المتغيرات البيوكينماتيكية لمهارة اليورشينكو مع اللف حول المحور الطولي لجهاز طاولة القفز كأساس لوضع الأحجام التدريبية

الملخص EN

The study aims to answer some of the questions of women's artistic gymnastics coaches, which were causing them to refrain from preparing and training their gymnasts on Yurchenko skill with a turn around the longitudinal axis (360°, 720°) that has a D-score (4.6, 5.4).

These answers will also help them to improve and develop this skill to higher difficulties as provided in the General Judges Rules 2017 / 2020 for vault jumps.

The study conducted on (3) players from the first national team of women artistic gymnastics by purposive sampling, using the unit-set experimental method using the pre and post measurements on one experimental group as it was suitable for the nature of the study where the basic experiment was applied for (12) consecutive weeks.

The content of the training program was implemented in the halls complex (1) in the Olympic Center for National Team Training where the study sample, approved apparatuses, and additional equipment to identify the kinematic variants of the Yurchenko skill with a turn around the longitudinal axis (360°, 720°) were available.

The study used the anaerobic energy production system as the basis for developing training sizes to improve and develop the second flight of the Yurchenko skill with the turn around the longitudinal axis (360°, 720°).

It turns out that the skill is not associated with a particular tempo for its performance; each player has her own rhythm, usually called style.

The less speed it exits the push surfaces, the more she loses the speed.

Exit speed must be faster than entrance on the push surfaces whether it was land, a ladder, or a vault table so that we could do the kinetic outcomes properly.
