Submaximal field tests are especially recommended when repeated testing is warranted. This study aimed at assessing the validity of the submaximal versions of the Yo-Yo intermittent tests in male recreational football players in untrained and trained status. The participants' (n = 66; age 39.3 ± 5.8 years, VO 41.2 ± 6.2 mL·kg ·min , body mass 81.9 ± 10.8 kg, height 173.2 ± 6.4 cm) heart rate after 2 minutes (HR ) during the level 1 (YYIE1 ) and 2 (YYIE2 ) versions of the Yo-Yo intermittent endurance test and the level 1 version of the Yo-Yo intermittent recovery test (YYIR1 ) was plotted against individual VO values. Thirty-two participants performed all the tests after a 12-week recreational football intervention for test responsiveness. Associations between VO and YYIE1 were large to small (P = .0001). Large to trivial associations were found between YYIE2 , YYIR1 , and VO (P < .01). Maximal Yo-Yo performances were large, significant, and inversely related to HR (-0.68 to -0.49, P < .0001). Pre- to post-intervention ICC values were good for YYIE1 and YYIE2 , and excellent for YYIR1 . Post-intervention associations between HR and Yo-Yo maximal performances were large to very large (-0.55 to -0.72; P < .002, n = 32). Training-induced changes in VO moderately correlated with YYIR1 (-0.48; P = .007; n = 32). HR lower than 89%, 98%, and 91% HR for YYIE1 , YYIE2 , and YYIR1 , respectively, may be considered as signs of good to excellent VO levels. Since in the YYIE1 , the participants attained 84% HR and test specificity increased for HR values <89%, this test may be the preferred choice when repeated assessment of aerobic fitness, using submaximal intermittent Yo-Yo tests, is considered in recreational football.
当需要重复测试时，特别推荐进行次最大强度测试。本研究旨在评估在未经训练和训练的男性业余足球运动员中，Yo-Yo 间歇性测试的次最大版本的有效性。参与者（n=66；年龄 39.3±5.8 岁，VO 41.2±6.2mL·kg·min-1，体重 81.9±10.8kg，身高 173.2±6.4cm）在 Yo-Yo 间歇性耐力测试的第 1 级（YYIE1）和第 2 级（YYIE2）以及 Yo-Yo 间歇性恢复测试的第 1 级（YYIR1）后 2 分钟的心率（HR）与个体 VO 值相对应。32 名参与者在经过 12 周的业余足球干预后进行了所有测试，以测试反应性。VO 与 YYIE1 之间的关联为大到小（P=.0001）。YYIE2、YYIR1 和 VO 之间存在大到微不足道的关联（P<.01）。最大 Yo-Yo 表现与 HR 呈负相关（-0.68 至-0.49，P<.0001），且为大、显著、反向相关。YYIE1 和 YYIE2 的 ICC 值良好，YYIR1 的 ICC 值极好。HR 与 Yo-Yo 最大表现之间的干预后关联为大到非常大（-0.55 至-0.72；P<.002，n=32）。VO 的训练诱导变化与 YYIR1 中度相关（-0.48；P=.007；n=32）。YYIE1、YYIE2 和 YYIR1 的 HR 分别低于 89%、98%和 91%HR 可能被视为良好到优秀 VO 水平的标志。由于在 YYIE1 中，参与者达到了 84%的 HR，并且 HR 值<89%的测试特异性增加，因此当考虑在业余足球中使用次最大强度间歇 Yo-Yo 测试对有氧适能进行重复评估时，该测试可能是首选。
