The Different Movement Form Parallel Bars Arm Expends And Contracts The Movement Myo-electricity Characteristic Analysis

Skill training in gymnastics, the parallel bars parallel bars strength of arm flexion and extension movement is the most simple movements, upper limb strength training is also an important means. How in the shortest possible time and the shoulder straps to enhance the strength of upper limb, the main focus on training difficult moves to master a more solid basis for the purpose of action in order to shorten the cycle of training elite athletes, as a gymnastics researchers an issue. The primary solution to this problem is clearly the best pieces of muscle training methods, which is precisely the ultimate goal of this study.The purpose of this study points to the use of EMG and high-speed photography, in different forms of movement-----arm flexion and extension and arm flexion and extension support for the former state, by adjusting the width between the parallel bars, wide grip on the state of different completed the same analysis of arm flexion and extension movements a comparative study of the basic conclusions drawn are as follows:(1) parallel action arm flexion and extension under a state of wide-grip exercise training of the latissimus dorsi best;(2) flexion and extension arm moves parallel bars relief under the standard practice of the triceps and pectoralis major of the best training;(3) parallel arm flexion and extension movements narrow grip on the state of practice before the beam deltoid, trapezius, extensor carpi radialis best training;(4) before the parallel bars to support wide-grip arm flexion and extension in the state of practice in the beam of the deltoid muscle and the exercise brachioradial best;(5) before the parallel bars to support the standard arm flexion and extension movements narrow bar width and grip exercises of the muscles under the effect of the exercise is not very obvious.
