application/pdf It has become clear that the player does not have enough information about the characteristics of the skill performance of table tennis to make training easy, which is exemplified in the practice of the skill. Technical information about any skill means having a good understanding of its performance in the light of information that helps in identifying the required movement procedures to make possible the highest professional performance quality, skill execution and the greatest variety of application methods.<br />Speed, spin, and direction are the essential factors in determining the results in table tennis competitions. The spin hit is one of the most important strokes in table tennis, as it causes a low flying arc and gives the ball great quickness and rapid turnaround.<br />Therefore, a problem in the biomechanical analysis of the backhand topspin was to identify the kinematic characteristics of this skill and determine the effects of the biomechanical variables on the performance accuracy of expert and novice players.<br />The sample consisted of 11 expert table tennis players (5 males and 6 females), and 4 novice table tennis players (2 males and 2 females). The variables were 40 backhand strokes with topspin for each player (i.e., the performance technique and maximum velocity trials).<br />The novice players displayed lower performance accuracy than the expert players in maximum velocity performance and in the technique trials (mean= 1.44, 1.51, respectively). In addition, the effects of the percentage of the biomechanical variables on performance accuracy were different between the maximum velocity and technique trials for expert and novice players. The results showed that the velocity of the novice players had a considerably lower effect on performance accuracy than that of the expert players in the technique and maximum velocity trials (the contribution of the velocity= 16.1%, 22.1%; 23%, 52.5%, respectively).<br />Moreover, the maximum velocity trials of the acceleration biomechanical variable showed a considerably higher effect on performance accuracy in the novice players than that of the expert players (30.1%, 15.3%, respectively).<br />Furthermore, the technique trials of the angle biomechanical variable showed a considerably higher effect on performance accuracy than that of the angle in the maximum velocity trials of the expert players (42%, 29.5%, respectively). However, in the novice players the technique trials in the angle biomechanical variable showed a considerably lower effect on performance accuracy (20.5%) than that of the angle in the maximum velocity trials (28.9%).<br />In addition, the results showed that the angular velocity of the novice players had a considerably lower effect on performance accuracy than that of the expert players in the technique and maximum velocity trials (the contribution of the angular velocity= 11.8%, 17.9%; 2.1%, 30.8%, respectively).<br />Moreover, the momentum of the expert players had a considerably higher effect on performance accuracy than that of the novice players in the technique and maximum velocity trials (the contribution of the momentum= 23.1%, 52.5%; 21.6%, 22.1%, respectively).<br />Finally, the technique trials of the rotation biomechanical variable showed a considerably lower effect on performance accuracy than that of the maximum velocity trials of the expert players (the contribution of the rotation= 2.5%, 17.6%, respectively). 2010 Der mechanische Beitrag der Armbewegung während der Ausführung des Rückhand-Topspin durch Tischtennisspieler 2011-03-24T15:38:39Z Ebrahim, Habib Ebrahim, Habib The Mechanical Contribution of the Arm Movement During the Performance of the Back Hand Topspin Table Tennis Players 2011-03-24T15:38:39Z eng deposit-license
