SEMG Analysis Of Muscle Biomechanics On The Characteristics For Outstanding Spin Shot-putter

Application of remote sensing image analysis with electromyography, shot put spin on domestic outstanding athlete Zhang Jun to actual state of the field testing, movement analysis of the technology, its current strength training tool for diagnosis. Issued separately from the main power of the muscles, the main force of muscle force issued the order, forced the scope and power of the major muscle-fat relationship between the coordination of research, found that their technical problems in movement, while according to his own force to design a number of characteristics specific strength training methods, so as to improve its technology, to assess their strength training to improve their throwing results provide theoretical basis for physiology, and also to learn from the same research methodologyThe results:1 a single-support phase of the major hair Zhang Jun Li left leg muscles play a supportive role of the muscle (vastus lateralis left leg and left leg medial gastrocnemius), and Rotate the body can produce muscle (right back width muscle in the central and right leg vastus medialis muscle). Made during the transitional stage will focus on muscle strength is under pressure from the role of the left leg muscles (biceps femoris and left leg left leg medial gastrocnemius), and will soon provide energy for the final stage of the physical exertion the right side of the muscles (right latissimus dorsi Central and the right leg lateral gastrocnemius muscle). The main force in the final stages of hair is left leg muscle power play a supportive role of the muscle (left leg biceps femoris, gastrocnemius medial left leg and left leg vastus lateralis) and the exertion phase of the final source of energy for the right side of the body muscles (right latissimus dorsi and the lower right leg lateral gastrocnemius).2 Zhang Jun single supporting phase two major power muscles forcefully made the order (left leg medial gastrocnemius→→right leg, left leg vastus lateralis vastus medialis on the right latissimus dorsi muscle→Central) is based on bottom-up, from left carried out to the right. Issued during the transitional stage will focus on the order of strength of muscle force (right leg, the right latissimus dorsi muscle gastrocnemius →→→left leg biceps femoris on the right latissimus dorsi Central) made a power of the order is a power from bottom to top, from right to left the transfer process. The main force in the final stages of hair strength muscles forcefully order (right leg, left leg gastrocnemius gastrocnemius→→→right side of his left leg vastus lateralis latissimus dorsi), made the order is a power of strength from right to left, bottom-up pass process.3 Zhang Jun in single-support phase of the main fat in muscle strength, so that rotation of the body muscle in a smaller range, leaving the muscles of the body play a fixed role in the scope of a larger force. During the transition period need to restrict stretching left knee, left knee can not be over-stretched straight, but should increase the left hip range of motion, as far as possible to open the left hip. The body in a relatively complete the final stretch of the state to force action. In the final stage of force should not be over-extended left knee, left knee can not be over-stretched straight, but should increase the rate of knee extension, as far as possible to open the right knee. The body in a relatively complete the final stretch of the state to force action.4 Zhang Jun in a single muscle in his right leg supporting phase coherence is not good,active muscle (right leg vastus medialis muscle), made when the antagonistic muscle forces (right leg biceps femoris) did not timely relaxation, affecting their muscles do work in the overall effect. Muscle in his left leg during the transition phase coherence is not good, active muscle (left leg quadriceps), made when the antagonist muscle strength (left leg calf muscle) did not timely to relax, thus affecting the overall effect of their muscles do work. Force in the final stages of coordination of muscle in his left leg is not good, his right leg muscles when the left leg muscle strength (mainly the left leg calf) failed to meet a good right leg muscle coordination hair strength, affecting the overall effectiveness of their muscles do work.
