Study On The EMG Characteristics Of Different Archery Techniques For Archery Beginner Compound Archery

Research purposes: This article compares the myoelectric characteristics of archery beginners with straight arched archery and arched bow archery techniques for archery beginners.It aims to provide a theoretical basis and technical guidance for beginners to learn compound bow archery techniques.Improve learning and prevent sports injuries.Research Methods: This article uses literature analysis methods,questionnaire survey methods,expert interview methods,experimental methods and mathematical statistics methods.Using the COMETAC wireless electromyography test system and VICON 3D infrared high-speed motion capture system,14 subjects underwent simultaneous acquisition of 12 electromyographic data of 12 muscles of 12 upper extremities under two archery techniques.Bow stage data were compared.Research results:(1)Muscle exertion during arching: There are statistically significant differences in the contribution rates of 7 muscles in 12 muscles of both arches.Respectively,the bundles of the deltoid muscles of the deltoid muscles and the arches of the arches were held(P<0.01).The anterior bundles of the deltoid muscles,the biceps brachii,the triceps brachii,and the arched arms of the arched arm were held.Head and deltoid muscle beams(P<0.05).(2)Muscular force in open arch: There are significant differences in the integral electromyographic contribution rates of 3 muscles of 12 muscles of the two open arches,namely the triceps brachii and biceps brachii(P).<0.01)and mid-trapezius trapezius muscle beam(P < 0.05).(3)Consistency of muscle force during arching: The arch force of the two arched arms is different from that of the muscles of the arch arm and the pull arm.There was a significant difference in the coefficient of variation of the lower bundles of the trapezius muscle,the triceps brachii muscle,and the pullbow arm lateral muscles(P<0.05).(4)Consistency of muscle force in open arch: The consistency of the muscle force of the archarm side and pull arch arm side is different between the two open arches.There was a significant difference in the coefficient of variation of the triceps brachii and biceps brachii muscles(P<0.05).The research conclusions are as follows:(1)In the bow archery archery course,archery beginners have bow arches in early stage of bow arching,holding the bow arm flexion angle at random,and insufficient mobilization of back muscle during the arching phase.(2)Archery beginners have lower consistency in muscle strength than professional athletes,whether they are arching or bowing.(3)Archery beginners in the composite archery archery process,the two archery techniques in the arching stage and the arching stage of the main force muscles are different,the biggest difference is the biceps brachii and triceps brachii The contribution of the action is different.(4)Archery beginners in the compound archery archery process,whether bow raising stage or open bow stage,beginners straight arm open bow archery technique muscle consistency consistency is higher than the bending arm open archery technique muscle consistency.Therefore,it is recommended that archery beginners in the process of compound bow archery learning or training,to strengthen the specific strength exercises of the deltoid muscle,triceps brachii and pull the back arm muscles,bow control during lifting the bow.The flexion angle is relatively stable,and the back muscle force is consciously deployed in the process of pulling the bow;the straight arm open archery technique is selected as the entry technique for compound bow archery technology learning;reasonable guidance for two different action stages or two different archery techniques is reasonable The corresponding main force muscles are deployed.
