本研究的目的是根据游泳的距离，在四种泳姿中，确定竞争性能和系绳力之间的关系，并分析力产生的相对值是否是比绝对值更好的游泳性能的决定因素。受试者（n = 32）进行了30秒的系留游泳全力以赴。在测试协议后的25天内，使用比赛的官方计时值在距离50，100和200 m处获得竞争性游泳速度。平均力量和速度（50米项目）显示出与爬泳（r = .92，p < .01）、仰泳（r = .81，p < .05）、蛙泳（r = .94，p < .01）和蝶泳（r = .92，p < .01）显著相关。这些数据表明，生产力的绝对值比相对值（标准化为身体质量）与竞争力表现更相关。绳系游泳试验是评价短距离竞技项目游泳运动员划水力量产生的可靠方法，也是评价短距离竞技项目运动员竞技能力的有效手段。
The purpose of the current study was to identify the relationships between competitive performance and tether forces according to distance swam, in the four strokes, and to analyze if relative values of force production are better determinants of swimming performance than absolute values. The subjects (n = 32) performed a 30 s tethered swimming all-out effort. The competitive swimming velocities were obtained in the distances 50, 100 and 200 m using official chronometric values of competitions within 25 days after testing protocol. Mean force and velocity (50 m event) show significant correlations for front crawl (r = .92, p < .01), backstroke (r = .81, p < .05), breaststroke (r = .94, p < .01) and butterfly (r = .92, p < .01). The data suggests that absolute values of force production are more associated to competitive performance than relative values (normalized to body mass). Tethered swimming test seems to be a reliable protocol to evaluate the swimmer stroking force production and a helpful estimator of competitive performance in short distance competitive events.
