Basketball tests assessing dribbling speed predicated on total performance times are influenced by sprinting speed. This study examines an approach termed Dribble Deficit to counter this limitation by examining the relationships between sprinting and dribbling speed during linear and change-of-direction (COD) tasks measured using total performance time and Dribble Deficit. Ten semi-professional basketball players completed linear sprints and COD sprints with and without dribbling. Dribble Deficit was calculated as the difference between the best time for each dribbling trial and corresponding non-dribbling trial for linear and COD sprints. Large to very large significant relationships (P < 0.05) were evident between linear sprint and dribble times (R = 0.64-0.77, R = 0.41-0.59), and between COD sprint and dribble times (R = 0.88, R = 0.77). Conversely, trivial-small relationships were evident between linear sprint time and linear Dribble Deficit (R = 0.01-0.15, R = 0.00-0.02). A non-significant, moderate, negative relationship was observed between COD sprint time and COD Dribble Deficit (R = -0.45, R = 0.20). These findings indicate Dribble Deficit provides a more isolated measure of dribbling speed than tests using total performance times. Basketball practitioners may use Dribble Deficit to measure dribbling speed independent of sprint speed in test batteries.
篮球测试评估运球速度，基于总表现时间，受冲刺速度的影响。本研究通过检查线性和变向（COD）任务中的冲刺和运球速度之间的关系，检验了一种称为运球缺陷的方法，以克服这种局限性，该方法使用总表现时间和运球缺陷来测量。10 名半职业篮球运动员完成了带有和不带有运球的线性冲刺和 COD 冲刺。运球缺陷是每个运球试验的最佳时间与线性和 COD 冲刺的相应无运球试验之间的差值。线性冲刺和运球时间之间存在着非常大的显著关系（P < 0.05）（R = 0.64-0.77，R = 0.41-0.59），COD 冲刺和运球时间之间也存在着非常大的显著关系（R = 0.88，R = 0.77）。相反，线性冲刺时间和线性运球缺陷之间存在着微不足道的小关系（R = 0.01-0.15，R = 0.00-0.02）。COD 冲刺时间和 COD 运球缺陷之间存在着非显著的、中等的、负相关关系（R = -0.45，R = 0.20）。这些发现表明，与使用总表现时间的测试相比，运球缺陷提供了一种更孤立的运球速度测量方法。篮球运动员可能会在测试组合中使用运球缺陷来测量与冲刺速度无关的运球速度。
