AN ANALYTICAL STUDY INDICATOR OF SOME BIOMECHANICAL VARIABLES FOR SKILL OF SNATCH LIFT FOR SOME OF SPECIALIZED SCHOOL WEIGHTLIFTERS

Abstract

Performance of movement of gravity and quickly, which depends on the preparatory period for performance of skill, requires greater great power result, in addition to fact that performance requirements require player to put greatest strength during skill performance to have to occur in movement, which affects outcome of the power used Therefore, he needs a large force on the ground that results in the land’s reaction to the player. Some players of specialized school for research and experimentation using skill of kidnapping to study in order for image to be more clear to the coaches, which provides information that enables these trainers to explain performance more accurate For this skill, which raises level of our players in this center in terms of skill, so researcher considered an analytical study of the index of some biological variables of the skill of kidnapping for some players of specialized schools in weights, research sample included some specialized school players to lift weight of sports season 2022-2023 m, which numbered (6) Two players for each of them, because they are of good level, and their percentage is (37.5%) of the original community. filming was performed by Sony video camera with a frequency of 100 images /s placed on a triple holder at a distance (5 m) and a height (1.40 m) vertically on the field of movement and these distances show the full lift, and some biometric variables of the research sample represented by following variables (reaction strength index, kinetic energy, work, ability), analysis by (Kinovea) program was studied eighteenth edition .SPSS VER 21 statistical bag was also used to obtain the search results, after which results obtained and discussed by researchers, as for most important conclusions that reach researchers are: 1 - Biomechanical variables have an important effect on outcome of artistic performance of Snatch Lift because of their effective role. 2 - Speed has basic and large role on biomechanical variables studied in research, and therefore we note that results are within required level because player moves at a somewhat small distance
