Until recently, measurement and evaluation in sport science, especially agility testing, has not always included key elements of proper test construction. Often tests are published without reporting reliability and validity analysis for a specific population. The purpose of the present study was to examine the test re-test reliability of four versions of the 3-Cone Test (3CT), and provide guidance on proper test construction for testing agility in athletic populations. Forty male students enrolled in classes in the Department of Physical Education at a mid-Atlantic university participated. On each of test day participants performed 10 trials. In random order, they performed three trials to the right (3CTR, standard test), three to the left (3CTL), and two modified trials (3CTAR and 3CTAL), which included a reactive component in which a visual cue was given to indicate direction. Intra-class correlation coefficients (ICC) indicated a moderate to high reliability for the four tests, 3CTR 0.79 (0.64-0.88, 95%CI), 3CTL 0.73 (0.55-0.85), 3CTAR 0.85(0.74-0.92), and 3CTAL 0.79 (0.64-0.88). Small standard error of the measurement (SEM) was found; range 0.09 to 0.10. Pearson correlations between tests were high (0.82-0.92) on day one as well as day two (0.72-0.85). These results indicate each version of the 3-Cone Test is reliable; however, further tests are needed with specific athletic populations. Only the 3CTAR and 3CTAL are tests of agility due to the inclusion of a reactive component. Future studies examining agility testing and training should incorporate technological elements, including automated timing systems and motion capture analysis. Such instrumentation will allow for optimal design of tests that simulate sport-specific game conditions.
直到最近，体育科学中的测量与评估，尤其是敏捷性测试，并不总是包含恰当测试构建的关键要素。通常，测试在发表时并未针对特定人群报告信效度分析。本研究的目的是检验3种不同版本的3-锥体测试（3CT）的重测信度，并为在运动员群体中测试敏捷性的恰当测试构建提供指导。来自大西洋中部一所大学体育系的40名男学生参与了研究。在每个测试日，参与者进行10次测试。他们以随机顺序进行3次向右的测试（3CTR，标准测试）、3次向左的测试（3CTL）以及2次改良测试（3CTAR和3CTAL），改良测试包含一个反应成分，即通过视觉提示来指明方向。组内相关系数（ICC）表明这4种测试具有中等到高度的信度，3CTR为0.79（0.64 - 0.88，95%置信区间），3CTL为0.73（0.55 - 0.85），3CTAR为0.85（0.74 - 0.92），3CTAL为0.79（0.64 - 0.88）。测量的标准误较小；范围为0.09至0.10。测试之间的皮尔逊相关性在第一天较高（0.82 - 0.92），在第二天也较高（0.72 - 0.85）。这些结果表明3-锥体测试的每个版本都是可靠的；然而，还需要对特定运动员群体进行进一步测试。由于包含反应成分，只有3CTAR和3CTAL是敏捷性测试。未来研究敏捷性测试与训练时应纳入技术要素，包括自动计时系统和动作捕捉分析。这样的仪器将有助于优化模拟特定运动比赛条件的测试设计。
