The Analysis Of Swing In The First Hop Of Excellent Women’s Triple Jump Athletes In China

In this paper, with the top six athletes who participated in the2012NationalIndoor Championships (Nanjing Station) for the Women’s Triple Jump as the targets,the comparative analysis on taking-off effect was made with the main method ofkinematic test, together with the literature, expert research, fixed-point shooting andresolution, mathematical statistics and other research methods, on the instantaneoushorizontal velocity before taking off, into-jumping angle, swinging leg hip angle andtaking-off angle in the first jump of athletes; relative analysis on kinematicscharacteristics and swing effect was made on the biggest lowering knee angle ofswinging leg and corresponding taking-off leg phase front-swing hip angle, kneeangle, upper limb swing characteristics by different swing techniques forms inkinematic conditions for producing force for jumping again. Through analysis andresearch, we believe that:Through the analysis of the first jump jump before the instantaneous horizontalvelocity and the jump Angle, swinging leg hip Angle and take-off Angle it can provethat: the kinematics parameter on jump effect, Ms Xie limei, is the best in the Chineseexcellent woman’s triple jump athletes, and the take-off technology structure isbasically right and effective.In the research object, in addition to the Ms Xie limei of the swinging leg outsideradius is bigger (close to man swinging technology), several other players swingradius are inadequate, there will be "the swing" into a "leg" negative technologyconcept. In the subconscious phenomenon, reduce the oscillation amplitude, shortenthe swing radius will likely weaken the side legs "wobble" for quick jump take-off legsupporting mechanical effects.During the first jump leg swing technology exchange, swinging leg swing radiuswith the change of knee joint Angle change trend, present positive correlationinteractions, swing radius is small, the knee joint Angle is small, on the contrary, theknee joint Angle is swinging radius will increase; And swing radius increases, relativeto one another will make the swinging leg and take-off leg work distance islengthened, thus to provide rapid take-off power good mechanical condition.Triple jump arm swing amplitude or swing radius size or length, form and effectof swing leg with highly unified, swing athletes put legs big radius, either in the formof arms swinging, the extension of the swinging leg ipsilateral arm or radius, aresignificantly greater than athletes use knees shrinkage type oscillation, due to theincrease in body turning radius in the air, will also indicates they have a better balancein the air condition, and the ensuing second jump takeoff, we intensified the efforts on swing space and, built more fully kinematics condition.Recommendations: to strengthen the profound understanding of the technologyfunctions of swing legs, may improve the technical level of training in the Chinesewomen’striple jump, play a positive role in promoting; it is suggested to help athletesovercome thepsychological fear in the implementation of putting down leg with largeradius, to further improve the actual effect of swing technology.
