Contribution ratios of the kinematic indicators for the skill of categorical service with the face of the club The background and its relationship to the accurate fall of the ball for table tennis players in the State of Kuwait

This research aims to identify the most important kinematic indicators of the skill of categorical transmission to the face of the paddle and its relationship to the accuracy of the fall of the ball for table tennis players, the researcher's use of the descriptive method based on the method of high-speed video analysis of the skill using Simi Motion kinematic analysis program, and the research sample included 5 players classified from The best ten players in the State of Kuwait under 19 years old.
The researcher used the SPSS statistical program to perform multiple regression analysis to accurately predict the fall of the ball during the performance of the categorical serving skill against the back club, where 10 statistically successful attempts were addressed to reach predictive equations through which it is possible to accurately predict the fall of the ball in terms of the kinematic indicators of the weighted moment, collision and contribute to Increase the accuracy of the fall of the ball during the serve cutter with the face of the back club
The most important findings of the researcher is the presence of 9 kinematic indicators that contribute to increasing the accuracy of the ball fall during the performance of the transmission during the weighted moment, in addition to the number of 9 kinematic indicators that contribute to increasing the accuracy of the fall of the ball during the performance of the service during the moment of collision,
