Abstract
The current study aims at Identify biomechanical indicators discriminating the performance of using arms and without using arms in the vertical pushing as the basis of designing a training program, through: Identifying the biomechanical variables using and without using arms in the vertical pushing, Identifying the biomechanical indicators discriminating the performance by using and without arms in the vertical pushing, The two researchers used the descriptive method, And the research sample of the first-team of Tanta and KafrelSheikh Sports Clubs, it included on (8) of players, were selected as follows: 2 Volleyball players, 2 basketball players, 2 football players, 2 high jump players, The results showed: using of arms in the vertical pushing led to increased pushing distance, and the contributing percentage of the arms (29.84%), and there are discriminating indications by using the Force Platform in the resultant of pushing Force for the two moments of beginning and the end of the damping for the benefit of performance of using arms. There are biomechanical indications that discriminate of the vertical pushing at the moment damping begins without using arms, in: Momentum of the gravity center of foot segment and angular displacement of the head with the trunk. There are biomechanical indications discriminating in vertical pushing by using arms: Momentum of the gravity center of forearm segment, Elbow angular velocity for the moment damping begins, Resultant Force of the gravity center of forearm segment, Momentum of the gravity center of body the moment damping ends. Resultant velocity of the gravity center of forearm segment, Momentum of the gravity center of body the moment pushing begins, Resultant Force of the center of gravity of forearm segment, Momentum of the center of gravity of foot segment at the moment pushing ends, Resultant Force and Momentum of the center of gravity of forearm segment at the moment hopping begins, momentum of the center of gravity of forearm segment, Resultant Force of the gravity center  of trunk segment at the maximum height.
