Biomechanical Analysis Of Consistency Of Badminton Player’s Spiking Motions, Such As Forehand Rubbing,Pushing,Hook

Objective:Regard eight high leveled badminton players of Beijing Sport University as the object of this research, and give a biomechanical analysis of their technolygy of hitting the ball, mainly including forehand chop, pushing the ball and hook the ball. Have a basic understanding of the rules and features of these three technologies, study their consistency and reveal the relation and difference among them. Meanwhile, the research can enrich and supplement the technological theory of badminton and provide suggestions and references for the training of badminton players.Methods:the infrared spot high-speed camera (250Hz) method of eight badminton men’s, putt and hooker technology to shoot, and upper limb movement angle, angular velocity and other parameters are calculated. According to the technical process in the racket frame characteristic velocity will be three kinds of technology are divided to shoot stage, after the racket and hitting the stage. Using repeated measures ANOVA analysis method of three kinds of technical parameters difference test and subsequent inspection using LSD method.Results:shoot stage rub, push, hook three technical action in time, in the shoulder, elbow, wrist, shooting the speed there was no difference, through arm angle changes can shoot the judgment whether the opponent has a putt the intention. The racket stage, rub the ball after the introduction of the shortest time, hooker and putt the backswing time no difference; three movements in elbow speed, beat box, speed does not have the difference, putt maintained faster shoulder velocity and wrist speed; three movements in angle of elbow and forearm pronation supination angle on a good putt the shoulder angle greater than ball rub, Hooker angle wrist, wrist dorsal flexion less significant in the, putting the shooting arm angle. In ball stage. In the hitting stage, three strokes except the elbow angle difference obviously, putt the ball time shortest; in the film frame speed from fast to slow in turn is putt, Hooker, rub the ball; putt the shoulder angle greater than hooker. Hooker wrist angle change minimum putt the wrist angle variable maximization; forearm supination pronation angle and shoot angle changes close to, rub the ball moves small arm of the internal and external rotation angle minimum; shot putt of shoot arm angle of the most obvious changes.Conclusion:1, the lead shot and hit the ball movement is closely linked, the different movement in the citation will appear the difference. Badminton athletes forehand rubbing ball, putt, Hooker action shoot stage except the racquet arm angle and there is a high consistency in, the racket began to appear consistency difference.2, battingswing process, different action back to the ball with the racket surface angle, small arm between internal and external rotation. Push action in the whole process by Guoqiu, overhead kick faster, more changes in range of motion. 3, suggest a ball on the racket in the front section of the consistency of action, before hitting the backswing movements are small and fast convergence, pay attention to explosive force, to sell quickly.4, game to hit the ball side of the wrist angle, take arm angle and shoot surface of, with particular attention to lead after shoot stages, and the judgment ability to bind to the training.
