Abstract The aim of this study was to compare the reliability, internal responsiveness and interchangeability of the Yo-Yo intermittent recovery test level 1 (YY1), level 2 (YY2) and submaximal YY1 (YY1-sub). Twenty-four young soccer players (age 17 ± 1 years; height 177 ± 7 cm; body mass 68 ± 6 kg) completed each test five times within pre- and in-season; distances covered and heart rates (HRs) were measured. Reliability was expressed as typical error of measurement (TEM) and intraclass correlation coefficient (ICC). Internal responsiveness was determined as effect size (ES) and signal-to-noise ratio (ES). Interchangeability was determined with correlation between training-induced changes. The TEM and ICC for distances in the YY1 and YY2 and for HR in YY1-sub were 7.3% and 0.78, 7.1% and 0.93 and 2.2% and 0.78, respectively. The ESs and ES were 0.9 and 1.9 for YY1, 0.4 and 1.2 for YY2 and -0.3 and -0.3 for YY1-sub. Correlations between YY1 vs. YY2 and YY1-sub were 0.56 to 0.84 and -0.36 to -0.81, respectively. Correlations between change scores in YY1 vs. YY2 were 0.29 and -0.21 vs. YY1-sub. Peak HR was higher in YY1 vs. YY2. The YY1 and YY2 showed similar reliability; however, they were not interchangeable. The YY1 was more responsive to training compared to YY2 and YY1-sub.
摘要 本研究旨在比较Yo-Yo间歇恢复测试1级（YY1）、2级（YY2）和次最大强度YY1（YY1-sub）的可靠性、内部反应性和互换性。24名年轻足球运动员（年龄17±1岁；身高177±7厘米；体重68±6千克）在赛季前和赛季中各完成了5次每项测试；测量了所跑距离和心率（HR）。可靠性用测量的典型误差（TEM）和组内相关系数（ICC）表示。内部反应性通过效应量（ES）和信噪比（ES）来确定。互换性通过训练引起的变化之间的相关性来确定。YY1和YY2中距离的TEM和ICC以及YY1-sub中心率的TEM和ICC分别为7.3%和0.78、7.1%和0.93以及2.2%和0.78。YY1的ES和ES分别为0.9和1.9，YY2为0.4和1.2，YY1-sub为-0.3和-0.3。YY1与YY2以及YY1-sub之间的相关性分别为0.56至0.84和-0.36至-0.81。YY1与YY2变化得分之间的相关性为0.29，与YY1-sub为-0.21。YY1中的最高心率高于YY2。YY1和YY2显示出相似的可靠性；然而，它们不可互换。与YY2和YY1-sub相比，YY1对训练的反应更灵敏。
