تقويم مسار الثقل في رفعة الخطف لرباعات المنتخب العراقي

Abstract EN

The aim of the research is to assess barbell trajectory in snatch for Iraqi female weightlifters.

The researcher specified the kinematical variables of the weight's path in snatch and they include (heights H1, H2, H3 and Drop X) Deviations (D1, D2, D3).

The researcher used the descriptive method.

The subjects were (6) female weightlifters compared to (6) first ranking world weightlifters 2015.

Two cameras type )Casio EX-ZS100(, placed in(3-D) position were sued along with dartfish app for analysis the performance.

The researcher used (SPSS) for statistical analyzes, which included: mean, Standard deviation, minimum, maximum, percentage, Shapiro–Wilk test, t-test for two independent samples.

There researcher concluded that the Iraqi model barbell trajectory didn't differ from world model except in the maximum height.

Accordingly, the main recommendations were as follows: Emphasis on not to exaggerate in the height of the barbell, and taking the barbell to the typical height in every phase.

Pull the body lightest weight under the bar instead of lifting the barbell after arriving the critical height to do the turnover under the barbell Development the Motor Abilities which inked to a large extent with the speed of turnover under the barbell.

Conduct similar studies in clean& jerk lift.
