العلاقة الارتباطية بين المتغيرات الكينماتيكية و زاوية التحرر للهبوط بمهارة القلبتين الهوائية الخلفية المكورة من جهاز العقلة في الجمباز

الملخص EN

The purpose of this study is to investigate the relationship between kinematic variables and the angle of release from the high bar, where gymnasts need an appropriate angle of release so that they can complete the rotation successfully and landing correctly.

The study selected 11 gymnasts who participated in the 2018 Iraq Clubs Championship held in Baghdad and analyzed their best performance in the competition.

The camera used for this study was HDR (for Sony HDR-200) and then converted and analyzed by (Kinovea 25.5).

After extracting the data we analyzed, we performed statistical processing using the correlation coefficient and linear regression using the SPSS ver 19.

The the difference from each factor the level is set at p <.05.

and the study concluded can be estimate of the angular velocity and flight time can be the best factor for the angle of emulation through (0.474 for angular velocity and 0.49 for flight time ) and significantly affected the angle of release p <.05(T = -2.85 for angular velocity and -2.92 for flight time).

Therefore, we can expect the center of mass to rise score performance through angle of release, to complete the rotation successfully and to drop the player correctly of raise his score performance in the horizontal bar, In addition to the removal of danger during his landing.We have derived the dependent variables of the angular velocity and flight the estimated equations of the regression line representing the relationship between the angle of release and the: Angle of release = 102.09- 4.85 x angular velocity.

Angle of release = 177.3- 74.2x Flight time.
