علاقة السرعة الزاوية لمفصلي الركبة و الورك في مرحلة السحب الأولى بقيم انحرافات الثقل في رفعة الخطف

Abstract EN

The skill of snatch as a skill requires high physics abilities and dynamic susceptibilities to practice and to activate the high achievement in that skill that depends on the application of technical aspects in a more integrated manner as well as to perform the application of the biomechanical aspects.

The deviations of weight from the imaginary line of the body for the weightlifter in the stages of the snatch skill is one of the most important biomechanical elements that set the shape of the dynamic trajectory of the performance.

The aim of the study was to identify for the value of the velocity of the hip and knee joints in the first drag step and the weight deviation in the snatch lifting.

The researcher used the descriptive method (the study of associative relationships), as the most appropriate to achieve the goal of the study, and the research community consisted from six weightlifters of the Iraqi national team (Advanced category) in weightlifting, And the results were as follows : There was a significant positive correlation between the velocity of the knee and hip joints in the first drag step \ stage and the deviation of the first weight (D1) in the snatch.

And Also the research recommendations include : It’s not necessary to have the digital values obtained by the researcher are an example for each weightlifter, as the biomechanical properties differ from a weightlifter to another.

but they can be useful for comparison in training and research.
