Elite Table Tennis Players Ma Long,Fan Zhendong Backhand Technique And Bio-mechanical Features

This research adopts the research methods of sports biomechanics,the world’ s top table tennis players Malong,FanZhenDong,use of video image analysis system and a high-speed camera to two athletes at the completion of a shake hand grip backhand technology in motion the process of testing and data processing,and then through such means as Q-tools software for data calculation,get two complete sets of table tennis athletes of backhand technique in the trunk,upper limb and lower limb joint three-dimensional biomechanical indexes such as Angle and angular velocity,acceleration,and combining with the sports biomechanics,sports anatomy,sports training and sports statistics,and so on.Reveal Malong,Fan ZhenDong two athletes shake hand grip backhand twist in technical movement kinematics characteristics,compare again,so as to guide the athletes more reasonable and effective use the techniques,also for coaches in training in the future teaching,diagnosis,the technology to provide theoretical reference.This research mainly draw the following conclusion:(1)Fan Zhendong backhand twist technology is advantage in technology,and Ma long’s backhand twist technology is not to advantage games rarely directly using the game score,Fan Zhendong backhand twist technology more than Ma long handle within the technical threats;(2)backhand twist of basic technology action:introduction took stage,right feet to right mobile of while,torso Qian pour and left reverse,gravity to right leg Shang mobile,lower limb micro-flexor,selected bit end Hou right shoulder Shang mention,arm lift up、forward top,forearm within received and within spin,wrist flexor to wrist joint angle reached minimum,At the up end of the racket to the ball.Waved took stage,racket main forward,and left above accelerated movement batting,wrist accelerated stretch waved took,to elbow joint for axis forearm accelerated to outside exhibition led big arm and right shoulder slightly sinking,torso continues to left reverse to batting Qian,torso accelerated right reverse up movement,lower limb pedal stretch punches,non-practice took side upper limb and practice took side upper limb anti-direction accelerated movement,in to ball declined early batting.
