الملخص EN

The importance of the current study lies in the ability of the table tennis player to estimate the place of the fall of the ball on the table, which is one of the good qualities that can increase the superiority during the games, and this requires a high concentration and the use of many training methods, whether soon or far from the table That the type of strike used and the angle of the playing arm will decide where to fall the ball.

The problem of the search is about the type of strike used and the angle of the play arm as well as after the proximity of the player from the table during the game is one of the factors that affect the player's ability to direct the ball to a specific place on the opponent's table, and many players emphasize the speed and strength of the ball without confirming the place of fall, which causes the dispersion of strikes and exit many of them Off the table thus lose many points The study aimed to identify the location of the fall of the ball according to the distance of the player from the table as well as the corner of the facility, in addition to the relationship between the amount of the corner of the facility and the distance after the player from the table in both the front and rear spiral and estimate the location of the fall of the ball; 8) 17 – year-olds representing IFK table tennis and registered with the Swedish Federation of Table Tennis.

The researchers concluded in their conclusions that the proximity of playing from the table can positively affect the estimate of the place of the fall of the ball, and that playing at a relatively large angle is not in favor of variable estimate the place of the fall of the ball despite the fact that the factor of the increase in the speed of the ball, Playing away from the table, as the variant of the dimension of the table is proportional to the estimate of the location of the fall of the ball, as for the variable angle of the facility is inversely proportional with the estimate of the location of the fall of the ball.
