The Characteristics Of Main Muscles Research On The Female Athlete's Shot Putter Song Jiayuan's Spinning Throwing Technique

In this study,we use the literature data method,expert interview method and experimental method to study the muscle exertion characteristics of the final force stage of the rotating shot put technique in the Chinese women's shot putter Wang Songjiayuan simulation game,mainly from the final push of the rotary shot put technology.The main aspects of the stage,the angle of each joint,the main muscles,the main muscles of the muscles were analyzed,revealing the muscle exertion characteristics of the Chinese female shot putter Song Jiayuan's rotary shot put technology,and for the future Song Jiayuan's special strength training proposed to strengthen the direction,provide a scientific basis for the application of women's rotary shot put technology in China,and solve the problem of future training in the Shanghai Track and Field Women's Shot Put project,which has important practical value.In order to improve Song Jiayuan's special technical ability,provide biological evidence;clear the special supplement direction,further improve the training efficiency,and ultimately promote the improvement of the special results of shot put.Research results: 1.Song Jiayuan uses the rotary shot put technique in the final stage of exertion.The running distance of the shot put is 169.33±2.31(cm),the shot shot speed is 12.61±0.32(m/s),and the completion time is 0.23±0.01(s 2;Song Jiayuan Rotary Shot Put Technique In the final stage of exertion,the time sequence of the three-dimensional velocity peaks in each key link is:(left knee-left 踝-left shoulder)-left hip-left elbow-right knee-center of gravity-right 踝-Right hip-right shoulder-right elbow;3,Song Jiayuan rotary push shot technique In the final exertion stage,the main muscle activation order with good test scores is: right triceps-left gastrocnemius-left lateral femoral muscle-right Lateral external oblique muscle-left external oblique muscle-right lateral gastrocnemius-right lateral femoral muscle-right deltoid anterior bundle;4,the final exertion phase,the right external oblique muscles are lower in the spanning segment The results are poor,and the results are better when the discharge level is higher.Research conclusions: 1.Song Jiayuan uses the rotary shot put technique in the final stage of exertion.The working distance of the shot put is similar to that of the world-class female athletes who use the back-pushing technique in China,and even has an advantage;but the acceleration ability of the shot put in the final stage of exertion There are still some gaps in other areas.2,Song Jiayuan rotary push shot technology in the final stage of exertion,the three-dimensional speed peaks of each key link appear in the order of time In general,the peak speed of the link appears in the order from left to right,from bottom to top.The combination of the throwing arm force and the right lower limb force,and the left side of the support shaft fixed force to substantially reduce the speed can basically meet the mechanical requirements;3,Song Jiayuan rotary push shot technology in the final stage of exertion,the important joints The change in angle is similar to the final stage of the female athletes who use the back-push shot technique in China.With the improvement of sports performance,the shoulder twist angle at the time of shot shooting is declining.At the same time,when the result of putting shots is good,the angle of change of the left knee joint is larger.It shows that the strengthening of the support legs and the control of the shots at the time of the shots are beneficial to the improvement of Song Jiayuan's sports performance.4,Song Jiayuan rotary push shot technology in the final stage of exertion,the left lateral gastrocnemius muscle,the right external oblique muscle is the main force of the Song Jiayuan rotary push shot technology in the final stage of exertion,especially the right abdominal external oblique muscles on the throwing results It has an important role;in three tests,the order of muscle activation is not exactly the same,indicating that Song Jiayuan's technical proficiency needs to be strengthened.5,Song Jiayuan rotary push shot technology in the final stage of exertion,the right main lower limb muscle discharge is insufficient(femoral lateral muscle,gastrocnemius muscle),bilateral knee extension muscle activation is not enough(femoral lateral muscle),indicating the final stage of exertion The lack of strength in the lower extremities is one of the reasons for Song Jiayuan's lack of acceleration in the final stage of the effort.
