Toffan, A, Alexander, MJL, and Peeler, J. Comparison of the technique of the football quarterback pass between high school and university athletes. J Strength Cond Res 32(9): 2474-2497, 2018-The purpose of the study was to compare the most effective joint movements, segment velocities, and body positions to perform the fastest and most accurate pass of high school and university football quarterbacks. Secondary purposes were to develop a quarterback throwing test to assess skill level, to determine which kinematic variables were different between high school and university athletes, and to determine which variables were significant predictors of quarterback throwing test performance. Ten high school and 10 university athletes were filmed for the study, performing 9 passes at a target and 2 passes for maximum distance. Thirty variables were measured using Dartfish Team Pro 4.5.2 video analysis system, and Microsoft Excel was used for statistical analyses. University athletes scored slightly higher than the high school athletes on the throwing test; however, this result was not statistically significant. Correlation analysis and forward stepwise multiple regression analysis were performed on both the high school players and the university players to determine which variables were significant predictors of throwing test score. Ball velocity was determined to have the strongest predictive effect on throwing test score (r = 0.900) for the high school athletes; however, position of the back foot at release was also determined to be important (r = 0.661) for the university group. Several significant differences in throwing technique between groups were noted during the pass; however, body position at release showed the greatest differences between the 2 groups. High school players could benefit from more complete weight transfer and decreased throw time to increase throwing test score. University athletes could benefit from increased throw time and greater range of motion in external shoulder rotation and trunk rotation to increase their throwing test score. Coaches and practitioners will be able to use the findings of this research to help improve these and related throwing variables in their high school and university quarterbacks.
托法恩、亚历山大、MJL 和皮勒研究了高中和大学足球四分卫传球技术的比较。《力量与调节研究杂志》32（9）：2474-2497，2018-本研究的目的是比较执行最快和最准确传球时最有效的关节运动、节段速度和身体姿势，以实现高中和大学四分卫传球技术的比较。次要目的是开发四分卫投掷测试以评估技能水平，确定高中和大学运动员之间哪些运动学变量不同，以及确定哪些变量是四分卫投掷测试表现的重要预测指标。研究拍摄了 10 名高中和 10 名大学运动员向目标传球 9 次，向最大距离传球 2 次。使用 Dartfish Team Pro 4.5.2 视频分析系统测量了 30 个变量，使用 Microsoft Excel 进行统计分析。大学运动员在投掷测试中的得分略高于高中运动员；然而，这一结果没有统计学意义。对高中运动员和大学运动员进行相关分析和逐步向前多元回归分析，以确定哪些变量是投掷测试得分的显著预测指标。球速被确定为对高中运动员投掷测试得分具有最强的预测效果（r=0.900）；然而，后脚在释放时的位置对大学组也很重要（r=0.661）。在传球过程中，注意到两组之间的投掷技术存在一些显著差异；然而，释放时的身体位置显示出两组之间最大的差异。高中运动员可以通过更完整的体重转移和减少投掷时间来提高投掷测试得分。大学运动员可以通过增加投掷时间和增加肩部外旋和躯干旋转的运动范围来提高他们的投掷测试得分。教练和从业者将能够利用这项研究的结果来帮助提高他们的高中和大学四分卫的这些和相关的投掷变量。
