To determine the relationship between outcomes of the shuttle wheel test (SWT) and peak oxygen uptake (VOpeak) during that test and whether SWT and VOpeak can discriminate between different skill levels of wheelchair tennis players.
Fifteen wheelchair tennis players performed an SWT on a tennis court while VO was measured continuously. Outcome measures were VOpeak and achieved stage. Relations between outcomes and Dutch wheelchair tennis ranking were calculated with Spearman correlation. Independent t tests were used to test for differences between national and international players.
Moderate correlations were found between VO2peak and SWT outcome (r = .40-.47). The tennis ranking correlated weakly with VOpeak (r = -.35) and strongly with SWT outcome (r = -.80). A significant difference was found between national and international players for achieved stage (P = .027) and VOpeak (P = .027).
The SWT outcome only explained a small part of the variance in VOpeak among players, so it cannot be considered a valid test for aerobic capacity. However, SWT outcomes are related to the skill level of the player and give a good indication of the overall peak wheelchair performance.
确定穿梭跑测试（SWT）结果与该测试期间的峰值摄氧量（VOpeak）之间的关系，以及SWT和VOpeak是否能够区分不同技能水平的轮椅网球运动员。
15名轮椅网球运动员在网球场上进行SWT，同时持续测量VO。结果指标为VOpeak和达到的阶段。使用Spearman相关性分析计算结果与荷兰轮椅网球排名之间的关系。采用独立t检验来检验国内和国际运动员之间的差异。
发现VO2peak与SWT结果之间存在中等程度的相关性（r = 0.40 - 0.47）。网球排名与VOpeak弱相关（r = -0.35），与SWT结果强相关（r = -0.80）。在达到的阶段（P = 0.027）和VOpeak（P = 0.027）方面，国内和国际运动员之间存在显著差异。
SWT结果仅解释了运动员VOpeak差异的一小部分，因此不能将其视为有氧能力的有效测试。然而，SWT结果与运动员的技能水平相关，并能很好地反映轮椅运动的总体峰值表现。
