Abstract :The aim of this study is to analyze kinematical variables of discus throw activity in Para-Athletics F57 and to investigate their relationships with digital level achievement. International Para-athlete `Saifi Nassima` participated voluntarily in this study. The athlete throwed the discus with her right arm. Recordings were made by synching cameras insert ignore into journalissuearticles values(AEE MagicCam, 170° view, MOV Format Video, 720p Video Resolution, 120 ips NTFS, Screen Resolution 1280*720 16:9); for side and rear views by a LANC insert ignore into journalissuearticles values(CONTROL-L); device. The athlete wore reflective markers to track their motions on joints of the wrists, the elbows, the shoulders, the hip center, and down the neck with the least possible number of occlusions, to analyze the length and angle of movement by the x and y axis. The best six throws during the first and second phases insert ignore into journalissuearticles values(start and finish throwing); of the discus throw were included for analysis in two-dimensional by Dartfish.9 software. Means, standard deviations, minimum and maximum values were applied as descriptive statistics, and Pearson test for the correlations between all variables. As a result, there was a positive significant correlation of digital level with cubitus angle of the throwing hand insert ignore into journalissuearticles values(p< .001);, trunk angle insert ignore into journalissuearticles values(p< .005); in the first phase, and with disk flight time insert ignore into journalissuearticles values(p< .005);, throwing angle insert ignore into journalissuearticles values(p< .001); in the second phase. In conclusion, we confirm that the increase in the values of the variables of distance shot from the armrest, and the wrist angle of the shooting hand in the first phase of throwing, affects the digital level achievement. The decrease in the value of the throwing angle variable in the second phase of throwing affects the digital level achievement.
