This study aimed to examine the reliability and validity of a head-marking version of the taekwondo anaerobic intermittent kick test (TAIKT-head). Twenty-seven (21 males and 6 females) taekwondo athletes performed TAIKT-head on two occasions (test-retest). In addition, they performed the chest-marking version of the TAIKT (TAIKT-chest), 30-s continuous jump (CJ30s), countermovement jump (CMJ) and flexibility tests. To establish TAIKT-head's construct validity (discriminatory capability), two subgroups were identified based on their international and national taekwondo results: 15 elite (12 males and 3 females) and 12 sub-elite (9 males and 3 females) athletes. TAIKT-head showed high relative (ICCs ≥ 0.90) and absolute (SEMs < SWCs) reliability. The comparison between TAIKT-head and TAIKT-chest revealed that absolute and relative peak and mean powers were higher (p < 0.001) in TAIKT-head than in TAIKT-chest. In contrast, the fatigue index and rating of perceived exertion were lower in TAIKT-head than in TAIKT-chest (p < 0.001 and p < 0.01, respectively), with no significant difference between the two tests regarding physiological variables. Significant correlations between TAIKT-head and TAIKT-chest (r ranged from 0.74 to 0.53), CJ30s (r ranged from 0.84 to 0.43), and CMJ (r ranged from 0.88 to 0.79) were mostly "very large". There was no association between TAIKT-head and flexibility tests. Elite athletes showed greater TAIKT-head performances than sub-elite counterparts. Receiving operating characteristic analysis indicated that the TAIKT-head effectively discriminated between elite and sub-elite athletes. In conclusion, the TAIKT-head is a reliable and valid test to evaluate the specific intermittent anaerobic power of taekwondo athletes through the most used kicking technique at the head level.
本研究旨在检验跆拳道无氧间歇踢腿测试头部标记版本（TAIKT-head）的信度和效度。27名（21名男性和6名女性）跆拳道运动员进行了两次TAIKT-head测试（重测）。此外，他们还进行了TAIKT胸部标记版本（TAIKT-chest）、30秒连续跳跃（CJ30s）、反向移动跳跃（CMJ）和柔韧性测试。为了确定TAIKT-head的结构效度（区分能力），根据国际和国家跆拳道成绩将运动员分为两个亚组：15名精英运动员（12名男性和3名女性）和12名次精英运动员（9名男性和3名女性）。TAIKT-head显示出较高的相对（组内相关系数≥0.90）和绝对（测量标准误差<标准差变化系数）信度。TAIKT-head与TAIKT-chest的比较显示，TAIKT-head的绝对和相对峰值功率及平均功率均高于TAIKT-chest（p<0.001）。相比之下，TAIKT-head的疲劳指数和主观用力程度评分低于TAIKT-chest（分别为p<0.001和p<0.01），两项测试在生理变量方面无显著差异。TAIKT-head与TAIKT-chest（r值范围为0.74至0.53）、CJ30s（r值范围为0.84至0.43）和CMJ（r值范围为0.88至0.79）之间的显著相关性大多为“非常强”。TAIKT-head与柔韧性测试之间无关联。精英运动员在TAIKT-head测试中的表现优于次精英运动员。受试者工作特征分析表明，TAIKT-head能够有效区分精英和次精英运动员。总之，TAIKT-head是一种可靠且有效的测试，可通过在头部水平最常用的踢腿技术来评估跆拳道运动员的特定间歇性无氧功率。
