The Kinematics Analysis On Women Jumper's Technology During The Take Off Course In The Tenth National Sports

High jump took an athletics movement project, was apart from already has more than 100 years history now. The female high jump movement development has experienced long and the difficult course. In 1957 our country renowned female high-jumper utilized cuts the type high jump technology to break the world record by 1.77 meters result, has shocked the world sports world. But after henceforth, our country female high jump is at the stationary state continuously, even appeared the phenomenon which backs up, not only has lost the superiority gradually in the world, moreover has also lost the leading status in Asia. Makes this kind of aspect the reason is various, but in the final analysis because athlete's technical backwardness creates. In the high jump technology link, takes off the quality to affect directly to the athlete competes the result display. Therefore, this article through in takes off in the process to our country outstanding female high-jumper to take off the technical related kinematics parameter to carry on qualitatively, the quota research analysis, discusses our country outstanding female high-jumper in to take off the technical kinematics characteristic, found the solution technology backwardness in the research the breakthrough point.This research choice participates in 2005 before the tenth session of national athletic meet female back more -like high jump finals six athletes is the object of study, uses the literature material law, the movie photography law, the image analysis law, the mathematical method of average to the object which studies takes off the technology to carry on the analysis and the analysis. The findings indicated that, our country outstanding female athlete's height, the body weight, the gram request Lai index is lower than the world outstanding contestant obviously, explained also has certain disparity in the bodily shape. Because our country athletes swing the leg lack of strength, must through make in a big way in the approach process curving reduces the bodily center of gravity, thus causes the approach speed to reduce. Front at the same time, as a result of the swinging leg lack of strength, in takes off swings the leg pedal to extend weakens, affects the coax front to deliver, as well as the approach with the smooth engagement which takes off.Must be higher than the world top athlete in the approach stage level speed our country athlete, but is taking off liftoff instant to leap the vertical velocity to be smaller than actually the world top athlete. Although our country athletes have the approach speed quick characteristic, but the approach speed effective use factor (transforms level speed as vertical velocity efficiency) by far is smaller than actually the world top athlete, this with takes off leg fast forcibly ability and takes off the technology to have the close relation. Takes off starts the instantaneous landing angle not to be unstable, creates this kind of phenomenon the reason is because athlete's leg department strength is bad, easy to cause to take off the leg cushion scope oversized, the cause horizontal kinetic energy cannot the very good transformation for take off the leg extensor elastic potential energy. In takes off in the process, similarly as a result of the swinging leg, the upper limb lack of strength, causes not to be able for to take off the process to provide the good upward power, therefore the swinging leg as well as the upper limb lack of strength becomes the athlete to urgently need one of solution questions.Although our country athlete approach level speed is bigger than the world top athlete, but cannot transform smoothly the approach superiority for the center of gravity leaps the vertical velocity the superiority. Therefore, strengthens our country athletes to take off the leg level speed use factor to become in the training an important link. Takes off in the back more -like high jump in the process, swings the leg swinging technology to have the extremely vital role to the high jump result, our country female high-jumper should pay special attention to the enhancement swinging speed during enhancement arc of oscillation the training. Takes off fast in the maintenance under the premise, enhances suspends the arm the arc of oscillation, with takes off the leg full pedal straight degree is enhances our country female high jump movement result the important attribute.The Chinese athletes have own technical characteristic, but with the world top athlete's between disparity also is obvious, still needed the unceasing improvement and the consummation. Because the influence technology factor is various, therefore in the comprehensive solution technical question, simultaneously should unify Chinese athlete's concrete actual situation, is different from person to person the formulation reasonable training plan.
