A comparative study using (VDCD – Cuter) and (AutoCAD) programs to analyze the skill of hitting the forehand smash in volleyball for female players at Al Amana Sports Club

Abstract

      The importance of using offensive skills in volleyball is increasing, as they are decisive in scoring points, in which performance is required to be governed by biomechanical characteristics that are the primary determinant of the success of the skill. Among these skills is the crushing skill, which is characterized by players who have biomechanical variables in steps, rising, and hitting to reach the highest height. When hitting the ball through approach speed and jumping agility, which cannot be measured except through the use of many electronic programs such as (VDCD - Cuter), (AutoCAD), through which these biomechanical variables can be measured, and compared with the scientific model, in addition to the accuracy of directing the ball to the ball. The opponent's court and implementing it well by saving effort and achieving the desired goal. These requirements require the striking player to have a level of motor performance higher than the opposing blocking wall and perform faster than it to overcome it and thus achieve the goal of the skill.

     Hence the importance of the research, as the researcher sought to study the most important biomechanical variables for performing the frontal smash through the programs (VDCD - Cuter) and (AutoCAD) compared with the global model to access the variables to achieve the ability to control and control muscular work, and this is done through During the study of the parts of the skill (approaching, rising, hitting, landing) of the confronting smasher.

  The problem of the research lies in the weakness of the technical performance of the crushing blow of the female players and the decline in the level of performance, especially if we know that the female players possess appropriate physical characteristics. If these characteristics are exploited in conjunction with the mechanical principles and laws that limit movement, then the aspect of economy of effort and skill performance will be available with high accuracy and in the required form. The research aims To: Comparing some of the values of the biomechanical variables for the frontal smash in volleyball according to the programs (VDCD – Cuter) and (AutoCAD) with the international model for female players of Al Amana Sports Club.

   Identifying the differences in the values of biomechanical variables, the researcher concluded the following:

The global model achieved significant differences in all biomechanical variables under investigation

The research sample of Al-Amana Sports Club players achieved good results in biomechanical variables, but did not come close to the global model.
