Lower reliability ratings for the youth group were likely due to lower video quality and the lack of players' tackling experience. Our study supports the effectiveness of tackling with the head up and making the initial contact with the inside shoulder. While intra- and interrater reliabilities were in the good range, these scores were lower in the youth group. During games, players used head-up, inside-shoulder tackles more successfully across all groups (97.5% YL, 99.5% MS, 98.8% HS). Coaches stated that they instructed players to "keep your head up," as currently recommended, 89% in YL, 100% in MS, and 81% in HS. In all groups, coaches responded that they preferred to teach the at-risk "head across the bow" tackling technique (83% YL, 81% MS, 75% HS). A subset of 100 consecutive tackles at each level of play was reviewed by 2 blinded reviewers to assess intra- and interrater reliabilities. Data were analyzed with the chi-square test. Survey data included how coaches instructed their players to tackle, the types of tackles, the number of tackles versus missed tackles, the head position, and the initial contact. Coaches provided video recordings of football games, and all tackle attempts were graded by a single reviewer who watched game videos 1000 consecutive tackles were observed for each group. Surveys were distributed via email to 500 coaches of YL, MS, and HS football teams in Texas. To assess (1) tackling techniques that coaches were teaching at 3 levels-youth level (YL 4th to 5th grades), middle school (MS 6th to 8th grades), and high school (HS 9th to 12th grades) (2) tackling techniques used during games and (3) the successful tackle rates of these techniques.
