Previous studies have found that injury rates are slightly higher in children who play flag football versus tackle football. It is unclear if this difference is due to the way each type is played or taught or whether there are intrinsic differences in attitudes or neuropsychological characteristics in children and their parents.
To determine whether children who play flag football score differently from those who play tackle football on validated neuropsychological tests.
Cross-sectional study; Level of evidence, 3.
Each participating athlete (aged 8-12 years) was recruited in 2018 and 2019 by email through local youth football leagues and the local university. Each athlete was administered a 1-time multidimensional assessment battery. The battery included the Wechsler Abbreviated Scale of Intelligence-2nd Edition, the children's version of the Trail Making Test, the Integrated Digit Span and Spatial Span subtests of the Wechsler Intelligence Scale for Children-4th Edition (WISC-IV), and the Beck Self-Concept Inventory for Youth. The parent/guardian of each athlete completed the Achenbach Child Behavior Checklist-Parent Report Form, the Behavior Rating Inventory of Executive Function (BRIEF)-Parent Form, and a custom survey. These tests were used to determine IQ estimates and standardized scores, measuring verbal comprehension, matrix reasoning, mental set-shifting, attention, cognitive processing speed, working memory, spatial processing, perception of self-concept, behavioral regulation index, metacognition index, and global executive composite. Scores were compared between flag football and tackle football groups by 2-sample test, with the Wilcoxon rank-sum test used for nonparametric data.
A total of 64 athletes (41 tackle football, 23 flag football) were enrolled from youth football leagues (grades 4-6). Flag players scored significantly higher on the WISC-IV Spatial Span-Backward subtest (scaled mean, 12.0 vs 10.6; = .046), while tackle players had significantly higher BRIEF-Inhibit subscores (mean -score, 45 vs 42; = .026). There were no significant differences in any of the other tests, including socioeconomic status and perceived concussion risks.
Concerns that injury epidemiologic studies comparing flag with tackle football could be confounded by intrinsic differences in the children who choose to play each type seem to be unfounded.
先前的研究发现,与进行擒抱式橄榄球运动的儿童相比,进行腰旗式橄榄球运动的儿童受伤率略高。目前尚不清楚这种差异是由于每种运动的玩法或教学方式不同,还是因为儿童及其父母在态度或神经心理特征方面存在内在差异。
确定在经过验证的神经心理测试中,进行腰旗式橄榄球运动的儿童与进行擒抱式橄榄球运动的儿童得分是否存在差异。
横断面研究;证据等级为3级。
2018年和2019年,通过电子邮件,从当地青少年橄榄球联盟和当地大学招募了每位参与研究的运动员(年龄在8至12岁之间)。对每位运动员进行了一次多维度评估测试。该测试包括韦氏儿童智力量表简式第二版、儿童版连线测验、韦氏儿童智力量表第四版(WISC-IV)的数字广度综合测验和空间广度分测验,以及青少年贝克自我概念量表。每位运动员的家长/监护人完成了阿肯巴克儿童行为量表家长报告表、执行功能行为评定量表(BRIEF)家长版,以及一份定制调查问卷。这些测试用于确定智商估计值和标准化分数,测量言语理解、矩阵推理、思维转换、注意力、认知处理速度、工作记忆空间处理、自我概念感知、行为调节指数、元认知指数和整体执行能力综合得分。通过双样本t检验比较腰旗式橄榄球组和擒抱式橄榄球组的得分,对于非参数数据使用威尔科克森秩和检验。
从青少年橄榄球联盟(4至6年级)共招募了64名运动员(41名进行擒抱式橄榄球运动,23名进行腰旗式橄榄球运动)。腰旗式橄榄球运动员在WISC-IV空间广度倒序分测验中的得分显著更高(量表平均分,12.0对10.6;P = 0.046),而擒抱式橄榄球运动员的BRIEF抑制子得分显著更高(平均得分,45对42;P = 0.026)。在包括社会经济地位和感知脑震荡风险在内的任何其他测试中均未发现显著差异。
关于比较腰旗式橄榄球和擒抱式橄榄球的损伤流行病学研究可能会因选择参与每种运动的儿童的内在差异而产生混淆的担忧似乎没有根据。
