Attribution And Countermeasures Very Action Failed On The2012London Olympic Weightlifting Sport

Looking abroad this is not very common on the technical research and the experience of staying in the general experience, current research is to direct and indirect reasons which led to the very reason for the failure, there is a large training guidelines and conclusions suggestions but the actual tournament does not maintain statistics on the most common action on quite failed, and no statistics on the causes of the very very most common cause failure actions.In this paper, literature data method, video analysis, mathematical statistics, expert access method, comprehensive analysis, through the latest technology rules the world weightlifting, weightlifting quite technical research for the London2012Olympic weightlifting sport athletes performed in group A Jerk Competition cite statistics, lists very action failed due to the London Olympics, finishing them separately and summarized and analyzed, and compiled a method to improve the training of technical movements. The results of this study are as follows1) The2012London Olympic weightlifting program, A group weightlifting athletes, the total number of games for155people,80men who sport; women athletes75people.2) for the2012London Olympic weightlifting competition, a total jerk action action failed13failed action (dead lift, the second push, to send forward, send backward, not propped hands, legs out, went into the shoulder, the center of gravity to the former, the focus back, knees down, pre-squatting failure, hands and feet are not in place, not to step on the back foot stability)3) A group of men94KG class snatch the highest success rate, while the success rate of the lowest grade69KG; Women Group A match snatch highest success rate75KG,53KG and58KG lowest success rate of these two orders of magnitude4) Men jerk cite failures102times; cite higher than92times the number of successes, men’s56KG and62KG grade level higher than the success rate of failure. Quite the failure rate on62KG105KG grade level and more than90%; quite on the level85KG failure rate of76.92%; cite the success of the women’s clean and jerk was129times; higher than the failure to cite the number86, the failure rate is very action reached68.6%. Although the women in the statistics show a low failure rate, but the failure rate is quite a magnitude7have six orders of magnitude in the very action failure rate in more than60%, which has reached the women’s48KG class90%.5) Men jerk action failed, went into action fails shoulder movement as a percentage of the total failure of29.2%; Women jerk action failed, went into action to total failure of the action failed shoulder percentage was23.0%.The above summary of the findings, the study aims to modern technology trends weightlifting have a more comprehensive understanding of the causes weightlifting coaches attention quite technical training, weight training can be in the future in the correct grasp of the very technical improvement and improved to provide a theoretical basis.
