This study aimed to identify the relationship between dryland tests and swimming performance in elite Paralympic swimmers. Fifteen competitive swimmers (age: 27.4 ± 5.4 years, height: 1.70 ± 6.8 m, body mass: 67.9 ± 9.2 kg; 9 males, 6 females) performed a lat pull-down and a bench press incremental load test to determine maximum power (Pmax), the strength corresponding to maximum power (F@Pmax), and the barbell velocity corresponding to maximum power (V@Pmax) from the force-velocity and power-velocity profiles. These outcomes were also normalized by the athlete's body mass. Swimming performance was carried out from the best result in a 100 m freestyle race registered during an international competition. Lat pull-down F@Pmax was significantly associated with 100 m freestyle chronometric time ( = -0.56, < 0.05), and lat pull-down V@Pmax presented a relationship with mean swimming velocity ( = 0.71, < 0.01). Similarly, bench press F@Pmax and the normalized F@Pmax were significantly related to the mean swimming velocity ( = -0.51, = -0.62, < 0.05). Stepwise multiple regression showed that lat pull-down V@Pmax, bench press normF@Pmax, and V@Pmax accounted for 40.6%, 42.3%, and 65.8% ( < 0.05) of the mean swimming velocity variance. These preliminary results highlighted that simple dryland tests, although with a moderate relationship, are significantly associated with 100 m freestyle swimming performance in elite Paralympic swimmers.
本研究旨在确定残奥会优秀游泳运动员的旱地测试与游泳成绩之间的关系。15名竞技游泳运动员（年龄：27.4±5.4岁，身高：1.70±6.8米，体重：67.9±9.2千克；9名男性，6名女性）进行了下拉和卧推递增负荷测试，以从力-速度和功率-速度曲线中确定最大功率（Pmax）、对应最大功率的力量（F@Pmax）以及对应最大功率的杠铃速度（V@Pmax）。这些结果也通过运动员的体重进行了标准化。游泳成绩根据国际比赛中记录的100米自由泳比赛的最佳成绩得出。下拉F@Pmax与100米自由泳计时成绩显著相关（r = -0.56，p < 0.05），下拉V@Pmax与平均游泳速度呈相关关系（r = 0.71，p < 0.01）。同样，卧推F@Pmax和标准化F@Pmax与平均游泳速度显著相关（r = -0.51，r = -0.62，p < 0.05）。逐步多元回归显示，下拉V@Pmax、卧推标准F@Pmax和V@Pmax分别解释了平均游泳速度方差的40.6%、42.3%和65.8%（p < 0.05）。这些初步结果表明，简单的旱地测试虽然相关性中等，但与残奥会优秀游泳运动员的100米自由泳成绩显著相关。
