Agility is an important skill for both attackers and defenders in invasion sports such as codes of football. On the sporting field, agility requires reacting to a stimulus, often presented by an opponent's movement, before a change of direction or speed. There is a plethora of research that examines the movement component of agility in isolation, which is described as change-of-direction (COD) ability, and this is thought to underpin agility performance. This opinion article proposes that COD ability should not be researched as the only or primary outcome measure when the objective is to inform agility performance in invasion sports. It is argued that pre-planned COD movements and tests lack ecological validity because they lack perception-action coupling and involve movement out of context from the game. The movement techniques and strength qualities required for the performance of COD tests can be quite different to those required for agility. It is suggested that COD tests can be applied to sports that involve pre-planned COD movements, but researchers should endeavour to use agility tests when studying invasion sports. Some new methods for assessing one-on-one agility contests are reported as potentially valuable for future research, and examples of research questions are provided.
在诸如各类足球运动等侵入性运动中，敏捷性对于进攻者和防守者而言都是一项重要技能。在运动场上，敏捷性要求在改变方向或速度之前对通常由对手动作呈现的刺激做出反应。有大量研究单独考察敏捷性的动作成分，即变向（COD）能力，并且认为这是敏捷性表现的基础。这篇观点文章提出，当目标是为侵入性运动中的敏捷性表现提供信息时，COD能力不应作为唯一或主要的结果指标来研究。有人认为，预先计划好的COD动作和测试缺乏生态效度，因为它们缺乏感知 - 动作耦合，并且涉及脱离比赛情境的动作。COD测试所需要的动作技术和力量素质可能与敏捷性所需的大不相同。建议COD测试可应用于涉及预先计划好的COD动作的运动，但研究人员在研究侵入性运动时应尽量使用敏捷性测试。报告了一些评估一对一敏捷性对抗的新方法，认为它们对未来研究可能具有价值，并提供了研究问题的示例。
