Biomechanical analysis of the skill of smash serve at the moment of collision with the ball in volleyball

الملخص

Volleyball has become one of the modern civil manifestations that reflects the progress of countries, the size of their sophistication and their interest in building the new player, in which the splendor of performance and the formulation of skills according to the biomechanical scientific foundations in order to reach accurate results that provide the most appropriate technical solutions with the economy of time and effort during the performance of volleyball skills, especially the skill of  smash serve reception, as a result of the proper use of scientific foundations in the study of movement based on the latest devices and means represented by imaging devices and kinetic analysis programs, which achieved objective accurate results in motor performance, added to volleyball skills in general and the smash serve reception , the distinctive and most exciting  biomechanical feature for the public in all international, Olympic and local forums.                                  The researchers concluded, through the conclusions, that the horizontal and vertical distances at the moment of collision directly affect the  smash serve reception , as it determines from where and when the player begins to perform the next stage and for any reason that leads to a shortcoming at the moment of collision.
