Athletes regularly have to pass a series of tests, among which one of the most frequently used functional performance measures are single-leg hop tests. As the collected individual results of tests constitute a large amount of data, strategies to decrease the amount of data without reducing the number of performed tests are being searched for. Therefore, the study aimed to present an effective method to reduce the hop-test battery data to a single score, namely, the Compound Hop Index (CHI) in the example of a soccer team. A male, first-league soccer team performed a battery of commonly used single-leg hop tests, including single hop and triple hop for distance tests and the six-meter timed hop test. Gathered data, including Limb Symmetry Indexes of the three tests, normalized to body height for the single- and triple-hop-tests distance separately for right and left legs, and the time of the six-meter timed hop test separately for right and left legs were standardized to z-scores. Consecutively, the z-scores were averaged and formed CHI. The developed CHI represents a novel score derived from the average of z-scores that significantly reduces, clarifies, and organizes the hop performance-measures data.
运动员经常要通过一系列测试，其中最常用的功能表现测量方法之一是单腿跳测试。由于收集到的个人测试结果构成了大量数据，人们正在寻找在不减少测试次数的情况下减少数据量的策略。因此，本研究旨在提出一种有效的方法，以将跳测试组的数据简化为一个单一分数，即以一支足球队为例的复合跳指数（CHI）。一支男子甲级足球队进行了一系列常用的单腿跳测试，包括单跳和三跳的距离测试以及六米定时跳测试。收集的数据，包括三项测试的肢体对称指数，单跳和三跳测试的距离分别针对右腿和左腿按身高进行归一化，六米定时跳测试的时间分别针对右腿和左腿标准化为z分数。随后，将z分数进行平均并形成CHI。所开发的CHI代表了一种从z分数平均值得出的新分数，它显著减少、澄清并整理了跳性能测量数据。
