التحليل الكينماتيكي للإرسال في كرة الطاولة من ارتفاعات مختلفة لدى لاعبي المنتخب الأردني

الملخص EN

This study aimed at identifying the values of some kinematic variables that affecting of the serve technique, as well as to identify the relationship of the high ball off the table at the moment of contact with bat and kinematic variables under study.

to achieve this, the researchers used the descriptive approach his style the survey, on (6) table tennis players from the Jordanian national team.

the study sample was filmed by using tow video camera (Sony HDR-CX220E) reached speed (50) frame / s.

the study examined: height ball off the table at the moment of contact with the bat, and the time of arrival of the ball to competitor, the velocity of bat, ball, and the joints of the shoulder and elbow and wrist.

the study results showed : the study sample technique in this skill is characterized by some weaknesses, also the average of the velocity bat was(2.62± 0.20)m / s.

as well as the average of the velocity ball (4.34± 0.59)m / s.

furthermore, the study results showed significant statistically correlation between high ball off the table at the moment of contact with bat, and the velocity of bat, ball, and the joints of the shoulder and elbow and wrist.

the researchers recommend: the necessity informed coaches and players of the national team on the results of this study, and focus on the skill of the serve technique in coaching.
