Surface Electromyogram Characteristics Of Archery Basic Technical Movements And Core Stability Strength Training And Correlation Analysis

In order to explore the basic skill of archery electromyographic characteristics and core stability strength training methods of EMG characteristics and the relationships among them. Many methods have been empioyed to probe into this research,such as literature material,interview, electrodiagnostic testing method and mathematical statistics and other research methods.Fujian province sports team elite archery athletes as the test object, use American BIOPAC company production of the MP150multi-channel physiological signal recorder with synchronous camera on10Archer archery basic skill and core stability strength training method of electrodiagnostic testing.and use AcqKnowledge4.1analysis software combined with synchronous video on archery technical straps, upper limb and trunk muscles of the core muscles mainly integral electromyography, muscle discharge starting time and put some duration of electromyographic analysis. Summary of basic skill of archery and core stability strength training in shoulder, upper limb and trunk core muscles force characteristics, explore the relationships among them, evaluation of core stability strength training for rationality, technical improvement, and provide a theoretical basis for teaching and training. Conclusions of the study are as follows:(1)Archery in action, the bow lateral deltoid muscle, the bow contralateral trapezius muscle, the bow lateral deltoid muscle, drew the contralateral trapezius muscle, the bow lateral latissimus dorsi, the bow lateral refers to the shallow flexor and refers to the total extensor muscles for raised his bow, drew, solid potential and the main force muscle, trunk shaft spinal muscular, musculus glutaeus maximus, abdominal muscle and abdomen outside the oblique muscle muscle is to maintain a body dynamic balance of power.(2)Because of the male and the female athlete’s own biological characteristics, strength and technical movement characteristics advantage difference on the differences, lead to male, female athletes in every stage of the action and shoot arrows each muscle group action of integral muscle power, discharge start time and continuous discharge time of gender differences exist, movement performance for female athletes archery action a steady and fluent, the technology more rigorous, male athletes archery natural and fluent movements, a more casual technology.(3)Archery real shoot complete action and the stage of action of the bow lateral and the bow lateral corresponding parts muscle group of different, and part of the muscle group also gender differences in female athletes bow lateral shaft spinal muscular and musculus glutaeus maximus is mainly for balance when the bow of the body forward produce resistance moment and drew in stage of bowstring boycott essels force.(4)Without the destruction of the structure and action archery itself the fluidity of the premise, for bow at the time, fixed time, time and action potential total time length can only for the superiority of results provide a reference archery, but can not be used as archery action of quality evaluation index, revelation athletes and coaches try to development and the right, have obvious characteristics of the individual archery action.(5)National outstanding athletes shoot the movements of the integral muscle power level athletes than small, solid potential than level1player short time and as much of the arrow shot of grades than level good athletes, the athletes that high level of economy and efficiency of muscle power is relatively high, technical movement to automation, and correct effective make the action.(6)Dumbbell levelly obeying and dumbbell arm for can increase the related muscle group foundation power reserves, but can’t effectively and training and development archery movement of the core stability strength; The longest time drew the training is male, female athletes muscular endurance training base and effective methods of training, and highly correlated with archery action.(7)Kneeling balance ball raised his bow, drew training, the body in addition to balance for body weight when the bow and deviation when drew the bowstring essels force, had to overcome kneeling balance the ball is not stable produce body imbalances, can be very good exercise archery each muscle group action between balance and coordination and balance ability of the body.(8)Muscle coordination hard training of upright mention cubits pull, bow against birds, bow arm pull and bended body boating four method can effectively training each muscle group coordination hard, in addition to female athletes bow single arm pull, other action and archery real shoot action correlation is higher, can be used as a core stability archery strength training method.
