Excellent Male Judo Athletes Seoi-nage Techniques With Sports Anatomy,sEMG,and 3D Kinematic Analysis

Research purpose: Through the literature review of judo seoi-nage techniques,previous researches have used the techniques of tactics of seoi-nage by watching the game or the video of the game.Relatively few,there is no analysis of kinematic anatomy movement analysis,muscle force characteristics analysis,regularity analysis of the movement of the backpack technology.Therefore,this study intends to analyze the action anatomy of the judo seoi-nage technique,the electromyography and dynamic characteristics of the forced muscles,and explore the action characteristics,objective laws,and force characteristics of the major muscles.Athletes and their coaches provide scientific theoretical basis in the standardized and standardized training of seoi-nage techniques.Research method: This paper adopts the research methods of literature,expert interviews,experiments,and mathematical statistics,and takes the seoi-nage technical movements of eight outstanding male judo athletes in the Chinese Judo National Training Team as the research object.Through experimental design,the anatomy analysis of technical movements in sports anatomy,surface electromyography testing,and sports biomechanics are used.The experimental method of three-dimensional kinematics test in this paper collects subject’s movement law,muscle electromyography,and related parameters of kinematics for statistical analysis.Research conclusions: 1.The law of movement of the backpack technology conforms to the laws of mechanical movement between various parts of the human body,and Archimedes’ leverage principle is used in the process of exerting force.2.Piggybacking technology moves The upper limbs’ muscle activation is the earliest,the most mobilized,the longest duration,and the highest contribution rate in the upper step phase,the induced hand phase,and the step rotation phase.3.To improve the athlete’s turning speed and grasp the turning timing during the process of seoi-nage technology has become the key to the successful execution of seoi-nage technology.
