To (1) compare the pacing strategies of different-level open-water swimmers during the 10-km race of the FINA 2015 Swimming World Championships and (2) relate these pacing strategies to the race performance.
Final and intermediate split times, as well as intermediate race positions, from the 10-km race participants (69 men and 51 women) were collected from the public domain and were divided into 5 groups (G1-G5) depending on their finishing positions.
Medalists and finalists (G1 and G2, respectively) presented an even pacing profile with swimming velocities similar to those of the less successful swimmers (G3-G5) on the initial and middle stages of the race but a 1.5-3% increase in swimming velocity in the last quarter of the race. This acceleration toward the end of the race, or "end spurt," was largely related to the race performance and was not observed in the G3 and G4 (even-paced profile) or G5 (positive pacing profile) groups. Intermediate race positions and lap rankings were negatively related to finishing position, indicating a delayed positioning of the most successful swimmers at 25%, 50%, and 75% of race distance.
The adoption of a conservative starting strategy by open-water swimmers with a negative pacing profile and delayed partial positioning seems to increase the chances of overall race success, as it allows a fast end spurt that is closely related to successful finishing race positions.
（1）比较不同水平的公开水域游泳运动员在 2015 年国际泳联世界锦标赛 10 公里比赛中的配速策略，（2）将这些配速策略与比赛表现相关联。
从公开领域收集了 10 公里比赛参与者（69 名男子和 51 名女子）的最终和中间分段时间，以及中间比赛位置，并根据他们的完赛位置将其分为 5 组（G1-G5）。
奖牌获得者和决赛选手（G1 和 G2）在比赛的初始和中间阶段呈现出均匀的配速模式，游泳速度与不太成功的游泳运动员（G3-G5）相似，但在比赛最后四分之一段的游泳速度提高了 1.5-3%。这种比赛结束时的加速，或“冲刺”，在很大程度上与比赛表现有关，在 G3 和 G4（均匀配速模式）或 G5（正配速模式）组中没有观察到。中间比赛位置和单圈排名与完赛位置呈负相关，表明最成功的游泳运动员在比赛的 25%、50%和 75%处的位置会延迟。
采用消极配速模式和延迟部分定位的公开水域游泳运动员采取保守的出发策略，似乎增加了整体比赛成功的机会，因为这允许快速冲刺，这与成功的完赛位置密切相关。
