to a change-of-direction group or a small-sided games group. Players participated in one or two 15-min sessions per week with 11 sessions conducted over a 7-week period during the season. Tests conducted immediately before and after the training period included the Planned-AFL agility test and a video-based reactive agility test specific to Australian Rules football. The reactive agility test variables were total time, decision time and movement response time. The small-sided games group improved total time (P = 0.008, effect size = 0.93), which was entirely attributable to a very large reduction in decision time (P < 0.001, effect size = 2.32). Small-sided games produced a trivial change in movement response time as well as in the Planned-AFL agility test (P > 0.05). The change-of-direction training produced small to trivial changes in all of the test variables (P > 0.05, effect size = 0-0.2). The results suggest that small-sided games improve agility performance by enhancing the speed of decision-making rather than movement speed. The change-of-direction training was not effective for developing either change-of-direction speed as measured by the Planned-AFL test or reactive agility.
本研究的目的是确定变向速度训练和小型比赛对计划-AFL敏捷性测试和反应敏捷性表现的影响。25名精英水平的18岁以下澳大利亚式橄榄球运动员被随机分配到变向训练组或小型比赛组。球员们每周参加一到两次15分钟的训练课，在赛季的7周时间内共进行11次训练课。在训练期前后立即进行的测试包括计划-AFL敏捷性测试和一项基于视频的、针对澳大利亚式橄榄球的反应敏捷性测试。反应敏捷性测试变量包括总时间、决策时间和动作反应时间。小型比赛组的总时间有所改善（P = 0.008，效应量 = 0.93），这完全归因于决策时间的大幅减少（P < 0.001，效应量 = 2.32）。小型比赛在动作反应时间以及计划-AFL敏捷性测试中产生了微小变化（P > 0.05）。变向训练在所有测试变量中产生了小到微小的变化（P > 0.05，效应量 = 0 - 0.2）。结果表明，小型比赛通过提高决策速度而非动作速度来改善敏捷性表现。变向训练对于通过计划-AFL测试测量的变向速度或反应敏捷性的发展均无效。
