Research On The Archery Action Comprehensive Test And Technique Evaluation Index

Archery has a long history in China.However,since China's participation in the Olympic Games,its archery hasn't won the first prize.The main reason,no matter from the angle of game training theory or the comparative analysis of the archery in Korea and China,that China hasn't won a gold in archery in the Olympic Games is not the result of race,economics or the system,but the result of the insufficient understanding of theessence and law of the archery,lack of systematic and scientific training system and the low training efficiency in China.Based on the documents and inquiry of experts,the author finds out that the main reason of the unsuccessful achievement in China's archery is because of the low mastery of the action technique.There is a small action range in archery.Simple methods and analysis is inadequate,so the author,on the basis of testing the archery athletes in national team with the Qualisisy infrared photoelectric testing system,Footscan sole pressure testing system,Noraxon myoelectricity remote testing system, etc,analyzes comprehensively the action technique of the athletes in national team from the posture,body motion characteristics,body posture equilibrium and stability,distribution of centre sole pressure, myoelectricity characteristics,etc,with the methods of relative software and data statistics.The conclusions and the suggestions are as follows:Conclusion:Firstly,the communality of posture angle,muscle strength,the activation order of main muscle during raising the bow, raising the bow and the timing of the raising could be used as the evaluation index of technique action in archery;Secondly,the length of the time needed in the different periods couldn't be used as technique evaluation index since it has no relation with the result.But the time of raising and pulling back the row is relatively fixed,and the time has a positive relation with the archery achievement of the national team in China.Thirdly,the central index of the sole pressure could be used as the reference criterion of selecting athletes and forecasting achievement.During playing archery,the interrelation between the central index of the sole pressure and the achievement is different individually and in different periods.Fourthly,there is low stability of the archery athletes in the front and back direction during the action, caused by the athletes' posture disequilibrium of dorsal abdominal muscle and non-professional sport shoes..Fifthly,kinematics and electromyography shows that the people on archery in China haven't taken the raising and pulling back the row seriously.And there is no absolute character in the back muscle and low rationality in the action technique.Suggestion:Firstly,fast rhythm is the character of only some individual;therefore,we should put the emphasis on the action quality. We shouldn't emphasize too much about the fast rhythm because of the shortened time for the preparation for the team competition.Secondly, the athletes should adopt the vibration training method or the strength training method with unstable supporting surface.Because these two methods can not only activate motion element which couldn't be activated in most of time,but also add up the harmonization of the nerve muscle and make the proprioceptor trained.Thirdly,we should make or choose special archery shoes which have slip-resistant sole and suitable degree of bend in the front and back,suiting for the competition ground and adding Up the stability,fourthly,we should properly pay attention to the stage of lifting.
