A Comparative Study: Technique Between Rubber Rod Throw And Javelin Throw On Final Thrust

Rubber rod throw is one of the strength training measures about javelin throw which throw less weight rubber rod and is the same as javelin throw by means of approach run,throwing pace and final thrust. This measures belong to the area of javelin strength training as same as grenade throw,different weight of solid ball throw and javelin throw.With the development of javelin throw level ,the strength training take an increasing percentage on the entire javelin strength training. In order to explore the technique difference between rubber rod throw and javelin throw,quest the rubber rod throw have any effect on the development of javelin throw and special strength .This arcticle has comparaed and analysised one first athlete and two secondary athletes who throwing rubber rod and javelin by means of high speed video,picture analytic and mathematical statistics.The results show that:(1)In the eyes of entirety kinematic parameters and limbs kinematic parameters, the differences of spatial structure about entire movement,force sequence between rubber rod throw and javelin throw are slight in the stages of final thrust.,the practice can better reproduce the characteristics of javelin throw.(2)It is effective to develop the special quick strength of leg,hip and shoulder girdle by rubber rod throw execise, establish the thrust order sense of big link drive small link, to enhance capacity and improve the coordination of specialized technology, but also because of its short and light, and the danger of small, help to organize and implement training to improve teaching, training efficiency.(3)Because of the mold,weight and different length between rubber rod and javelin,the former restrict wrist is relatively low, the putting point of rubber rod is relatively further back as to javelin throw,so easily right elbow throwing objects rubber rod when not fully extended, and finally forced the starting position at a higher equipment problems. The proposed use of the means of athletes in training, a sense of control over the body center of gravity and the spacing between devices in order to lengthen the time throw away from the work equipment.(4)It is clearly that the rubber rod in this study is of less weight and length, So it is suggested that use this measure during the teaching and training can choose heavier and longer instruments.On the one hand,there will be difference between the technology of rubber rod throw and javelin throw,on the other hand,the effection of rubber rod strength training can't be exploited. So it is suggested that use this measure during the teaching and training can choose heavier and longer instruments.(5)The execise of rubber rod can be assisted by different weight device execise, To ensure the balanced development of athletes'special strength ,special speed and special technology.Due to the limitation of conditions,the research has only discussed one kind weight and length of instrument,the differences of the rubber rod throw execise and javelin throw with different weight and length ,together with the vary infection for javelin throw technology and the development of special strength will come under research.
