نسب مساهمة بعض المتغيرات الميكانيكية لحظة ضرب الكرة في مستوى الأداء المهاري للضربة الخلفية بكلتا اليدين للاعبي التنس

Abstract EN

The research aimed to identify the contribution rates of some mechanical variables at the moment of hitting the ball in the skill level of the backhand shot with both hands among tennis players.

The researchers hypothesized the existence of contribution rates for some mechanical variables in the level of skill performance of the backhand shot with both hands among tennis players.

The research sample consisted of (8) tennis advanced Players from ten in Nineveh Governorate.

The researchers concluded that there were significant contribution rates for the two variables (right knee angle, height of the center of gravity) at the moment of hitting the ball in the skill level of the backhand shot with both hands.

The researchers recommended tennis coaches emphasize on adopting mechanical variables that showed moral contribution for its role in developing the skill of backhand shot with both hands, with more attention to mechanical variables that were produced by the study.
