The purpose of this study was to assess the effectiveness of regulations and behavioral interventions on head impacts and concussions in youth, high-school, and collegiate football, using a systematic search strategy to identify relevant literature. Six databases were searched using key search terms related to three categories: football, head-injuries, and interventions. Studies that met inclusion criteria were included in the study and underwent data extraction. Twenty articles met inclusion criteria and were included in the final systematized review. Of the 20 included studies, 8 studies evaluated interventions in high-school football, 5 studies evaluated interventions in collegiate football, 6 studies evaluated interventions in youth football, and 1 study evaluated interventions in both, high-school and collegiate football. The four categories of interventions and regulations included rule changes, training, education/instruction/coaching tactical changes, and tackle football alternatives. Studies evaluating the effectiveness of interventions and regulations on reducing head impact exposures or head injuries have shown mixed results. Some regulations may be more effective than others, but methodological design and risk of bias pose limitations to generalize effects.

本研究的目的是评估法规和行为干预对青少年、高中和大学生足球的头部撞击和脑震荡的有效性，使用系统的搜索策略来识别相关文献。使用与以下三个类别相关的关键搜索词搜索了六个数据库：足球、头部受伤和干预。符合纳入标准的研究被纳入研究并进行数据提取。二十篇文章符合纳入标准，并被纳入最终的系统化审查。在纳入的 20 项研究中，8 项研究评估了高中橄榄球的干预措施，5 项研究评估了大学橄榄球的干预措施，6 项研究评估了青少年足球的干预措施，1 项研究评估了高中和大学橄榄球的干预措施。这四类干预措施和规定包括规则变更、培训、教育/指导/教练战术变更和解决足球备选方案。评估干预措施和法规对减少头部撞击暴露或头部受伤的有效性的研究显示出不同的结果。有些法规可能比其他法规更有效，但方法设计和偏倚风险限制了推广效果。
