Optimal Selection Analysis On Women’s Javelin Special Strength With The Technique Of Surface Electromyography

Javelin is a complex multi-axis of rotation event, requiring athletes with high coordination ability and Great explosive power. Specific strength of Javelin is one of the important factors that improve performance. Enhancing athlete’s special strength is aperfect way to improve their achievement; Training methods are diverse. In order tomake special technology more perfect and get a better achievement, Selecting the best training methods to build female javelin throwers strength is necessary. which acquire us analysis the technical structure characteristics of javelin and select the most relevant special strength training methods.based on special strangth training of women’s javelin thrower, we selecet five elite javelin throwers as a study object. the use of surface electromyography technology test women’s javelin final stage of muscle force exertion order and the main contribution of muscle EMG, through statistics and logical analysis to obtain the final stage of muscle exertion force for order and the main contribution to muscle reference, application expert interviews, observation teams with research methods for special strength training means the collection and collation of special strength training means Preferably, get the women’s javelin project the most effective means of special strength training.Throwing heavy guns on stage cast iron ball, medicine ball with both hands, hand-held devices whipping, sit pull the barbell, barbell weight transfer rotating were selected as the opitimal six special strength methods. testingthesurface electromyography of 6 special means and find out power transmission chain and major force muscles, campare with power transmission chain of final stageThe optimal selected special strength are consistent with the sequence of exerting power, in line with the sequence of exerting force in large muscle and small muscle. the optimal selected strength mathods are also in line with the last major contribution to muscle the main stages involved in muscle force contributions. Training Means is not a single fixed, according to the technical characteristics of athletes, select the most optimalstrength training mathodsoptimization of Special Strength Training is to the special needs of athletes as a basis for, can really play the Special Strength Training effect.The optimal selected 6strength training methods can also improve technical training mathods, and the combination of several strength training methods are not only helpful to the coordination of different muscles but also can consolidate and improve the javelin technique.
