Augmented feedback supplements or replaces task-intrinsic feedback and is common in team sports, however, no studies have reported on augmented feedback provision in professional Australian Football (AF) practice. This study investigated the effects of practice characteristics (feedback intervention frequency, practice time, practice type, season phase, practice activity form and competitive match result) on the duration of feedback provided by professional AF coaches. Two linear mixed-effects models were constructed. The first examined the collective associations between these practice characteristics and feedback durations while the second model investigated the associations between the same practice characteristics and previous match result. Results showed the feedback intervention frequency, practice time and a practice time*feedback intervention frequency interaction explained 65% of feedback duration whenever feedback was provided. Additionally, practice time, feedback intervention frequency, a practice time*match result interaction and a match result*feedback intervention frequency interaction explained 99% of feedback duration in-season. Important factors that were hypothesised to affect feedback durations in AF such as practice type, practice activity form or season phase did not contribute any explanatory power. This study provides information on how professional AF coaches provide augmented feedback in-situ and provides opportunities for skill acquisition specialists to aid coaches when delivering augmented feedback.

增强反馈补充或替代了任务内在反馈，在团队运动中很常见，但是，没有研究报告在职业澳大利亚足球 (AF) 实践中提供增强反馈。本研究调查了练习特征（反馈干预频率、练习时间、练习类型、赛季阶段、练习活动形式和竞技比赛结果）对专业AF教练提供反馈时长的影响。构建了两个线性混合效应模型。第一个模型检查了这些练习特征与反馈持续时间之间的集体关联，而第二个模型研究了相同练习特征与之前比赛结果之间的关联。结果显示反馈干预频率，练习时间和练习时间*反馈干预频率交互解释了提供反馈时 65% 的反馈持续时间。此外，练习时间、反馈干预频率、练习时间*比赛结果交互和比赛结果*反馈干预频率交互解释了99%的赛季反馈持续时间。假设影响 AF 反馈持续时间的重要因素，如练习类型、练习活动形式或季节阶段，没有任何解释力。这项研究提供了有关专业 AF 教练如何提供增强反馈的信息 练习时间*比赛结果交互和比赛结果*反馈干预频率交互解释了99%的赛季反馈持续时间。假设影响 AF 反馈持续时间的重要因素，如练习类型、练习活动形式或季节阶段，没有任何解释力。这项研究提供了有关专业 AF 教练如何提供增强反馈的信息 练习时间*比赛结果交互和比赛结果*反馈干预频率交互解释了99%的赛季反馈持续时间。假设影响 AF 反馈持续时间的重要因素，如练习类型、练习活动形式或季节阶段，没有任何解释力。这项研究提供了有关专业 AF 教练如何提供增强反馈的信息现场并为技能获取专家提供机会在提供增强反馈时帮助教练。
