Kinematic Analysis On Forehand Loop And Forehand Technique Of Excellent Table Tennis Athletes In Jilin Province

In this paper, three-dimensional images of the measurement method, the imageanalysis method, mathematical statistics and other research methods, are used tocapture and analyze the image of the six outstanding table tennis players in JilinProvince forehand attack ball technology and forehand loop drive technicalmovements, and to obtain relevant kinematic parameters of mathematical statistics.Combined with sports biomechanics and physiology and anatomy knowledge andresearch methods kinematic parameters for the analysis and comparison of twotechnical movements of the athletes of the shoulder joint angle, elbow angle, kneeangle, hip angle and body weight shift reveals two kinematic characteristics, providesa theoretical basis for the universality, improvement and enhance of these twotechnologies.The study shows that the forehand attack ball racket and restore are faster thanthe forehand loop drive fast ball; there is no big difference between the time usedduring the swing phase; the rate of forehand with play stage time is more than that ofloop time. In the course of the racket, elbow angle stretches to the maximum, but cannot fully straighten. At the same time, the the forehand attack ball movement elbowangle is significantly smaller than the elbow angle forehand loop drive action. Racketstage forehand loop drive action reduces the magnitude of both sides of the hip angle,and knee angle athlete legs are buckling squat state. In course of racket swing, elbowis used to do rapid flexion movement. The change of forehand loop action in kneeangle and hip angle is larger than that of forehand technology in this stage. In theprocess of forehand loop drive technical movements and athletes put the inside of theright foot palm pedaling to the body’s center of gravity shifted from the right side tothe left in the swing phase. Then during the restore process, the athletes pedal thefocus back to the right. However, the degree of movement of the center of gravityfrom left to right are larger than that of the forehand loop.
