Abstract

The importance of the research was represented in a three-dimensional kinematic analysis of the instantaneous speed of the ball, as well as calculating the potential energy from the height of the body’s center of gravity, and finding the relationship between each of the potential energy and the three components of instantaneous speed. As for the research problem, it is that studies in the field of biomechanics lack live applications for many topics, including the topic of potential energy. The researchers used the descriptive approach in the style of correlational studies because it suits the nature and problem of the research. The results of this study showed an important correlation between the potential energy, the lateral and vertical speeds of the ball, and the resultant speed of the diagonal Spiking in volleyball this means that the greater the potential energy of the player, the greater the lateral and vertical speeds of the ball at the moment of hitting the ball. This is due to the transformation of potential energy into kinetic energy at the moment of contact, which leads to a faster and stronger spiking . The researchers concluded that the instantaneous speed of the ball depends on both the potential energy and the direction of the spiking blow. Thus, researchers recommend that coaches should focus on developing the potential energy of female players in order to improve the speed and strength of their spiking blows. The potential energy can also be improved by including jumping exercises in training programs.
