The purpose of this study was to examine the test-retest reliability and minimal detectable change (MDC95) of the hexagon test. The hexagon test is a routinely used measure of agility in the sports and rehabilitation professions, yet its reliability has not been investigated in prior research. A total of 26 college-aged men (n = 17) and women (n = 9) of various activity levels were recruited to participate in 3 testing sessions: baseline, 1 hour after baseline, and 48 hours after baseline. The results of this study indicated excellent test-retest reliability for both same-day intraclass correlation coefficient (ICC) model 3,1 = 0.938 and between-day ICC (3,1) = 0.924 analyses. The MDC95 for the hexagon test was 1.015 seconds. A significant difference in the mean times was identified during the same-day test-retest sessions (p < 0.001) but not the between-day test-retest sessions (p = 0.18). The significant differences identified between the baseline and the same-day retest session suggests a learning effect. The hexagon test shows excellent reliability for measuring agility, which supports its use as a tool to assess athletic performance and lower-extremity agility. Evidence of reliability, in addition to its ease of administration, makes the hexagon test a practical and effective method to measure agility. When using this test as a measure of agility, a change of greater than 1.015 seconds is necessary to be 95% certain that the change in time reflects improvement and exceeds measurement error. A practice trial is recommended prior to recording scores to attenuate the possibility of a learning effect.
本研究旨在检验六边形测试的重测信度和最小可检测变化（MDC95）。六边形测试是运动和康复领域常用的敏捷性测量方法，但之前的研究并未对其可靠性进行调查。共有 26 名不同活动水平的大学生（男性 n = 17，女性 n = 9）参加了 3 次测试：基线、基线后 1 小时和基线后 48 小时。本研究结果表明，当天内组内相关系数（ICC）模型 3,1 = 0.938 和两天间 ICC（3,1）= 0.924 分析的重测信度均非常好。六边形测试的 MDC95 为 1.015 秒。在同一天的重测测试中，发现平均用时存在显著差异（p < 0.001），但在两天间的重测测试中没有差异（p = 0.18）。在同一天的重测测试中，基线和重测之间的显著差异表明存在学习效应。六边形测试在测量敏捷性方面具有极好的可靠性，这支持了它作为评估运动表现和下肢敏捷性的工具的使用。除了易于管理外，可靠性的证据使其成为测量敏捷性的实用和有效的方法。当使用此测试作为敏捷性的衡量标准时，需要大于 1.015 秒的变化才能有 95%的把握确定时间的变化反映了改进并且超过了测量误差。建议在记录分数之前进行练习试验，以减少学习效应的可能性。
