The aims of this study were (a) to assess and correlate interval shuttle run test (ISRT) performance, maximum oxygen uptake (V[Combining Dot Above]O(2)max), running economy (RE), running velocity at the first rise in blood lactate concentrations above baseline (vLT) and running velocity at 4 mmol·L(-1) blood lactate concentration (v4) in professional soccer players and (b) to investigate whether a correlation exists between the respective results of time to exhaustion (T(lim)) from continuous and intermittent endurance tests, respectively. Eleven male professional field soccer players (mean ± SD: age 23.8 ± 3.0 years, V[Combining Dot Above]O(2)max 58.2 ± 4.9 ml·kg(-1)·min(-1)) completed a continuous Incremental Test with lactate measurements to determine vLT and v4, a continuous Ramp Test with gas exchange analysis to determine V[Combining Dot Above]O(2)max and RE, and an intermittent ISRT to determine intermittent endurance capacity during the first week of preseason preparation. There were significant correlations between ISRT performance and V[Combining Dot Above]O(2)max (r = 0.70, p < 0.05), and between T(lim) in both continuous endurance tests (r = 0.89, p < 0.01). Between all other variables no significant correlations were found overall (best r = 0.60, p > 0.05). The assessment of all values of V[Combining Dot Above]O(2)max, RE, vLT, and v4 should be included when investigating aerobic endurance performance among groups or over time in professional soccer players. Although V[Combining Dot Above]O(2)max, RE, vLT, and v4 have been regarded as important factors of aerobic performance in endurance related sports, the present data revealed that V[Combining Dot Above]O(2)max was the only factor, which correlated with intermittent endurance capacity in professional soccer players. Hence, V[Combining Dot Above]O(2)max should be increased through soccer-specific training interventions including universal agility components. The T(lim) in continuous and intermittent endurance tests differs and is therefore an independent endurance performance factor in professional soccer players.
(a) 评估和关联间歇冲刺跑测试 (ISRT) 表现、最大摄氧量 (V[Combining Dot Above]O(2)max)、运动经济性 (RE)、血液乳酸浓度基线上升时的第一上升速度 (vLT) 和血液乳酸浓度为 4mmol·L(-1) 时的速度 (v4) 在职业足球运动员中的相关性；(b) 分别研究连续和间歇性耐力测试的时间限制 (T(lim)) 的结果之间是否存在相关性。11 名男性职业足球运动员（平均 ± 标准差：年龄 23.8 ± 3.0 岁，V[Combining Dot Above]O(2)max 58.2 ± 4.9 ml·kg(-1)·min(-1)) 在季前准备的第一周完成了一项带有乳酸测量的连续递增测试，以确定 vLT 和 v4；一项带有气体交换分析的连续斜坡测试，以确定 V[Combining Dot Above]O(2)max 和 RE；以及一项间歇 ISRT，以确定间歇耐力能力。ISRT 表现与 V[Combining Dot Above]O(2)max 之间存在显著相关性（r = 0.70，p < 0.05），而在两个连续耐力测试中，T(lim) 之间也存在显著相关性（r = 0.89，p < 0.01）。总体而言，其他所有变量之间没有发现显著相关性（最佳 r = 0.60，p > 0.05）。在研究职业足球运动员中的有氧耐力表现时，应包括所有 V[Combining Dot Above]O(2)max、RE、vLT 和 v4 值的评估。尽管 V[Combining Dot Above]O(2)max、RE、vLT 和 v4 一直被认为是与耐力相关运动中有氧表现的重要因素，但目前的数据表明，V[Combining Dot Above]O(2)max 是唯一与职业足球运动员间歇耐力能力相关的因素。因此，应通过包括通用敏捷性成分的足球专项训练干预来提高 V[Combining Dot Above]O(2)max。连续和间歇耐力测试中的 T(lim) 不同，因此是职业足球运动员独立的耐力表现因素。
