چکیده
|
The present study analyzed the effect of increased distance on basketball jump shot outcome and performance. ten male expert basketball players were filmed and a number of kinematic variables analyzed during jump shot that were performed from three conditions to represent close,intermediate and far distances (2.8,4.6,and 6.4m,respectively). shot accuracy decreased from 59% (close) to 37% (far),in function of the task constraints (p < 0.05). ball release height decreased (p < 0.05) from 2.46 m (close) to 2.38m (intermediate) and to 2.33m (long). release angle also decreased (p < 0.05) when shot was performed from close (78.92°) in comparison to intermediate distances (65.60°). while,ball release velocity increased (p < 0.05) from 4.39 m/s (close) to 5.75 m·s -1 (intermediate) to 6.89 m·s -1 (far). these changes in ball release height,angle and velocity,related to movement performance adaptations were suggested as the main factors that influence jump shot accuracy when distance is augmented. © journal of sports science and medicine.
