The main aim of this study was to determine the test-retest reliability of an experimental functional test battery: Y-balance test (YBT), single-leg countermovement jump (SLCMJ), single-leg hop for distance (SLH), side-hop (SH), speedy-jump (SJ), agility-T (AT), and lower extremity functional test (LEFT). Secondary aims were (1) to determine the mean range for the limb symmetry index (LSI) and (2) to detect significant differences in performance between test-retest sessions. Twenty-two healthy adults (14 males, 8 females; age 23.3 ± 3.9) were tested by the same rater during two different sessions (T1-T2), with a seven-day interval, under the same conditions. Reliability analysis showed good-to-excellent reliability (0.89 < ICC < 0.97; 0.80 < α < 0.98) for the test battery. LSI ranged from 95.9 ± 6.7% (SH-T1) to 104.4 ± 12.5% (SLCMJ-T2). Repeated measures ANOVA detected significant performance differences between sessions in the LEFT ( = 0.009) and for non-dominant sides in the SLH ( = 0.015), SH ( = 0.007), and SJ ( = 0.011). The high reliability of the test battery suggests a potential use in clinical sports practice. The LSI range of ≥95% was proposed as a benchmark for healthy adults. Learning effect seems to have played a crucial role in the T2 improvements of the non-dominant side for hop performances (SLH, SH, SJ) and speed performance (LEFT).
Y平衡测试（YBT）、单腿反向跳（SLCMJ）、单腿跳远（SLH）、侧向跳（SH）、快速跳（SJ）、敏捷T测试（AT）以及下肢功能测试（LEFT）。次要目的包括：（1）确定肢体对称指数（LSI）的平均范围；（2）检测重测环节之间的表现是否存在显著差异。22名健康成年人（14名男性，8名女性；年龄23.3±3.9岁）在相同条件下，由同一名评估者在两个不同时段（T1 - T2）进行测试，间隔七天。可靠性分析表明该测试组合具有良好至优秀的信度（0.89 < ICC < 0.97；0.80 < α < 0.98）。LSI范围从95.9±6.7%（SH - T1）至104.4±12.5%（SLCMJ - T2）。重复测量方差分析检测到LEFT测试（P = 0.009）以及SLH、SH和SJ测试中非优势侧在不同时段之间存在显著的表现差异（P = 0.015、P = 0.007、P = 0.011）。该测试组合的高信度表明其在临床运动实践中具有潜在用途。建议将≥95%的LSI范围作为健康成年人的基准。学习效应似乎在非优势侧跳跃表现（SLH、SH、SJ）和速度表现（LEFT）的T2改善中起到了关键作用。
