Table Tennis Forehand Fast Loop Drive And Anti Pull High Loop Technique Kinematic Analysis

Today,the loop technique is one of the important techniques of table tennis athletes must grasp.The anti pull loop technology,it has become a table tennis match,to effectively deal with the loop transition,one of the most important techniques for active,one of the core technology required is a modern high level athletes.Through literature research,experimental method,mathematical statistics and logical analysis,the infrared VICON motion analysis system for the main equipments in Shanxi Province,North Central University,6 elite athletes as subjects,the motion of the process of being anti pull forward and anti pull loop high loop two technical movements Based on the analysis of table tennis forehand.Pull forward loop and anti pull high loop technology action analyzed,obtaining the subjects of lower extremity,center of gravity,the kinematics parameters of upper limb and the racket,and find out the two kinds of technical movements,movement characteristics and the differences.This thesis aims to study the training and teaching table tennis ball pull loop of forehand action,to provide theoretical and practical reference value.And let the table tennis professional athletes and sports enthusiasts more fundamentally recognize the difference between the two,to provide a reference for subsequent research on the loop technique of table tennis movement.Research results:1.The power of being anti pull forward the loop and pull high loop two motion transfer sequence of ankle joint,knee joint,hip joint,and then after reversing the torso transfer first and then to the shoulder,elbow,wrist by hand to reach the final,and the racket,the forces acting on the ball.2.In the course of the campaign,before being anti pull and anti pull loop at high loop technology action right ankle bending action appeared obvious,two technical movements are starting from the right knee,the bending angle decreases.And after the hit,the right knee andhip extension phenomenon began to appear.3.An important tool for the body as the body kinetic energy transfer,torso torsion in technical movement plays a key role in the process of connecting.In reversed pull forward loop and anti pull high loop action,as the lower trunk link,plays an important role in the two action process that was reversed pull high loop technique,the trunk twist angle to trunk twist angle is greater than the reversed pull loop forward.4.In the racket stage,reversed pull loop technology moves forward upper extremity joints movement to a greater extent than reversed pull high loop movement,and in the swing stage after hitting the forehand pull the red loop with essential position mainly tend to be ahead,but reversed pull high loop technique the spatial displacement will follow through on the direction of the force,for front.5.After contact with the ball racket,the pitching angle reversed pull forward loop technology racket and ball movement will be greater than the reversed pull high loop action.
