The Research On The Technical Movements Of The Dominant Side Of The Boxing And Leg Of The Excellent Male Athletes In Free Combat

Using the method of literature and expert interview,this paper draws a conclusion that the competitive Wushu Sanda technology has finished the unstandardized state in the theoretical textbooks,concepts and rules,and realizes the unified standard of theory,practice,rules and competition.Through the method of video and expert interview,the scoring rate of the preparatory posture,the left kick,the right leg,right whip leg,right punching fist and right-hand hook is higher than that of the different side.Therefore,the five techniques based on the preposition are established as the action of the dominant side technology.Through the experimental method,it is found that the time characteristics of the advantage side boxing and the leg technique,the angle of joint,the speed of the center and the velocity of the center of gravity are the key factors that affect the completion of the technology.Through the analysis of medium level athletes left kick,kick right and the right players technical time characteristics can be found: technology of the shortest total time used to kick on the left,the average available for(0.92 + /-0.33 S);The second is the right kick,the average time is(1.20 + 0.32 S): the longest technique used is the right leg,the average time is:(1.41 + 0.38 S);Based on the analysis of the athletes at the same time make the action when the Angle of the hip,knee,ankle flexion and extension and changes in the rate of center,on the basis of control of the athletes leg ability,the rationality of the recovery of leg when placement for monitoring and evaluation.In right strike(technical analysis of characteristics of time that medium level athletes(in addition to the maximum level athletes Chen Yanzhao),in the punch and the closed fist stage when there is no level strictly,the use of the fist time parameters associated with the technical level of athletes;In whipped punch right elbow Angle analysis,athletes baryal and Huang Lei biggest hits the nose before stage elbow Angle is 141.79 ° and 127.50 ° respectively,and in the right whip boxing the least time consuming both time consuming and can explain whipped boxing punches in the right face when you arrive at the nasal side before elbow Angle slightly larger whipped boxing technology is good,because in the dynamic torque(arm length)under the condition of fixed Angle of elbow slightly ambassador punch surface body is far away,can produce a larger moment of inertia of the body,to make the action faster.Advantage for the common features of side kicks: left leg and right leg fast forward yi,both can increase the kinetic energy of the body and can adjust the range of left and right leg,left and right side of the supporting leg forward of gait lift a leg at the same time,the center of gravity forward,the Angle of the supporting leg small changes,is conducive to the stability of the supporting leg and support stability to complete the action.The characteristics of the dominant side boxing are: the right punch and the right chucking punch are not very different,the two are fast,the action is long and the impact is big,it is heavy boxing.Strike(right after the swimmer is to pedal to get reaction produced by rotating the hips twisting force to push the rate at which the body move forward,pass on the shoulder,the penetration in the arm,arm can promote the forearm,from bend to stretch,spin out,put boxing peak,the overall coordination of power so as to achieve speed and power integrity;Whipped the power characteristics of boxing is to make the right hip,twisting the waist shoulder and raise the shoulder,elbow drive fist forms two acceleration to work together in the boxing,keep the elbow right Angle,can not be too big or too small.
