优秀游泳运动员的配速策略一直以平均圈速为特征。在本研究中，我们研究了200米世界级游泳运动员的比赛策略，他们的水下和表面圈组件。2013年世界游泳锦标赛（西班牙巴塞罗那）200米比赛的决赛和半决赛通过创新图像处理系统（InThePool（R）2.0）进行了分析。优秀游泳运动员的自由泳速度在整个200米比赛圈中通常会下降（-0.12米）。s（-1），95% CI -0.11至-0.14 m . s（-1），P=0.001，eta（2）=0.81），而水下速度，这是比自由游泳，没有意义的影响，由比赛的进展（0.02米。s（-1），-0.01 ~0.04 m . s（-1），P=0.01，eta（2）=0.04）。当在水下游泳时，优秀游泳运动员通常从比赛的第一圈到第三圈的距离较少（-0.66 m，-0.83至-0.49 m，P=0.001，eta（2）=0.34），尽管在仰泳和蝶泳比赛中保持水下距离。这些策略使游泳运动员在最后一圈保持他们的平均速度，尽管自由泳速度下降。建议优秀教练和游泳运动员通过考虑水下和水面比赛组件来模拟他们的比赛策略。
Pacing strategies of elite swimmers have been consistently characterised from the average lap velocities. In the present study, we examined the racing strategies of 200 m world class-level swimmers with regard to their underwater and surface lap components. The finals and semi-finals of the 200 m races at the 2013 World Swimming Championships (Barcelona, Spain) were analysed by an innovative image-processing system (InThePool (R) 2.0). Free swimming velocities of elite swimmers typically decreased throughout the 200 m race laps (-0.12 m . s(-1), 95% CI -0.11 to -0.14 m . s(-1), P=0.001, eta(2)=0.81), whereas underwater velocities, which were faster than free swimming, were not meaningfully affected by the race progress (0.02 m . s(-1), -0.01 to 0.04 m . s(-1), P=0.01, eta(2)=0.04). When swimming underwater, elite swimmers typically travelled less distance (-0.66 m, -0.83 to -0.49 m, P=0.001, eta(2)=0.34) from the first to the third turn of the race, although underwater distances were maintained on the backstroke and butterfly races. These strategies allowed swimmers to maintain their average velocity in the last lap despite a decrease in the free swimming velocity. Elite coaches and swimmers are advised to model their racing strategies by considering both underwater and surface race components.
