BACKGROUND
the purpose of this study was to verify the validity of respiratory compensation threshold (RCT) measured during a new single judo specific incremental test (JSIT) for aerobic demand evaluation.
METHODS
to test the validity of the new test, the JSIT was compared with Maximal Lactate Steady State (MLSS), which is the gold standard procedure for aerobic demand measuring. Eight well-trained male competitive judo players (24.3 ± 7.9 years; height of 169.3 ± 6.7cm; fat mass of 12.7 ± 3.9%) performed a maximal incremental specific test for judo to assess the RCT and performed on 30-minute MLSS test, where both tests were performed mimicking the UchiKomi drills.
RESULTS
the intensity at RCT measured on JSIT was not significantly different compared to MLSS (p=0.40). In addition, it was observed high and significant correlation between MLSS and RCT (r=0.90, p=0.002), as well as a high agreement.
CONCLUSIONS
RCT measured during JSIT is a valid procedure to measure the aerobic demand, respecting the ecological validity of Judo.
背景
本研究的目的是验证在一种新的单一柔道专项递增测试（JSIT）过程中测得的呼吸补偿阈值（RCT）用于评估有氧需求的有效性。
方法
为测试新测试的有效性，将JSIT与最大乳酸稳态（MLSS）进行比较，MLSS是测量有氧需求的金标准程序。八名训练有素的男性竞技柔道运动员（24.3±7.9岁；身高169.3±6.7厘米；体脂12.7±3.9%）进行了一项柔道专项最大递增测试以评估RCT，并进行了30分钟的MLSS测试，两项测试均模仿内股练习进行。
结果
JSIT测得的RCT强度与MLSS相比无显著差异（p = 0.40）。此外，观察到MLSS与RCT之间存在高度显著相关性（r = 0.90，p = 0.002），以及高度一致性。
结论
JSIT过程中测得的RCT是一种有效的测量有氧需求的方法，符合柔道的生态有效性。
