Background: Good change-of-direction sprint performance is considered important for basketball players. Regarding the components of a change-of-direction task, a correlation between the linear sprint and concentric power output can be assumed. Previous studies have shown heterogeneous correlation coefficients between different change-of-direction (COD) tests and linear and jump performance. Methods: Therefore, 47 trained youth basketball players (13.2 ± 3.6 years; 34 males and 13 females) were recruited. Linear sprint (10 and 20 meters), squat jump, and COD sprint tests (the zig-zag test and triangle test) were conducted. One-tailed Pearson correlation analysis was used to assess the relationship of sprint and jump performance with COD tests, and two-tailed analysis was used to assess the relationship between the different COD tests. Results: This study showed that both linear sprint variables and concentric power output explained the variance in the different COD tests in a homogeneous manner (r2 = 0.14 to 0.42). The correlation coefficients did not statistically differ between the male and female players, and the different COD tests correlated moderately with one another (r2= 0.42 – 0.46). For both analyses, the intercorrelation results did not differ significantly between sexes and analyzed correlation coefficients. Conclusion: It is recommended that the squat jump, 10to 20 meter linear sprint, zig-zag and triangle tests are included in batteries of tests conducted in youth basketball players. COD tests with the same structure may have similar physiological requirements; however, these tests have task-specific characteristics. Therefore, coaches and sport scientists must review and select different tests with logical validity based on sport-specific requirements.
