The limbs of the human are composed by several segments that make task performance possible. In daily life, juman have to properly control and coordinate many degrees of freedom that produce by interlimbs and intersegments to achieve performance goal. The many problems of handling degrees of freedom, coordination, during the learning procedure will affect the movement performance. If the degrees of freedom were manipulated during the learning process of a new discrete movement, will it affect the movement performance? A-B-A design of Single Subject Research technique was utilized. Participant (N=1,age=24) practiced a dart throwing with non-dominant arm as a novel task. Degrees of freedom of the non-dominant arm were the independent variable and the performance outcome, in terms of movement accuracy, was the dependent variable. With three blocks contain 200 throwing trails, 50 trails of natural throwing form (A1); 100 trails of the throwing form with stabilizing the degrees of freedom at shoulder (B); and 50 trails of natural throwing form again (A2); Results showed that scores of blocks in A1 kept steady; in block B the scores showed a plsitive change, and kept stable until end of block B; in A2 the scores kept the level as B, and didn't have much change. Overall, the findings supported the hypothesis that by reducing the degrees of freedom during the learning process of a new discrete movement improves the motor performance.
