A Kinematics Study Of Overhead Clear Of Excellent Young Badminton Players Of Jiangsu Province

In this paper, the use of literature, kinematics analysis, expert interview, mathematical analysis and logical analysis, sports biomechanics research methods athletes ages five 2001 Jiangsu adolescent male badminton team in the backcourt head the ball hit the lofty region to analyze technical movements, the athletes on the move to take place, and swing the racket hitting all sectors of the three stages of human motion parameters were analyzed to reveal badminton court after hitting his head area sports technology lofty goals characteristics, in order to guide future training coaches, athletes improve technical action reference.Objective:Badminton players on the field after his head hit the ball lofty technical movement kinematics analysis, the quantitative data technology and analysis to identify common problems young athletes this technique to analyze the crux to overcome the use of the technology difficulty grasp scientific and rational action essentials, mentioned fact warfare capability.Methods:In this study, two different specifications SONY1080i camera, shooting frequency 50HZ; subjects Jiangsu badminton men’s youth team five athletes (both right-handed), selected experts and coaches agree that one of the best action shots Research action video, complete the three-dimensional analysis, technical analysis of movement kinematicsAfter five athletes through the lofty head ball movement technology field Biomechanical analysis the following conclusions:1. Mobile phase to take place five athletes in general is not very different shoulder angle, try to control the shoulder angle between about 60° to 75 °, this will help increase the racket from the racket phase, thereby increasing the speed of the swing; elbow angle should be controlled between 50° to 60 °, oversized elbow angle is not conducive to whipping action when the racket is completed; take place when on the move, Li Xiang, Liang Yongwang, Wang Cheng core focus of rising trends in the first decline until a basic level surface undulations and the larger focus of Wang Xincheng and Xu Junyan.2. racket stage five athletes hip angle decreases, torsion angles were 4.689 °,5.693°,2.167°,4.421° and 9.244°, reduced marginally, indicating insufficient tread turn; shoulder angle gradually increased knee angle right and left lower extremities were gradually increased, and the left knee angle greater than the angle of the right knee3. batting swing phase, Li Xiang’s swing fastest, reaching 32.983m/s; sequential upper right side of the maximum speed of each link to appear hip shoulder-elbow-wrist-finger-racket, this sequence of activities in line with the principle of whipping...
