أثر تمرينات خاصة في تعديل و تحسين بعض المتغيرات الكينماتيكية المرتبطة بأداء مهارة الإرسال الساحق بالكرة الطائرة

الملخص EN

The aim of the research is to identify the variables kinematic and their values to the transmission performance skill for research sample., As well as, place a special exercises to improve some of variables kinematic that are associated transmission performance skill in volleyball.

Also, to identify the effect of exercise in modifying and improving some variables kinematic that are associated with transmission performance skill in Volleyball.

the researcher is used the experimental approach because is suitability to the nature of the research.

The researcher conducted the experiment on a sample of (12) player represented denominator Al-Kasem club players.

The researcher is used a group of exercises for the purpose of improving the range of skill variables biomechanics in transmission overwhelming in volleyball and within a period of six weeks and two units per week and then the researcher did second test after training and the researcher has found that there is an improvement in the level of technical performance and especial with the variables under study.

The researcher concluded that there is a clear real effect and exercises to modify and improve some of the variables, including (approaching speed, angle of the ball, the angle of advancement, the peripheral speed of the striking arm, starting speed of the ball)., As well as Did not show a significant differences between the results of the pre and post tests in the two variables (maximum height, horizontal distance to enter the stadium) The researcher is recommended to do a similar researches but in different age groups.

As also, the research is recommended to focus on improving the level of technical performance of skill transmission overwhelming in volleyball that are associated the variables kinematic for Iraqis players.
