The purpose of the study was to determine if six weeks of plyometric training can improve an athlete's agility. Subjects were divided into two groups, a plyometric training and a control group. The plyometric training group performed in a six week plyometric training program and the control group did not perform any plyometric training techniques. All subjects participated in two agility tests: T-test and Illinois Agility Test, and a force plate test for ground reaction times both pre and post testing. Univariate ANCOVAs were conducted to analyze the change scores (post - pre) in the independent variables by group (training or control) with pre scores as covariates. The Univariate ANCOVA revealed a significant group effect F2,26 = 25.42, p=0.0000 for the T-test agility measure. For the Illinois Agility test, a significant group effect F2,26 = 27.24, p = 0.000 was also found. The plyometric training group had quicker posttest times compared to the control group for the agility tests. A significant group effect F2,26 = 7.81, p = 0.002 was found for the Force Plate test. The plyometric training group reduced time on the ground on the posttest compared to the control group. The results of this study show that plyometric training can be an effective training technique to improve an athlete's agility. Key PointsPlyometric training can enhance agility of athletes.6 weeks of plyometric training is sufficient to see agility results.Ground reaction times are decreased with plyometric training.
本研究的目的是确定六周的增强式训练是否能提高运动员的敏捷性。受试者被分为两组，一组进行增强式训练，另一组为对照组。增强式训练组进行了六周的增强式训练计划，对照组则没有进行任何增强式训练技术。所有受试者都参加了两项敏捷性测试：T 测试和伊利诺伊敏捷性测试，以及力板测试以测量地面反应时间，在测试前后都进行了测试。使用单变量协方差分析（ANCOVA），根据组（训练或对照）分析独立变量（后测-前测）的变化分数，将前测作为协变量。单变量协方差分析显示 T 测试敏捷性测量的组间效应显著 F2,26 = 25.42，p=0.0000。对于伊利诺伊敏捷性测试，也发现了显著的组间效应 F2,26 = 27.24，p = 0.000。与对照组相比，增强式训练组在敏捷性测试中的后测时间更快。力板测试也发现了显著的组间效应 F2,26 = 7.81，p = 0.002。与对照组相比，增强式训练组在后测时在地面上的时间减少。本研究的结果表明，增强式训练可以是一种有效的训练技术，以提高运动员的敏捷性。要点增强式训练可以提高运动员的敏捷性。六周的增强式训练足以看到敏捷性的结果。增强式训练可减少地面反应时间。
