A Comparative Research Of EMG Feature On Shot Put Final Push Action And Specialized Training

Research purpose:This thesis is the use of surface electromyography technology Final Push technology movement and electromyographic characteristics of specialized practice comparative analysis of the body muscles experiments demonstrated for the entire monitoring biological signals. Further understanding of the action do Final Push technology demonstrated by the EMG features specialized training and when demonstrated by the EMG characteristics, and then compare the study results Final Push action with specialized training in the operation of the technical and correlation fit, can provide a reference for effective training in the future.Methods:Students do complete glide shot put action with five specialized technical training, the use of portable ME6000 in action during the EMG to five students in field tests, EMG site collection, and then use the software since Megawin analysis system with the EMG interception and finishing, and finally converted into concrete data obtained EMG features generated for each student to do each action.Results:1. Final Push technology in action five dedicated reps electromyographic characteristics in comparison, it is clear that in situ lateral direction Shot Put throwing exercises EMG features in Final Push largely have a high degree of technical movements relevance and fit of this exercise for final Push technology movement has a good supporting role, is more conducive to understand and master the technical movements, the theory resides in practice.2. Shot in situ push up, push the shot put in place for the throwing direction, in situ and in situ lateral twist Shot Put Shot Put back practicing with the glide shot put final stage of the technical characteristics of the force is not very good correlation. RMS amplitude in terms of the average value of each muscle during exercise demonstrated the contribution rate, have shown differences.3. Rectus shares in favor of the development of in situ and in situ push up shot for shot put throwing direction reps, biceps femoris, biceps, rectus femoris, radial tibialis anterior muscle and the development is conducive place Shot Put lateral swivel motion exercises, it is conducive to the development of the latissimus dorsi Shot Put back in place of reps. Pectoralis major muscle groups in the upper limb force development for throwing the shot put immeasurable role.Conclusion:1. Shot Put in place a lateral direction to practice throwing and glide shot put final exertion technical movements have great relevance and fit in theory and practice, can be used as an effective aid for training, the development of technology finally forced action.2. For muscle development exercises beneficial method to interspersed, and implementing training methods. So as to ensure the full development and development-related muscle coordination, help lay a good foundation for mastering motion technology to improve the level of training, can be all together all aspects of training,play the greatest overall efficiency of training.3. Since the measuring instruments obsolete, wire interfaces easy to fall off, to some extent limit the normal force pectoralis major, in future experiments, we need to solve this problem, make technical movements more stretch, smooth and powerful.
