An Analysis Of Sports Biomechanics On Jerk Techniques Used By The Elite Female Weightlifters Of Seventy-five KG

Uses the Ariel APAS System3D analysis system analysis, to our country75Kg elite women weightlifters jerk techniques kinematics is analyzed, and the technology rationality to make a diagnosis and evaluation. On three-dimensional video analysis research, domestic and foreign literature focused on the peak period of athletes, and the research on Athletes’ technical advantages are discussed. On the athlete ’s technical problems and inadequate research is less, the content analysis focused on the study of the overall technical characteristics of athletes or a specific technology characteristics of athletes at home and abroad, but few for a given level of athlete ’s technical reports, this experiment on the aspects of research, exploration75Kg level of excellent female athletes in clean and jerk characteristics results show that:the object of study is movement in the sagittal axis of center of gravity of the barbell and body centre of gravity is reasonable distance, in the frontal axis of center of gravity of the barbell and body barycenter offset smaller; the joint force order consistent with movement of biomechanics; jerk force when the barbell velocity reached1.6m/s above, a man; object of study Jia Wenqing had" throw" phenomenon; research object Cao Lei potential is great. By75kilograms of elite female weight lifting athletes participate in the Olympic Games a year ago very technical parameter analysis, find the advantages and disadvantages, so for a year will attend the London Olympic Games for young women’s75kg class weightlifting athletes theoretical guidance, improve the organism movement ability.Suggestions:Chinese women’s75kg class weightlifter squatting with between the level of elbow position between the elbow position, upper arm and trunk angle of75-85; trunk in jerk force to remain upright; training in upper limb movement synchronization and upper limb strength balance. Cao Lei should be reasonable under the guidance of attempt greater weight barbell. Cao Lei should be reasonable under the guidance of attempt greater weight barbell.
