We aimed to a) introduce a new Test to Exhaustion Specific to Tennis (TEST) and compare performance (test duration) and physiological responses to those obtained during the 20-m multistage shuttle test (MSST), and b) determine to which extent those variables correlate with performance level (tennis competitive ranking) for both test procedures.
Twenty-seven junior players (8 males, 19 females) members of the national teams of the French Tennis Federation completed MSST and TEST, including elements of the game (ball hitting, intermittent activity, lateral displacement), in a randomized order. Cardiorespiratory responses were compared at submaximal (respiratory compensation point) and maximal loads between the two tests.
At the respiratory compensation point oxygen uptake (50.1 ± 4.7 vs. 47.5 ± 4.3 mL.min(-1).kg(-1), p = 0.02), but not minute ventilation and heart rate, was higher for TEST compared to MSST. However, load increment and physiological responses at exhaustion did not differ between the two tests. Players' ranking correlated negatively with oxygen uptake measured at submaximal and maximal loads for both TEST (r = -0.41; p = 0.01 and -0.55; p = 0.004) and MSST (r = -0.38; P = 0.05 and -0.51; p = 0.1).
Using TEST provides a tennis-specific assessment of aerobic fitness and may be used to prescribe aerobic exercise in a context more appropriate to the game than MSST. Results also indicate that VO2 values both at submaximal and maximal load reached during TEST and MSST are moderate predictors of players competitive ranking.
我们旨在：a）引入一项新的网球专项力竭测试（TEST），并将其表现（测试持续时间）和生理反应与20米多级往返跑测试（MSST）期间获得的结果进行比较；b）确定这两种测试程序中这些变量与表现水平（网球比赛排名）的相关程度。
法国网球联合会国家队的27名青少年球员（8名男性，19名女性）以随机顺序完成了MSST和TEST，其中TEST包含比赛元素（击球、间歇活动、横向移动）。在两次测试的次最大负荷（呼吸补偿点）和最大负荷下比较心肺反应。
在呼吸补偿点，与MSST相比，TEST的摄氧量更高（50.1±4.7 vs. 47.5±4.3 mL·min⁻¹·kg⁻¹，p = 0.02），但分钟通气量和心率没有差异。然而，两次测试之间的负荷增加和力竭时的生理反应没有差异。球员排名与TEST（r = -0.41；p = 0.01和-0.55；p = 0.004）和MSST（r = -0.38；P = 0.05和-0.51；p = 0.1）在次最大负荷和最大负荷下测得的摄氧量均呈负相关。
使用TEST可提供针对网球的有氧适能评估，并且可用于在比MSST更适合该运动项目的背景下进行有氧运动处方。结果还表明，TEST和MSST期间达到的次最大负荷和最大负荷下的VO₂值都是球员比赛排名的中度预测指标。
