Study On The EMG Characteristic Analysis Of The Upper Limb Muscles And Pectoral Muscle In Push-ups

Strength training is the necessary means to increase muscle strength, and power quality isdecided to performance of important physical elements of, so, the scientific training method hasbecome a muscle strength training core factors, but at present, the commonly used for strengthtraining method research mainly confined to training plan, training methods, training load analysisand discussion, in view of the specific strength training action muscle contraction characteristicsresearch is still rare. In addition, at present in the domestic sports anatomy of the materials on themuscular movement effect is also mainly comes from taking skeleton or the body prediction, singlepiece of muscle electrical stimulation, a certain piece of muscle paralysis after the loss of functionand the children living on the methods of contact the speculation of the results, and narrative isvery general. Therefore, this paper will from sports anatomy discipline construction and strengthtraining the practical needs, based on the motor function morphology basic principle, USES theaction structure analysis and table facial electric diagram test methods, to analyze and study flat lieby structure characteristics and muscle function and characteristics of synergy, analyzes differentpalm subtalar muscle activity status and the changes of coordination characteristics, in order toenrich and develop the basic theory of sports anatomy, for sports practice provide the necessarymethods and means.This study on strong and handsome group and ordinary group of20people,were studied respectively4kind of palm distance push-ups action master.To work muscle watchfacial electrical test, and the push-up action structure, myoelectricity time domain and frequencydomain indexes Analysis.The experimental research results with palm distance widened, push-upsaction to deltoid toe-in, pecs and biceps brachii stimulation to strengthen, to tricep stimulationabate. The palm distance to change the influence of pectoralis major muscle contraction maximum,to tricep and biceps brachii influence take second place, the deltoid toe-in shrinkage influenceminimum.(2) push-ups training level in the most complete push-ups when the movementprominent performance: the pectoralis major contribution of the larger, and with the palm distanceincrease of pectoralis major mobilization increased significantly; Another significant feature isforearm flexor and the forearm extensor the synergy of shrinkage ability also is better than theordinary people.
