Biomechanics is one of the important sciences in physical education in general and athletic achievement in particular, as it is a science that performs general analysis of different human movements and knowledge of good techniques for them. The study aimed to Identifying the effect of training using competitive exercises to develop some types of shooting according to some bio-kinematic variables of the group for the youth basketball category.

The researcher used the experimental method with one group for its suitability in solving the research problem and achieving its objectives. The sample was selected in a deliberate manner, represented by the players of Al-Ghadriyah Sports Club, the youth category, whose number is (8) players (corner) out of 24 players. Pre tests were conducted on 1/9/2022 and the main experiment on 2/9/2022 and ended on 2/11/2022, as for the post-test on 3/11/2022 at the Al-Ghadriyah Sports Club in Kerbala Governorate. A video camera was used during the experiment, and a program for analyzing mathematical skills (Dartfish) was also used to extract kinematic variables, and after processing the data with a computer according to the SPSS Ver 10 statistical program, the researcher concluded that the exercises used and applied in the training method using competitive exercises had a role in developing some kinematic variables related to developing the accuracy of shooting by free throws and shooting calculated by three points for the players of the distributor position in basketball. Also, some kinematic variables were developed to perform the free throw shooting, which are (maximum flexion angle of the knee joint, maximum flexion angle of the hip joint, maximum height of the ball in the air (maximum vertical distance), angle of the ball starting, angle of entry of the ball). The most important recommendations are: Adopting training using competitive exercises applied in the planned training program to develop free-throw shooting and long-range shooting calculated by three points in the training curricula for the players of the corner position in basketball. And the use of skill exercises according to the biomechanical variables according to the different playing centers (distributor - corner - pivot) because of their impact on providing effort (for the coach and the player) and addressing errors that may appear within the training units.
