The Elite Male Weightlifting Athletes Shanxi Province Movement Technology Electrical Test Research On The Cleanand Jerk

Objective:Through the elite male weightlifting athletes clean jerk movement technology in ShanxiProvince sports biomechanics test, revealing the clean and jerk technology at different stagesin major muscle group technology with the action, the relationship between weightliftingathletes for the future technical diagnosis and provide certain scientific basis for the specialstrength training.Methods:using high-speed cameras and methods of electric telemetry equipment clean and jerk formen’s weightlifting athletes tested synchronous movement technology, the strength of twokinds of load under the corresponding average amplitude of each muscle electromyography.To the left and right side of the same muscles in action at the same stage. On the same jointpoint of agonist and antagonist coordination is analyzed.Results:under different load intensity of each muscle group different actions in the clean and jerkstage show the emg average amplitude better regularity, each muscle group showed theelectrical test results compared with the role of technology in the clean and jerk each musclegroup.Body overlap with the left and the right of the muscle trace, comparison the symmetrycharacteristic of two muscles. First can see on both sides of the intuitive muscle dischargemode during the whole process of consistency in the movement, the second is to show the muscles start to activate and stop activated relative should point in time, can accurately judgethe athletes with start and end.Chart also provides the muscles on both sides of integralmyoelectricity, amplitude, peak amplitude, the average contribution rate, and muscle. Tofacilitate visual analysis. Test report is designed for measuring muscle coordination activitiesaround a common area or one side of the body (unilateral action). Single page report of eachmuscle emg model respectively.Conclusion:Through the electrical testing, analysis, reveals the subjects measured muscle in the cleanand jerk technology the role played by the different actions of stage. Power is embodied in thepre squatting on a rising and two inertial phase within the lower limb muscle group, muscle,shares and biceps plays a main role, and in supporting the bell stood up sacral spine muscleflexor muscle of wrist, feet side and triceps plays a main role. Sacral spine muscle andgastrocnemius whole action phase power level fluctuation is small, the average amplitudevalue in smaller scope change, that the two muscles supporting the main supporting role.Every muscle in the action phase of the hair is constantly changing and adjusting forcecharacteristics, tip in daily training should be in the muscular strength, muscular endurance,muscle power, biggest three aspects flexible selection, not just focus on the one hand, in thepractice.
