Objective: This study aims to examine the shuffle performance and asymmetry across different angles and directions among collegiate basketball players. Methods: Forty-two players completed six randomized shuffle tests at two directions (left/right) and three angles (45°/90°/135°). The shuffle asymmetry index was calculated as (dominant – non-dominant) / dominant × 100% . Two-way repeated-measures ANOVA and Kruskal-Wallis tests were used to analyze shuffle performance and asymmetry in different angles. Kappa coefficient evaluated directional asymmetry consistency. Results: Results showed excellent reliability across conditions (ICC = 0.94 – 0.97; CV = 2.4 – 3.2%). A significant main effect of angle (F = 12.334, p < 0.001) and an angle × direction interaction (F = 14.489, p < 0.001) were observed. Left‐ward shuffles at 135° (2.76 ± 0.31) were slower than at 45° and 90° (all p < 0.001), whereas right‐ward performance did not differ by angle (p > 0.05). No significant difference in the asymmetry of shuffle from different angles (χ² = 2.103, p = 0.349; mean 5.1 – 6.6%), and kappa coefficients indicated poor consistency of directional dominance (k = 0.077 – 0.168). Conclusion: The shuffle performance was jointly influenced by angle and direction. The magnitude of shuffle asymmetry remained consistent across angles, suggesting that movement asymmetry was task-dependent rather than fixed. These findings support the implementation of multi-angle shuffle in training and evaluation protocols to enhance performance.
