目的：本研究检验了用于测量高水平运动员下肢力量和爆发力的常见评估的重测信度。方法：本研究共招募了 100 名参与者，包括男性 (n = 83) 和女性 (n = 17) 运动员（21 [4] y、182 [9] cm 和 78 [12] kg） ，使用多中心方法。参与者接受了4次体能测试。前 2 次（第 1 次和第 2 次）相隔 1 周，然后是 2 到 6 个月，而最后 2 次（第 3 和 4 次）又相隔 1 周。测试方案包括深蹲跳跃、反向运动跳跃、跳跃和伸展、30 米短跑、1 次重复最大深蹲、短跑自行车和腿部推举测试。结果：所有评估的典型误差 (%) 范围为 1.3% 至 8.5%。所有评估的均值变化范围为 -1.5% 至 2.5%，而组间相关系数范围为 0.85 至 0.97。最小的有价值变化（基线 SD 的 0.2）范围为 1.2% 至 5.0%。典型误差 (%) 与最小有价值变化 (%) 之间的比率在 0.5 到 1.2 之间。在观察各个测试中心的可靠性时，观察到可靠性的显着差异（典型误差 [%] 比率：0.44–1.44）。结论：研究人员和教练可以自信地使用包含的大多数评估来衡量运动员的力量和爆发力。我们的结果强调了在每个测试中心控制测试可靠性以及不依赖其他数据的重要性，尽管应用了相同的协议。

Strength and Power Testing of Athletes: A Multicenter Study of Test–Retest Reliability
Purpose: This study examined the test–retest reliability of common assessments for measuring strength and power of the lower body in high-performing athletes. Methods: A total of 100 participants, including both male (n = 83) and female (n = 17) athletes (21 [4] y, 182 [9] cm, and 78 [12] kg), were recruited for this study, using a multicenter approach. The participants underwent physical testing 4 times. The first 2 sessions (1 and 2) were separated by ∼1 week, followed by a period of 2 to 6 months, whereas the last 2 sessions (3 and 4) were again separated by ∼1 week. The test protocol consisted of squat jumps, countermovement jumps, jump and reach, 30-m sprint, 1-repetition-maximum squat, sprint cycling, and a leg-press test. Results: The typical error (%) ranged from 1.3% to 8.5% for all assessments. The change in means ranged from −1.5% to 2.5% for all assessments, whereas the interclass correlation coefficient ranged from .85 to .97. The smallest worthwhile change (0.2 of baseline SD) ranged from 1.2% to 5.0%. The ratio between the typical error (%) and the smallest worthwhile change (%) ranged from 0.5 to 1.2. When observing the reliability across testing centers, considerable differences in reliability were observed (typical error [%] ratio: 0.44–1.44). Conclusions: Most of the included assessments can be used with confidence by researchers and coaches to measure strength and power in athletes. Our results highlight the importance of controlling testing reliability at each testing center and not relying on data from others, despite having applied the same protocol.
