A comparative study in the point of view of the weight bar between the Iraqi team and the Iranian team

دراسة مقارنة في انحرافات قضيب الثقل بين المنتخب العراقي والمنتخب الايراني في رفعة الخطف

Abstract

The aim of the research is to identify the differences in the deviations of the weight rod (center) between the Iraqi team and the Iranian team in the snatching lift. every team.
The researchers used measurement, testing, technical scientific observation and analysis of the content of previous studies. To achieve the technical scientific observation, the researchers used two Copro Hero plus3 B digital cameras. The two cameras were placed at a distance of 3.5 m from the right and left sides, and the lens height of the two cameras was ( 1) m, and their speed was (50) frames per second.
The following analysis programs were used (Kinova, ACD see 10, Adobe photo shop 8, Excel) and the researchers processed the data statistically using the Spss statistical package (arithmetic mean, standard deviation, percentage, and t-test for independent samples), the following conclusions were reached. :
1- The Iranian team outperformed the Iraqi team in the deviations of the kinetic path of the weight in the snatch, with the exception of (D3), the Iraqi team was the best.
2- The technical performance of the Iranian team was closer to the ideal compared to the technical performance of the Iraqi team, and this was clear from the data and results of the research, as the movement path of the weight of the Iranian team was characterized by less deviation of the weight from the imaginary gravity line from the Iraqi team.
3- The Iranian team outperformed the Iraqi team in most of the studied weight deviations by (83.33%), while the Iraqi team outperformed by (16.67%).
