Abstract

The research aimed to know The Kinematic Variables of Elite Egyptian Hammer Throwers Performance researcher used a descriptive approach based on kinetic analysis and the use of three-dimensional imaging, The research sample was selected deliberately and was represented by three male contestants under the age of (20) registered with the Egyptian Athletics Federation.Conclusions of the resarch was ensuring the gradient in the decrease of rotation is from the first rotation to the third only and that the time of the fourth rotation is higher than the third,the double anchoring time of the first and second player was better than the third player, while the third rotation was less, and the search sample numbers in the double anchoring were close due to the importance of the double pivot stage during rotation in that it is the part where contact with the ground is made and the body gains speed during the single pivot of the second stage, the more the pivot is more positive, the more the rotation speed increases in general,the excessive decrease in the double pivot time of the third player during the turns from the first and second player indicates his inability to control the rest of the turns due to the reduced ability to control the individual pivot,the use of kinematic analysis in the hammer knock-out competition helps to identify weaknesses and strengths in skill performance, which helps players improve their level and achieve the highest digital level.
