The Effect of Fatigue on Free Throw Kinematic Movement in Basketball

—Free throw is a shoot that is done because it gets a foul on when entering the ball towards the ring with the value in one shoot is one. This study aims to determine the relationship and contribution of Centre of mass, angle of elbow joint, angular velocity of elbow joint, angle of wrist joint, angular velocity of wrist joint, release height of the ball, angle release of ball and angle release of upper arm against free throw throws that are affected by the fatigue condition. The method used in this study is a correlational descriptive, a sample of 10 player aged 16-18 years. Kinematic analysis used by kinovea software, Fastec high speed camera 32GB HDR-PJ540 camera, polar heart rate monitor watch and RAST test, data analysis using SPSS version 20 with correlation and regression analysis testing. The results of this study concluded from eight indicators only one that has a significant relationship and contribution to the result of free throw throw is angular velocity of wrist joint. The conclusion of this research is that it can be used as a reference for the science of coaching that how important to train movement basketball athlete in free throw at the condition of fatigue.
