A Predictive Statistical Model in the Light of some Biomechanical Indicators for Shot Put Players

The research aims to arrive at a predictive statistical model in the light of some biomechanical indicators of the shot put players. This is achieved through: identifying the correlation between some of the biomechanical indicators of the shot put players, identifying the proportions of the contribution of the biomechanical indicators in the digital level of the shot put players, arriving at predictive equations based on some biomechanical indicators in the shot put, the researcher used the descriptive approach and the sample of the research was better (4) players in the shot put in terms of the digital level. Filming was done at the Faculty of Physical Education, Kafr El-Sheikh University, on 10/28/2019, with (12) attempts, and the performance of the players was photographed and analyzed to extract the biomechanical variables and measure the digital level, and through transactions. The following statistical results were obtained: The presence of indicators for the moment of the beginning of the thrust phase: the resultant force, acceleration, velocity of the center of gravity of the body, the result of the wheel, the momentum of the center of gravity of the right leg thigh, the resultant velocity of the center of gravity of the humerus of the thrusting arm, the amount of movement of the center of gravity of the forearm of the thrust arm Momentum of movement for the humeral center of gravity of the thrusting arm, indicators that contributed to the mid-phase moment of the thrust: Momentum of movement of the center of gravity of the trunk, the resultant force, the amount of movement of the center of gravity of the right leg thigh, the result of the acceleration of the center of gravity of the humerus The thrust arm, the resultant force of the center of gravity of the body, the resultant velocity of the center of gravity of the forearm of the thrust arm, indicators that contributed to the moment of disposal in the thrust of the shot: the amount of movement, the net acceleration of the center of gravity of the trunk, the net acceleration of the center of gravity of the thrust arm humerus, the result of the wheel for the center of gravity of the right leg leg, The resultant velocity, the net force of the center of gravity of the body, the net force of the center of gravity of the right thigh.
