To measure the absolute and relative reliability and the smallest real difference (SRD) in three commonly used hop tests, two leg-power tests and the single-leg squat jump.
Methodological study.
Clinical setting.
Fourteen healthy athletes (seven women and seven men) were evaluated in a standardized test-retest design.
The Intra-class correlation coefficient (ICC2.1), Standard Error of Measurement (SEM) and SRD were calculated for the vertical jump, one-leg hop for distance, side-hop, single-leg squat jump and knee-flexion and knee-extension power tests.
All tests showed good to excellent ICC (0.84-0.98). The SEM (%) ranged between 3.4 and 11.1 for the four hop tests and between 8.1 and 12.4 for the leg-power tests. The SRD (%) for the hop tests ranged between 9.3 and 30.7 and for the three power tests between 22.4 and 34.3.
The absolute reliability of this test protocol showed good to excellent ICC values and measurement errors of approximately 10%. This instrument can be recommended for determining function in terms of power in healthy athletes or late in the rehabilitation process. The tests' methodological errors must be considered and caution should be taken regarding the standardization procedure during testing.
测量三种常用跳跃测试、两种腿部力量测试以及单腿深蹲跳的绝对可靠性、相对可靠性和最小真实差异（SRD）。
方法学研究。
临床环境。
14名健康运动员（7名女性和7名男性）在标准化的重测设计中接受评估。
计算垂直跳、单腿跳远、侧向跳、单腿深蹲跳以及屈膝和伸膝力量测试的组内相关系数（ICC2.1）、测量标准误（SEM）和SRD。
所有测试的ICC均显示良好至优秀（0.84 - 0.98）。四项跳跃测试的SEM（%）在3.4至11.1之间，腿部力量测试的SEM（%）在8.1至12.4之间。跳跃测试的SRD（%）在9.3至30.7之间，三项力量测试的SRD（%）在22.4至34.3之间。
该测试方案的绝对可靠性显示出良好至优秀的ICC值，测量误差约为10%。该仪器可推荐用于确定健康运动员的力量功能或康复后期的功能。必须考虑测试的方法学误差，并且在测试过程中应注意标准化程序。
