Abstract

Representative learning design is a key feature of the theory of ecological dynamics, conceptualising how task constraints can be manipulated in training designs to help athletes self-regulate during their interactions with information-rich performance environments. Implementation of analytical methodologies can support representative designs of practice environments by practitioners recording how interacting constraints influence events, that emerge under performance conditions. To determine key task constraints on kicking skill performance, the extent to which interactions of constraints differ in prevalence and influence on kicking skills was investigated across competition tiers in Australian Football (AF). A data sample of kicks (n = 29,153) was collected during junior, state-level and national league matches. Key task constraints were recorded for each kick, with performance outcome recorded as effective or ineffective. Rules were based on frequency and strength of associations between constraints and kick outcomes, generated using the Apriori algorithm. Univariate analysis revealed that low kicking effectiveness was associated with physical pressure (37%), whereas high efficiency emerged when kicking to an open target (70%). Between-competition comparisons showed differences in constraint interactions through seven unique rules and differences in confidence levels in shared rules. Results showed how understanding of key constraints interactions, and prevalence during competitive performance, can be used to inform representative learning designs in athlete training programmes. Findings can be used to specify how the competitive performance environment differs between competition tiers, supporting the specification of information in training designs, representative of different performance levels.

摘要

代表性学习设计是生态动力学理论的一个关键特征,它概念化了在训练设计中如何操纵任务约束,以帮助运动员在与信息丰富的表现环境互动时进行自我调节。分析方法的实施可以支持从业者通过记录相互作用的约束如何影响在表现条件下出现的事件,来设计具有代表性的实践环境。为了确定对踢球技能表现的关键任务约束,研究了澳大利亚足球(AF)不同比赛级别中约束相互作用在流行程度和对踢球技能影响方面的差异。在青少年、州级和国家级联赛比赛中收集了一个踢球数据样本(n = 29,153)。记录每次踢球的关键任务约束,并将表现结果记录为有效或无效。规则基于使用Apriori算法生成的约束与踢球结果之间关联的频率和强度。单变量分析显示,低踢球效率与身体压力相关(37%),而向开阔目标踢球时效率较高(70%)。不同比赛之间的比较显示,通过七条独特规则,约束相互作用存在差异,共享规则的置信水平也存在差异。结果表明,对关键约束相互作用以及比赛表现期间流行程度的理解,如何可用于为运动员训练计划中的代表性学习设计提供信息。研究结果可用于明确不同比赛级别之间的比赛表现环境有何不同,支持训练设计中代表不同表现水平的信息的具体规定。
