Research On The Application Of Turning Technique In The National Men’s Sanda Championship

Sanda originated from traditional martial arts,and its technique is a technical system formed by refining and integrating the essence of kicking,hitting,throwing and grabbing in traditional martial arts.With the evolution and development of Sanda techniques and tactics,the research on the commonly used techniques such as straight swing hook,whip kick and so on has become saturated at present,and it is difficult for athletes to further improve the use of fist and leg techniques,so the potential of difficult new techniques need to be further explored.Which turned and technical characteristics of the Chinese martial arts,to highlight the charm of Wushu Sanda,it attack range,strong lethality,hit effect is obvious,properly can get surprise effect,often be in the game played down the drama of the opponent to win victory,with a "winning formula" the laudatory name,is not only turned to such technology also has high ornamental,Every time a player hits an opponent,he gets a house full of applause.In spite of its obvious advantages,its utilization rate is not high in Sanda competition,and the reasons remain to be further explored.Turn class technical data in the study of most from the perspective of biomechanics,the people’s perception to turn such technology is relatively shallow,based on this,the author by observing man in national Sanda championship in 2018 and 2019 1/16 final to the final video,use of game player turned class technical statistics and analysis,In order to understand the rules and characteristics of athletes using the turn technology,analyze the advantages and disadvantages,find out the reasons restricting the use of the turn technology,in order to enrich the martial arts Sanda technical and tactical system,to provide scientific and reasonable suggestions for coaches and athletes,and further promote the scientific development and effective dissemination of Wushu Sanda.In this paper,three kinds of turning techniques,such as whipping fist,swinging leg after turning and kicking leg after turning,are studied by means of literature,video observation,interview and mathematical statistics.The results show that:(1)In the use of all kicking techniques,the success rate from high to low is as follows:kick after turn > whip > turn whip > kick > side kick > straight punch > swing fist > hook fist > swing leg after turn.The success rate of the three kinds of turning techniques are 30.2%,26.9% and 6% respectively.(2)The order of the number of kicks used by athletes of different levels after turning around is middle level > small level > large level,and the order of the success rate is small level > middle level > large level from high to low,and the data are 32.3%,28.9%,27.2%respectively.The order of the number of use of turn whip from high to low was: medium level > small level > large level,and the order of success rate from high to low was: small level > large level > medium level,and the data were 38.4%,27.2% and 21.4%,respectively.The order of the use of swing leg after turning from high to low is: small level > medium level > large level.Only the medium level has been successful,the success rate is 13%,and the other levels have not been successful.(3)Turning whip and kicking after turning are mainly used in active attack and defensive tactics after active attack.Among them,in the active attack tactics,the combination of whip +turn whip,kick after turn + turn whip is better,and the combination of straight punch + kick after turn,whip + kick after turn is better.In the defensive and counterattack tactics,the success rate of whip and kick is higher,while the other two techniques are less effective in the defensive and counterattack tactics,showing low utilization rate and low success rate.Turning back swing leg is mainly active attack tactics,the other tactics are not good.(4)The three turn techniques were used more frequently in the finals from 1/16 to quarterfinals,but less frequently in the semifinals and finals.Among them,the use of turn whip was mainly concentrated between 1/16 and 1/4 finals,and the use of turn kick and turn swing legs showed a step downward trend in different rounds.(5)Nowadays,the top three(elite level)athletes and the top five(level 1)athletes account for a large proportion of the success cases of turning techniques.Research Conclusions:(1)The kick after the turn and the whip after the turn have a higher success rate than the commonly used punch-and-kick techniques,both of which have TKO cases.The use effect of swing leg after turn is generally poor.In all kinds of tactics,the use of turn whip is relatively average.In the defensive counterattack tactics,the kick kick can limit the opponent’s movement and become the key to hit the opponent.The turn and kick only works best in the active attack type.The more abundant the combination of the three kinds of turning techniques,the better the hit effect,but the combination of use is not universal,most athletes’ technical level has not reached the requirements.(2)Athletes are affected by their weight when using the three turning techniques.Among them,the junior level athletes are restricted by the fast rhythm of attack and defense as well as diving and leg throwing,while the senior level athletes are mainly restricted by the movement ability.(3)The athlete’s own technical ability limits the use of the three turning techniques.The effect of the three turning techniques is very polarized,and the successful cases are mainly concentrated in the elite athletes.Elite athletes can create conditions for the use of turn techniques by cleverly using combination techniques or by using leg catch to restrict the opponent’s movement,while other ranking athletes lack the ability to create opportunities for the three turn techniques,and most of them gamble with the three turn techniques before the end of the competition.(4)The single tactical execution ability of athletes restricts the use of three turning techniques.The main performance is: the lack of the ability to create conditions for the attack in the active offensive tactics;The main reason that restricts the athletes in the defense and counterattack tactics is the kick fall.(5)The opponent’s skill level limits the use of the three turning techniques.The closer the opponent is to the strength,the lower the utilization rate will be.If the opponent is good at throwing and defensive counterattack,the athlete will be more restricted to use the turning technique.(6)The current Sanda competition rules limit the use of the turn technology,and the current Sanda competition rules do not provide high scores for the turn technology,which is not conducive to guiding athletes to increase the application of the turn technology.
