This study described the kinematic variables of disabled swimmers’ performance and correlated them with their functional classification. Twenty-one impaired swimmers (S5–S10) performed 50-m maximum front-crawl swimming while being recorded by four underwater cameras. Swimming velocity, stroke rate, stroke length, intracycle velocity variation, stroke dimensions, hand velocity, and coordination index were analyzed. Kendall rank was used to correlate stroke parameters and functional classification with p < .05. Swimming velocity, stroke length, and submerged phase were positively correlated with the para swimmers functional classification (.61, .50, and .41; p < .05, respectively), while stroke rate, velocity hand for each phase, coordination index, and intracyclic velocity variation were not (τ between −.11 and .45; p > .05). Thus, some objective kinematic variables of the impaired swimmers help to support current classification. Improving hand velocity seems to be a crucial point to be improved among disabled swimmers.

这项研究描述了残疾游泳运动员表现的运动学变量，并将它们与他们的功能分类相关联。21 名受损游泳者 (S5-S10) 进行了 50 米最大前爬行游泳，同时被四台水下摄像机记录下来。分析游泳速度、划水率、划水长度、周期内速度变化、划水尺寸、手速和协调指数。Kendall 等级用于将卒中参数和功能分类与p  < .05 相关联。游泳速度、划水长度和潜泳阶段与准游泳运动员功能分类呈正相关（0.61、0.50 和 0.41；p < .05，分别为），而每个阶段的划水频率、速度手、协调指数和循环内速度变化不是（τ 在 -.11 和 .45 之间；p  > .05）。因此，受损游泳者的一些客观运动学变量有助于支持当前的分类。提高手速似乎是残疾游泳者需要提高的关键点。
