Kinematic Analysis Of The First Wood Full Swing Technique Of Elite Men’s Golfers From China,Japan And South Korea

Research objectives: Through the three-dimensional kinematic analysis of the swing skills of Chinese,Japanese and Korean elite men’s players,the similarities and differences of the swing skills of Chinese,Japanese and Korean players are found,which will provide theoretical support and help for the improvement of the skills of Chinese and Japanese golfers in the later stage,and at the same time provide certain reference value for the development of scientific and reasonable training content for the youth golf training.Research methods: This study used literature data method,three-dimensional high-speed video method(1000 frames per second),three-dimensional video analysis method,interview method,mathematical statistics and other methods.Three dimensional kinematic analysis is carried out on the first wood swing technique of outstanding men’s players from China,Japan and South Korea participating in 2019 HSBC Champions.Research results:(1)There is a significant negative correlation between the players’ right knee Angle at the time of preparation and the take-off Angle.(2)There is a significant positive correlation between the joint angles of the body and the hitting distance and the take-off Angle in the ascending stage.(3)There was a significant negative correlation between the time spent at the end of the stroke and swing speed and ball speed,and a significant positive correlation between the Angle changes of each joint and swing speed and hitting distance.(4)The shoulder rotation Angle and the relative rotation of shoulder and hip at the moment of hitting are significantly positively correlated with swing speed,and the moving distance of the body’s center of gravity on the Y axis at the moment of hitting is significantly positively correlated with swing speed and ball speed.(5)There is a significant positive correlation among swing speed,ball speed and hitting distance.Research conclusion:(1)At the moment of preparation,the stance of Chinese players is more inclined to the open state,while that of Japanese and Korean players is closer to the parallel state.There is a big difference between the stance of Chinese players and that of Japanese and Korean players.(2)In the ascending stage,the shoulder-hip integration of Japanese and Korean players is better than that of Chinese players.(3)In the lower stroke stage,Chinese players use less time to swing and have better delayed release ability,which makes Chinese players swing faster,but because of too fast,the batting efficiency is low,so that the batting distance is relatively short.(4)The moment of hitting,under certain conditions,the greater the relative rotation Angle of the shoulders and hips,the torque between the body will increase,thus increasing the swing speed.(5)Chinese players swing faster,which will reduce the batting efficiency and the success rate of batting.
