The mechanical analysis of long-range shooting and its relation to the ball's flight speed at the moment it reaches the target using a handball shooting machine.

Abstract

The current research aims to design a device (Sport Electro) to measure the speed of the ball at the moment it reaches the target, as well as to identify the speed of the ball at the moment it reaches the target using the (Sport Electro) device. Additionally, it aims to identify some biomechanical variables in long-range shooting from outside the 9-meter area, in order to understand the relationship between some biomechanical variables during shooting from a jump and the speed of the ball's flight at the moment it reaches the target.  The researchers hypothesized the capability of the Sport Electro device to measure the shooting speed from a high jump.Handball, and there is a statistically significant relationship between the biomechanical variables and the speed of the ball at the moment it reaches the target. The researchers used the descriptive method with the correlational approach due to its suitability for the nature of the problem and the research objectives. The research community consisted of advanced handball players in Nineveh Governorate, numbering twenty players, from which five players were intentionally selected who use the right arm for shooting. The researchers also used the statistical package (SPSS) and applied the relevant statistical laws: mean, standard deviation, and simple correlation coefficient (Pearson). The researchers concluded the following:

1. The device (Sport Electro) achieved its intended purpose through the necessary readings of the ball's shooting speed towards the goal, which were characterized by precise data recording.

 -2Through the research results, it was found that the members of the research sample fluctuated in the correlation value, sometimes approaching significance and at other times moving away from significance for the other study variables.
