Badminton Backhand Lofty Goals Of Biomechanics Analysis Technology

Badminton backhand after the field lofty goals during the game technology is a badminton field technology after the technology is relatively high utilization rate movements. Especially for high-quality amateur backhand shot is a lofty ball technology can not only resolve the situation and give each other a passive cause some psychological pressure. In this study, literature, expert interviews, three-dimensional high-speed camera, the method of EMG test badminton backhand technology field after the kinematics and electromyographic study, the results of the hair bulb of the teaching, training and competitions practice with guidance. Lofty backhand ball technology can be divided into four areas to determine the basic movements start, turn the racket moving, hair force hit back to the pitch. This study through a combination of kinematic and electromyographic analysis technique reveals the backhand all the major muscle movements the human body mass and muscle to exert force of circumstances and sports links in chronological order and characteristics of space law:1 Badminton backhand ball technology lofty upper part of each exercise in order to show acceleration and braking, speed is movement from the proximal part of the body to a remote part of gradually increased exercise, and finally by hand on the Control of the racket to racket hit the ball before the maximum velocity.2 Badminton backhand lofty goals of rapid technological leg kicking forward key to get the hip upward velocity, can reverse the accumulation of power in order to pass the trunk to the shoulder, elbow, bowls, racket, finally passed control of the wrist to hit the ball quickly After each field within range.3 Discharge of the racket when the muscles in order to "shoulder-elbow-wrist," swing the discharge when the muscle in order to "lower limb-a waist of a shoulder elbow wrist of a" power and speed in order to complete the transfer, the final complete the swing.4 Deltoid muscle (the beam), trapezius badminton backhand lofty goals to accomplish a major force swing muscles.
