The main objective of present study was to evaluate inter-rater reliability and concurrent validity of Side Hop Test stopwatch vs. force plates timing, and to determine the number of sessions and trials required to minimize the effects of learning on Side Hop Test total time and limb symmetry index. Fifteen healthy male physical education students (mean ± SD: age, 23 ± 3 years; height, 181 ± 9 cm; and weight 72 ± 6 kg) participated. Side Hop Test total time (stopwatch and force plates) of left and right leg, and limb symmetry index (force plates) were obtained over seven sessions conducted 5-7 days apart. Time recordings of two raters were similar ( = -0.56, > 0.05) with high reliability (all ICC >0.99 and CV% <0.1) and no systematic bias when compared to force plate data ( > 0.05; for rater 1 and 2, respectively). Total time improved across the Sessions ( = 25.87, < 0.01, = 0.18) and Trials ( = 68.15, < 0.01, = 0.10), with no significant interaction between factors. No between-leg differences were detected ( = 0.52, > 0.05, = 0.001). Limb symmetry index ranged from 0.999 to 1.055 across all sessions and trials (all > 0.05 and < 0.00). Due to low coefficient of correlation, high interclass correlation coefficient, and the lack in heteroscedasticity, stopwatch measurements are valid to measure total time in the Side Hop Test. Moreover, stopwatch measurements could be reliably used to measure total time in the Side Hop Test, while the test could be administrated with only one experienced rater. Unlike total times, findings on limb symmetry index suggest it could be reliably assessed after seven familiarization sessions.
本研究的主要目的是评估侧跳测试中秒表计时与测力板计时之间的评分者间信度和同时效度，并确定将学习对侧跳测试总时间和肢体对称指数的影响降至最低所需的训练次数和测试次数。15名健康的男性体育专业学生（平均±标准差：年龄，23±3岁；身高，181±9厘米；体重72±6千克）参与了研究。在相隔5 - 7天进行的7次训练中，获取了左腿和右腿的侧跳测试总时间（秒表和测力板）以及肢体对称指数（测力板）。与测力板数据相比，两名评分者的时间记录相似（r = -0.56，p > 0. .05），具有高信度（所有组内相关系数ICC > 0.99且变异系数CV% < 0.1）且无系统偏差（p > 0.05；分别针对评分者1和评分者2）。总时间在各训练阶段（F = 25.87，p < 0.01，η² = 0.18）和各测试次数（F = 68.15，p < 0.01，η² = 0.10）上均有所改善，各因素之间无显著交互作用。未检测到两腿之间的差异（F = 0.52，p > 0.05，η² = 0.001）。在所有训练阶段和测试次数中，肢体对称指数范围为0.999至1.055（所有p > 0.05且η² < 0.00）。由于低相关系数、高组内相关系数以及不存在异方差性，秒表测量对于测量侧跳测试的总时间是有效的。此外，秒表测量可可靠地用于测量侧跳测试的总时间，且该测试仅由一名经验丰富的评分者进行即可。与总时间不同，关于肢体对称指数的结果表明，在7次熟悉训练后可以可靠地进行评估。
