: Estimating race times for open-water swimming based on pool swimming times could be useful for talent identification and training optimisation. We aimed to compare the swimming speeds of the world's top and other swimmers in the 2023 Aquatics Championship men's 10 km OWS race. : Sixty-five swimmers were divided into four groups: G1 (1st-10th positions), G2 (11st-30th positions), G3 (31st-47th positions), and G4 (48th-65th positions). Swimming speed, stroke frequency (SF), and stroke length (SL) for each lap (laps 1-6) were recorded. Critical speed (CS) was calculated from each participant's personal best times in the 400, 800, and 1500 m freestyle events in the pool. Swimming speed against CS was calculated (%CS). : The top performance group (G1) maintained their swimming speed from beginning (lap 1, 1.53 m/s) to end (lap 6, 1.50 m/s), at 92.7 ± 1.9% of CS, characterised by longer SL (1.26 m) and lower SF (72.86 rpm). G3 and G4 were unable to maintain their swimming speed, which decreased from G3: 97.64 ± 1.62% and G4: 96.10 ± 1.96% of CS at lap 1 to G3: 88.39 ± 3.78% and G4: 85.13 ± 5.04% at lap 6. This reduction in swimming speed is consistent with the increased reliance on anaerobic metabolism reported in previous studies under similar conditions. : Race pacing for maintaining speeds of 92%CS throughout the race could be an important resilient index in open-water swimming. %CS might be a useful index for estimating the athletic performance level in open-water swimming.
根据泳池游泳时间估算公开水域游泳的比赛时间，这对于人才识别和训练优化可能是有用的。我们旨在比较2023年游泳锦标赛男子10公里公开水域游泳比赛中世界顶级选手和其他选手的游泳速度。65名游泳运动员被分为四组：G1（第1 - 10名）、G2（第11 - 30名）、G3（第31 - 47名）和G4（第48 - 65名）。记录了每一圈（第1 - 6圈）的游泳速度、划频（SF）和划幅（SL）。临界速度（CS）根据每位参与者在泳池400米、800米和1500米自由泳项目中的个人最佳成绩计算得出。计算相对于CS的游泳速度（%CS）。顶级表现组（G1）从开始（第1圈，1.53米/秒）到结束（第6圈，1.50米/秒）保持游泳速度，为CS的92.7±1.9%，其特点是划幅较长（1.26米）且划频较低（72.86转/分钟）。G3和G4无法保持他们的游泳速度，从第1圈时G3为CS的97.64±1.62%、G4为CS的96.10±1.96%下降到第6圈时G3为CS的88.39±3.78%、G4为CS的85.13±5.04%。这种游泳速度的下降与先前研究报道的在类似条件下对无氧代谢的依赖增加相一致。在整个比赛中保持92%CS速度的比赛配速可能是公开水域游泳中一个重要的耐力指标。%CS可能是估算公开水域游泳运动表现水平的一个有用指标。
