Abstract EN

The aim of the research is to find out some of the kinetic variables of the bat and ball using the SMART SENSOR and its relation to the precision of the Slice Serve.

The research sample consists of (4) players who are registered in the records of the Central Tennis Federation in the region.

The intelligent sensor and test conditions were set for accuracy.

The study finds that there are significant differences (0.05) for the variables (weighted velocity of the bat, the speed of the ball and the number of ball rotation) in accuracy during the performance of the Slice Serve of the advanced players in the Kurdistan Region of Iraq in order to have precise numerical results that serve the player and trainer to get positive results that help the development of this game.
