Some kinematic variables to find the best position to stand ready for young lifters and its relationship to the accuracy of the snatch

The sport of weightlifting is currently witnessing a great development in achievements as a result of the development of physical and functional capabilities through Opening up the field of weightlifting to scientific researchers with their various scientific specializations, as it actively contributed to the development of achievement and the upgrading of the capabilities and physical, motor and mental qualities of quadruples and directing these capabilities towards the best in performance and the high level of achievement and the investment of effort and time during training. The importance of the research comes from the bio-kinematic variables related to the stand-by and thus reaching the correct ideal model by achieving the bio-kinematic requirements. The research problem here is what the standby mode contributes to achieving the main factors in lifting weights and comes through the relationship with the kinematic variables and thus reaching the correct ideal model for the standby mode by achieving the biokinetic requirements that give us quantitative estimates in the values of the variables to avoid the weakness that occurs in the standby mode. Through the researcher's follow-up of developments in this game and watching many local tournaments, the researcher found that there is a weakness in the standby mode. There is a relationship between some kinematic variables and the readiness pause, and to identify the contribution ratios of kinematic variables and the readiness pause. As for the hypotheses of the research, identifying the values of some bio-kinematic variables and their relationship to the standby pause, there is a significant correlation between some bio-kinematic variables and the standby pause. As for the field research procedures, the researcher used the descriptive approach as it is the most appropriate way to solve the research problem, and the sample included (2 lifters) from Al-Amara Club (3 lifters) from Al-Kut Club with a weight of (69) kg. As for the conclusions, there are significant contribution rates for some kinematic variables, including the angle variable. The knee where the biggest contributor in the grabbing phase. As for the recommendations, the trainers must familiarize themselves with the foundations and rules of biomechanics and kinetic analysis in addition to other sciences so that they can have the correct training according to the scientific foundations and the correct information.
