The purpose of this study was to evaluate the relationship between: 1) laboratory-determined cycling peak oxygen consumption (VO ) and AS performance in a new underwater swim test (UWST), and 2) cycling VO and ventilatory threshold (VT) in cycling and performance score during a simulated AS solo routine. Trained artistic swimmers (n=15, 15.8±0.8 yrs., height: 169.1±5.4 cm, body mass: 57.1±6.3 kg) completed (1) a maximal incremental cycle test to exhaustion to determine VO , (2) the UWST which comprised 275 m of freestyle and underwater breaststroke, and (3) a simulated solo competition where artistic swimming elements were evaluated by five FINA judges. There was a significant correlation between mean element score and (i) VO (48±4 mL kg min , r=0.44, =0.05), and (ii) UWST (r=-0.64, =0.005). However, there was an insignificant relationship between cycling ventilatory threshold and mean element score (r=-0.36, =0.10). In addition, the results demonstrate a significant relationship between HR at the ventilatory threshold and peak HR of the UWST (r=-0.64, =0.014). The results of this study demonstrate that VO is an important determinant of AS performance. In addition, the UWST appears to be a useful indicator of AS performance.
1）实验室测定的自行车运动峰值耗氧量（VO₂）与一项新的水下游泳测试（UWST）中的花样游泳表现，以及2）自行车运动VO₂与自行车运动中的通气阈值（VT）以及模拟花样游泳单人套路中的表现得分。训练有素的花样游泳运动员（n = 15，15.8±0.8岁，身高：169.1±5.4厘米，体重：57.1±6.3千克）完成了：（1）一项递增负荷至力竭的自行车测试以确定VO₂，（2）包括275米自由泳和水下蛙泳的UWST，以及（3）一场模拟单人比赛，由五名国际泳联裁判对花样游泳动作进行评分。平均动作得分与（i）VO₂（48±4毫升·千克⁻¹·分钟⁻¹，r = 0.44，P = 0.05），以及（ii）UWST（r = -0.64，P = 0.005）之间存在显著相关性。然而，自行车运动通气阈值与平均动作得分之间的关系不显著（r = -0.36，P = 0.10）。此外，结果表明通气阈值时的心率与UWST的心率峰值之间存在显著关系（r = -0.64，P = 0.014）。本研究结果表明，VO₂是花样游泳表现的重要决定因素。此外，UWST似乎是花样游泳表现的一个有用指标。
