Kinematic And SEMG Characteristics Analysis Of Back Court Smashing Technique For Young Male’s Badminton Players In Tianjin

Badminton is one of the athletic sports which generate the most gold medals inOlympic games, world championships and other major world competitions.In recentyears, Chinese national badminton team gets excellent performance in thesecompetitions, the competitive level is in a leading position in the world.Badmintonback court smashing Technique is one of the important means of scoring backcourtdirectly, Teenagers are the reserve force and successors of the national team and thepowerful guarantee of keeping keep a high level of national competition.Therefore, thisresearch is to study with literature data, image analysis and other methods, based onexperiments.Doing quantitative analysis of Tianjin Young male badminton players’Badminton back court smashing technique.Exploring the spacial movement analysis&the surface EMG characteristics of main muscles in the process of Badminton BackCourt Smashing. Finding out the technical problems, training to better the specialtechnical. To enrich the scientific study of kinematics and surface EMG in YoungBadminton technical aspects, moreover provides the theory reference for the technicaltraining of Junior Badminton Players in china. The study results as following:1.According to the change of the body center of gravity and the Movement structure.Divide Badminton Back Court Smashing Technique into3stages from feet free fromground to Single foot touchdown instant.1-feet free from ground to The highest pointof center of gravity、2-The highest point of center of gravity to instant hit、3-instant hitto Single foot touchdown instant.The first、third stage for Tianjin Youth MaleBadminton Athletes is too long, The third time period of time to grasp the better,Overall time is long, slow action.2.The action of Tianjin young male badminton players’ backcourt smashingtechnology is reasonable. But Extension amplitude of the max angle of the knee joint,Hip joint,shoulder, elbow is not extended fully.during the process, Resulting in lowhitting point, affecting the integrity of the action and batting performance and ballspeed. The time period between the moment of maximum speed of elbow joint,wrist joint to the moment of hitting time is short, but the maximum velocity is small. 3.There is big improvement space for racket speed&ball speed during the process ofTianjin Young athletes badminton back court smashing technique movement.4.There must be more muscle involved during the movements of Badminton BackCourt Smashing Technique.such like Deltoid muscle in the beam, triceps, trapezius,biceps and its nearby muscles. Training to strengthen the muscles&Develop the rapidcontraction.There is important significance to improve the athletes technicalRationality, Economic effectiveness&success rate.
