دراسة مقارنه في بعض المتغيرات الكينماتيكية لمتسابقي منتخب مصر و المستويات العالمية في مسابقة إطاحة المطرقة

Abstract EN

The main objective of this study is to study some of the variables of the skill performance of the Egyptian team racers in toppling the hammer and compare them with the high levels to provide coaches with them to work on improving the digital levels achieved the research sample was selected in a deliberate way and represented in the number (3) male contestants the strength of the Egyptian team for the first degree, and those seeking to qualify for the Olympic games has been using the descriptive survey approach based on kinetic analysis, using two-dimensional video photography the results indicate to confirm that the gradient in the decrease in rotation times from the first rotation to the third only, and that the fourth rotation time is higher than the third, while the members of the research sample had the fastest rotation (the second), while at high levels the fastest rotation was (the third), and the largest increase in the speed of rotations for the members of the research sample was during the first rotation followed by the third rotation, while at high levels the largest increase in the speed of rotations was during the fourth rotation followed by the first rotation, the speed of the hammer for the members of the research sample was less than 4 m / s from the high levels.
