Practitioners place importance on high-speed running (HSR) to monitor training practice and match-play demands, whilst attempting to maximise fitness and minimize the risk of injury occurrence. Practitioners apply various methods to quantify HSR, such as absolute thresholds, percentage of maximum sprint speed and maximal aerobic speed (MAS). A recent survey demonstrates the 5-minute run and 1200m shuttle test (ST) to be implemented among rugby league practitioners to quantify HSR by incorporating MAS. However, it is unclear as to how valid these methods are to accurately quantify MAS. Therefore, the aim of this study was to assess the validity of the 5-minute run and 1200m ST when compared to a gold standard measure for MAS. Twenty 1st team professional rugby league players competing in the European Super League participated in this study. Players were required to complete an incremental treadmill test, 5-minute run and 1200m ST over a two-week period in pre-season. MAS, peak heart rate (HRmax), peak lactate (Lapeak) and rating of perceived exertion (RPE) where collected upon completion of each test. Results demonstrated the 1200m ST to have a higher correlation for MAS than the 5-minute run (1200m ST: r = 0.73, 5-minute run: r = 0.64). However, when assessing validity using the level of agreement between data, the 5-minute run underreported MAS by 0.45 m·s-1 whereas the 1200m ST underreported MAS by 0.77 m·s-1. Ultimately, both field-based tests used in this study underreport MAS when compared to an incremental treadmill test, although the 5-minute run provides a closer agreement and therefore a more valid measurement for MAS than the 1200m ST.
从业者重视高速跑（HSR），以此来监测训练情况并满足比赛需求，同时试图使体能最大化并将受伤风险降至最低。从业者运用多种方法量化高速跑，比如绝对阈值、最大冲刺速度百分比以及最大有氧速度（MAS）。最近一项调查表明，在橄榄球联盟从业者中实施5分钟跑和1200米穿梭跑测试（ST），通过纳入最大有氧速度来量化高速跑。然而，这些方法在准确量化最大有氧速度方面的有效性尚不清楚。因此，本研究的目的是评估5分钟跑和1200米穿梭跑测试与最大有氧速度的金标准测量方法相比的有效性。20名参加欧洲超级联赛的一线职业橄榄球联盟球员参与了本研究。球员们被要求在季前赛的两周时间内完成递增式跑步机测试、5分钟跑和1200米穿梭跑测试。每次测试完成后收集最大有氧速度、最高心率（HRmax）、峰值乳酸（Lapeak）和主观用力程度分级（RPE）。结果表明，1200米穿梭跑测试与最大有氧速度的相关性高于5分钟跑（1200米穿梭跑测试：r = 0.73，5分钟跑：r = 0.64）。然而，在使用数据之间的一致性水平评估有效性时，5分钟跑低估最大有氧速度0.45米·秒-1，而1200米穿梭跑测试低估最大有氧速度0.77米·秒-1。最终，与递增式跑步机测试相比，本研究中使用的两种实地测试都低估了最大有氧速度，尽管5分钟跑提供了更接近的一致性，因此与1200米穿梭跑测试相比，对最大有氧速度的测量更有效。
