A Comparative Study Of Some Of The Kinematic Variables Between The Right And Left Player And Their Relationship To The Accuracy And Speed Of The Performance Of The Crushing Skill Of The 2nd Center Volleyball

The workers in the field of sports were interested in studying moving skills and analyzing and developing them as well as enhancing the details of strength in performance, the goal is not only to know the areas of weakness but also to reinforce the areas of strength in order to develop the components and variables of performance, for this was interested in studying some of the kinematic variables between the player who uses the left hand and the player who uses the right hand which affect the performance of the crushing hit skill from center 2 and its relationship to accuracy and speed of performance through which we seek to achieve results to find the characteristics of our ability to Relying on them in training then improving the level of technical performance of players, the study aimed at identifying the differences in the values of some kinematic variables between the player who uses the left hand and the player who uses the right hand and to recognize the relationship between en the values of some kinematic variables, accuracy and speed during the performance of the skill of crushing beating of center 2.The researcher used the descriptive approach, while the sample of the research were the players who perform the skill of crushing beating of center 2 they were (4) players of the Iraqi national volleyball team of the season for the period from 2014 to 2019, and was The sample was filmed with two Chinese-made Video imaging machines (Casio) (240 ph / sec) and an American (sports radar) to measure speed, and was analyzed by the (kinovea) application, and the data were processed statistically using the program (SPSS ver. 23). After discussing the results, the most important conclusions were the preference in the values of the kinematic variables under consideration for the overwhelming beating of the left player and the right player, and there is a correlation in the level of accuracy and speed with the kinematics variables of the overwhelming diagonal and straight beating of the left player for the right player.
