This study compared reactive agility between higher-standard (n = 14) and lower-standard (n = 14) Australian footballers using a reactive agility test incorporating a life-size video image of another player changing direction, including and excluding a feint. Mean agility time in the feint trials was 34% (509 ± 243 ms; p < 0.001; effect size 3.06) longer than non-feint trials. In higher-standard players, agility time was shorter than for lower-standard players in both feint (114 ± 140 ms; p = 0.18; effect size 0.52; likely beneficial) and non-feint (32 ± 44 ms; p = 0.22; effect size 0.47; possibly beneficial) trials. Additionally, the inclusion of a feint resulted in movement time increasing over three times more in the lower-standard group (197 ± 91 ms; p = 0.001; effect size 1.07; almost certainly detrimental) than the higher-standard group (62 ± 86 ms; p = 0.23; effect size 0.66; likely detrimental). There were weak correlations between the feint and non-feint trials (r = -0.13-0.14; p > 0.05), suggesting that reactive agility involving a feint is a unique skill. Also, higher-standard players are more agile than their lower-standard peers, whose movement speed deteriorates more as task complexity increases with the inclusion of a feint. These results support the need for specific training in multi-turn reactive agility tasks.
本研究比较了具有较高标准（n = 14）和较低标准（n = 14）的澳大利亚足球运动员在包含另一名球员改变方向的真人大小视频图像的反应敏捷性测试中的反应敏捷性，包括和不包括假动作。假动作试验中的敏捷时间平均长 34%（509 ± 243 毫秒；p < 0.001；效应量 3.06）。在较高标准的球员中，假动作（114 ± 140 毫秒；p = 0.18；效应量 0.52；可能有益）和非假动作（32 ± 44 毫秒；p = 0.22；效应量 0.47；可能有益）试验中，敏捷时间都比低标准球员短。此外，在低标准组中，假动作的加入导致运动时间增加了三倍以上（197 ± 91 毫秒；p = 0.001；效应量 1.07；几乎肯定有害），而在高标准组中，运动时间仅增加了 62 ± 86 毫秒（p = 0.23；效应量 0.66；可能有害）。假动作和非假动作试验之间的相关性较弱（r = -0.13-0.14；p > 0.05），表明涉及假动作的反应敏捷性是一种独特的技能。此外，高标准的球员比他们低标准的同行更敏捷，随着任务复杂性的增加，假动作的加入使他们的运动速度下降得更厉害。这些结果支持在多回合反应敏捷性任务中进行特定训练的需要。
