| Sanda is an important part of martial arts is an art of attack and defense each other to the other side of the battle moves to transfer more than the confrontational skills events."Sanda two are in accordance with certain rules,the use of martial arts kicks,fight,fall and defensive techniques,such as to carry out unarmed confrontation of modern competitive sports." Sanda sports art of attack and defense competition into the world stage,the use of scientific research means to be further developed,at present,because of the scientific combination of equipment and training is not sufficient,means of modern scientific research has led to studies related technology moves less,to a certain extent affected the development of Sanda exercise.After the turn before Wushu sports are an important method of one of the legs,it mainly turned, after the leg,before playing the main stage of sports.After the action suddenly turned backs kick strong,fast,powerful,combat range,at Sanda confrontation played a surprise attack can hit the opponent's role as an athlete Sanda important in the fight against the opponent hit a one paragraph.Looking at Chinese Wushu Championship Wang,is not difficult to see after turning kick leg are the most powerful method,one person before the research literature of view,at "the fourth East Asian Games," Sanda game site photography,video game through the analysis of the use of leg techniques to conduct a study found that:turned back kickin this game use the number 20 times,using the rate of 3%in the number of successful 7 a success rate of 35%of the total average score of 0.70 points 14 through legs of the comparative analysis method to use turned back kick Although low utilization,but a higher success rate.Sanda Wang in 2000 race for hegemony,zheng yu's used turned back kickvacated after turning down the other side,lying on the ground of their profession can not afford the famous town of Sanda.2003 Sanda Wang won hegemony,Victor strong at the same day evening,and after turning down two consecutive turned back kick athletes and win. However,turned back kick low utilization and high-risk,in order to give better play to turn around after the game turned back kick at Sanda strengths and improve the frequency of use, this paper,literature,video cameras filming the scene law,video analysis method, mathematical statistics,as well as expert consultation law,the application of three-dimensional image analysis system for Hebei Province Sanda outstanding athletes turned against sandbags after turned back kick carried out the whole process of treatment and analysis,research turned back kick technology after the turn of the law of action to identify successful completion of the main factors action.Access to a number of more comprehensive indicators of human kinematics and parameters,from the aspect of the exercise track characteristics,the characteristics of the various aspect of the speed,angle changes in the characteristics of the kinematic point of view,qualitative and quantitative indicators of access to and the parameters more comprehensive and systematic analysis of Hebei Province Sanda outstanding athletes turned turned back kick skill after the basic kinematic features of movements:from shoulder trajectories of hip and shoulder angle curve of the hip,the shoulders of the sport ahead of the characteristics of a rotating the situation,turned around turned back kick skill moves the human body has large aspect-trunk participation in sports in order to generate greater momentum;swinging leg from the hip,knee,foot trajectory characteristics and speed characteristics,the leg exercise activity chain sequence are from the aspect of small aspect,and then one by one and instantaneous braking;turned back kick technology after turning movement speed characteristics also shows that the leg followed by increasing the speed aspect,there is a movement of the whip;in the fight against one of the sandbags In an instant,hit the speed of the largest toe,athletes have a big leg folded-to open-the process of whipping,folding action are in order to reduce the rotation radius, rotation speed increases,thus can effectively increase the leg extensor action aspect of the end of moment of momentum,and enhance the beating effect.Of Hebei Province Sanda outstanding athletes turned turned back kick technology after the three-dimensional kinematic features of action research,reveals the Sanda turned back kick technology after turning movements and characteristics of sports law for the diagnosis,to improve and enhance technical turned back kick movements and Sanda teaching and training to provide a reliable and quantitative analysis of kinematic parameters,scientific,systematic,in-depth analysis of skill turned back kick,so as to more accurately study finished behind turned back kick, formulate a technology turned back kickafter turning movements and provide a theoretical reference and evaluation indicators,and thus guide Sanda athletes in teaching,training and competition in the application of technology to promote turned back kick action after turning scientific training,and improve the current technology mined back kick action after turning teaching and training methods,the guidance of teaching,training and provide objective basis. |
