دراسة مقارنة لبعض المتغيرات الكينماتيكية بين محاولات النجاح و الفشل لمهارة القلبة الهوائية الخلفية المكورة من الثبات لدى لاعبي باركور البصرة

الملخص EN

Three-dimensional technology.

We can see the athlete’s movements from any angle, for example these angles (back and front of the player as well as the corners of the top or the bottom) and we can measure the real angles of any part of the body as these angles express accuracy in the measurement and represent their true values and we can measure Also accurately accelerate linear, angular and on axes (x,y,z).

The aim of this study is to compare the main kinematics factors between success and failure attempts in back somersault standing performance of Basra Parkour players.

Four players participated in this study.

three cameras were used in this study at a rate of 240 images per second.

The success movement and failure movement were selected for each player for a three-dimensional analysis, and through the results, it appeared that the path of the attempt to succeed was longer than the attempt at failure in time.

The velocity of the hand segment and the maximum velocity in the attempt to succeed were greater than those of the attempt to fail, and this result was an increase in the velocity of the projectile and an increase in the vertical height of the center of mass.

When standing up in Event 2, the amount of flexion of the hip and knee joint angle contributed to the optimal state of advancement and at the peak point the hip and knee joint angle was bent to the maximum to reduce the moment of inertia.

At this point, too, the higher parties in the attempt to succeed extended more than those in the attempt at failure.
