Which Influence The Stability Of Men Ballroom Static Frame Type Main Electromyography Characteristics Of The Research And Training Methods Of Mistakes

Dance ballroom frame type is relatively fixed,it is associated with process stability,is the important factors that affect performance.The study adopted the method of documentation,expert interview method,measuring method,questionnaire survey method,experimental method and mathematical statistics,influence the man ballroom frame type main muscle and the analysis methods of EMG signal feature,and then according to the expert interview,questionnaire survey and the observed results,further discuss the standard frame type training methods,for comprehensive analysis and correct man type rack to provide scientific theoretical basis,also for our country sports dance science research methods provide feasibility reference material.Ballroom tango in special type,this paper only studies with relatively consistent waltz,Viennese waltz,foxtrot and quickstep frame type static conditions.The main results were as follows:1.Contrast two good men at home and abroad of the two arms bend ancon standard point of view,the results showed that the left arm elbow flexion at about 116 °to 134 ° or so,around the right arm elbow flexion Angle 100 ° to 105 °.Within this range,the higher the level of the player the elbow flexion Angle is relatively small.No matter what is the point of view,should keep the arm line space is open and shoulder straps of relaxation.2.From the mechanical point of view,men ballroom frame type belongs to a kind of static balance,in the case of not load maintain a fixed posture,muscle isometric contraction.From the view of anatomy,men ballroom frame type action structure in human anatomy structure of lateral flexion,two arms show the elbow internal rotation and shoulder abduction.3.The test results show that the standard frame type movement,the muscle activity began to order as follows: the deltoid muscle-trapezius muscle-the latissimus dorsi to triceps,biceps to pectoralis major,sternocleidomastoid;Deltoid,trapezius muscle,the latissimus dorsi is most main;And the end of the sequence is: the sternocleidomastoid biceps and triceps to pectoralis major,trapezius muscle to the latissimus dorsi,deltoid,sternocleidomastoid,end of the first discharge deltoid finally end of discharge,Sustained length of time the order is: the deltoid muscle and triceps to the latissimus dorsi,trapezius muscle to pectoralis major,biceps and sternocleidomastoid,deltoid muscle activity longest;Strength situation of deltoid muscle force is the largest,the latissimus dorsi times,second triceps and trapezius muscle respectively,sternocleidomastoid is minimal.Visible,deltoid,the latissimus dorsi,triceps,and the muscles of the trapezius muscle is one of the main.4.The methods of electric experiment for reference,combining the result of the questionnaire and the observed and the expert's advice,to a man ballroom frame type training methods from two aspects of general strength training and special strength training carries on the preliminary discussion,for players and coaches in training for the feasibility of reference.
