A study of some biomechanical variables of the jumping skill in the kinetic rotation Kankashu-kata as a basis for developing specific exercises for kata players

Through the researcher conducting reconnaissance studies on Karate players and conducting many personal interviews with some coaches and specialized professors, and through video filming, I noticed the following: that there must be an appropriate amount of strength, speed, balance, and grace in the kinetic movement. And as far as the researcher knows, there is a dearth of research that dealt with the analysis of the performance of the leaps in karate and that jumping in the whirling movement of Kankashu-kata has not been subjected to any detailed study despite its importance to all kata players without exception, and this prompted the researcher to study the research problem that is represented In identifying the most important mechanical variables for the skill under study, then designing a proposed specific training according to the mechanical variables of the skill under study.

Research objective: -
- Determination of some biomechanical variables of the jumping skill with the kinematic cycle of Kankashu-kata.

Search questions:
- What are the most important biomechanical variables of the jumping skill in whirling motion, Kankasho-kata kinematic movement?
What are the specific qualitative exercises in the light of some biomechanical variables for the skill of jumping in kinetic rotation Kankashu-kata.

Research hypotheses :-
- There is a statistically significant correlation between some biomechanical variables and the level of performance of the jumping skill by rotating the kinchacho-kata kinetic.
