Effect of Corrective Exercises by an Innovative Device According to Some Biomechanical Variables in the Thrust of the Aiming Arm and the Accuracy of the Free Throw Correction for Basketball Players

Abstract

          Through the researchers' interest in the basketball game and the continuous follow-up of the matches of the Iraqi club championships, the researcher found that there is a problem embodied about the poor accuracy of shooting from the free throw from a distance (225.4 m) from the free throw line to the center of the throat, and the researchers attribute the reason for this to the lack of use innovative and modern devices and tools and the optimal use of laws and biomechanical foundations and their investment in discovering the strengths and weaknesses of the aiming arm, especially the fingers pointing to the ball to improve the free throw shooting of basketball at ages (under 18 years) in addition to the presence of some technical errors associated with the performance of the skill, therefore, the researchers decided to study free throwing in basketball and diagnose technical errors in the biomechanical variables (kantec) of the movement of the arm and the fingers of the aiming hand at the moment of the exit of the ball in the research sample through the creation of a palm device to measure the compressive force from the fingers of the hand to the arm aiming the ball, and the development of corrective exercises in light the biomechanical variables to improve the level of performance of this skill and the precise mechanical details and knowledge of its causes are what lead to the improvement of this skill and it is an important and necessary requirement to acquire the correct kinematic course and ideal accuracy in hitting the ball in the throat of the basket to achieve the best performance.          The study also aimed to: Creating a device to measure the strength and time of the aiming arm while aiming with a basketball, as well as identifying the biomechanical variables of the shooting skill in the free throw of basketball players, and the development of corrective exercises according to some biomechanical variables for the skill of correction, the free throw of the basketball.          The researchers also used the experimental method, and the research experiment was conducted on a community of young players of (under 18) years of age for the basketball club Hilla with a sample (n = 5) and the researcher gave each player (10) attempts to shoot with a free throw from a distance of (4.225 m) consequently, the total attempts are (50) attempts in the pre-test. The exercises lasted (6) weeks, at an average of (4) units per week using the interval training method, and the corrective unit time was (35%) from the beginning of the main part assigned by the team coach.
