خصائص منحنى الكينتك الخطي لأبعاد الحركة و أثرها في إنجاز الواجب الحركي لمهارة الضرب الساحق من مركز (2)‎ للكرة الطائرة من الجلوس

الملخص EN

The study focused on the importance of spiking skill from position (2) in the game of volleyball from sitting because it has a role in deciding the results of matches and dealt with the importance of using modern laboratory devices (BUSAN system) in detecting the values of linear kinetics variables and their effective impact on Training and making use of it in developing skills, It also aimed to try to identify the characteristics of linear kinetics for dimensional movement and the kinetic duty of the players who hit the center (2) in the game of volleyball from sitting.

Because using these numerical values in the training process has many benefits and functions, One of the most important of them is identifying the correct kinematic pathways for accuracy of the blow and other important benefits that work to achieve the greatest possible training and educational competence.

In addition to saving the effort and time spent in the training unit, the researcher used the descriptive approach and identified the research community, which is the national volleyball team from sitting, and deliberately chose the players who perform the crushing beating from Center (2) and their number (10) As for the most important conclusions, the results showed the importance of providing information about the chain of forces during the performance in the main stage and then making use of it in explaining the movement.

The results of the characteristics of the (linear) kinetic curve of the variables of the power chain showed a consistent shape in the main stage (crushing) with the volleyball from sitting for parts The body and each according to the amount of its mass and its contribution to the multiplication stage.
