Abstract: The physical superiority of the player in the level of his performance of the basic offensive skills, including shooting by jumping forward and high, does not depend on the development of physical and skill capabilities only, but is linked to the biochemical variables characteristic of performance, which are approach speed, flight speed and flight time in addition to that momentary force, i.e. the amounts of force exerted in one step of While using the (DYNA FOOT) device.Which gives real indicators in terms of strength, time and speed during the movement of the movement through the stages of running the distance and mastering the correct movement path to other parts to achieve the mechanical goal of the skill of correction, which is to score a goal with all speed and accuracy, and by following the researcher to most of the training units for handball players it became clear there Lack of training related to biochemical variables, which is reflected in the level of players ’performance, which affects the nature of performance and accuracy of shooting.The objective of the research is to prepare and recognize the effect of physical exercises using the (DYNA FOOT) device. In developing some biochemical variables and the skill of shooting by jumping in front - high with handball emerging, the researcher used the experimental method of experimental design with pre and posttest for the two equal groups (experimental and control) to suit the nature of the research.The research community was identified with handball players (Specialized School for Gifted People of the Ministry of Youth and Sports) of ages (14-15) years for the 2019 training season, which amounted to 16 players. As the research sample was selected using the comprehensive inventory method, the sample was divided into two groups (experimental and control) with seven players for each group.The most important conclusions were the results of a remarkable development between the preand post-measurement in the development of some biochemical variables and the skill of shooting by jumping in front - high with the handball youth for the experimental group and in favor of the post-measurement.
