In a recent article by Schnitzler, Seifert, and Chollet (2011), they used an index of coordination (IdC) to quantify arm synchronization in swimming, which has become a practical standard to measure gaps (negative IdC) and overlaps (positive IdC) in arm propulsion. Their previous work supported an increase in IdC as swimming velocity and performance level increase, consistent with mechanics and physiology. Their recent study showed a lower IdC for expert swimmers than for recreational swimmers and concluded "catch-up coordination can be an efficient coordination mode. "In the hopes of preventing coaches and swimmers from using this finding to justify "catch-up stroke", other explanations are suggested.
在 Schnitzler、Seifert 和 Chollet（2011）最近的一篇文章中，他们使用协调指数（IdC）来量化游泳中的手臂同步，这已成为衡量手臂推进中间隙（负 IdC）和重叠（正 IdC）的实用标准。他们之前的工作支持 IdC 随着游泳速度和表现水平的提高而增加，这与力学和生理学一致。他们最近的研究表明，与休闲游泳者相比，专业游泳者的 IdC 较低，并得出结论“追赶协调可以是一种有效的协调模式。”为了防止教练和游泳者利用这一发现来证明“追赶划水”是合理的，提出了其他解释。
