Three Dimensional Kinematics Analysis On The Last Two Steps Approach Run And Take Off Technique Of Chinese Elite Male High Jumper

Fosbury flop is that 1970's appears one kind new high jump technology. High jump project advantage project having been our country athletics, especially the male person high jump project lays stress on comparatively, our country high jumper Zhu Jianhua once broke the world record 3 times , was that track and field of our country history has written down brilliant piece. So far till, that our country and the Asian male person high jump record still is that Zhu Jianhua breaks and keeps. Our country male person high jump project is counted 10 years across but with a batch of old Young Pioneer's being released from service, when achievement landslide phenomenon has appeared, male person high jump achievement still can not find an improvement , we are necessary carrying out analysis on the cause bringing about achievement coming down studying , find out the factor affecting our country male person high jump achievement's , submit improvement suggestion , provide a theory basis to development of our country male person high jump with the coming of Beijing Olympics in 2008 , as our country track and field advantage project.The technology 3-D kinematics having carried out last two step approach runs and taking off specifically for our country male person high jump achievement current situation, to our country elite male person high jumper studies the main body of a book. In final studying the marriage partner is to participate in the whole nation track and field championship contest SHIJIAZHUANG station male person high jump competition in August, 2006, achievement is an object of study in 2.10m 9 athletes of all above.Analytical main content is that the athlete technology parameter on best result parameter and the maximal altitude failing in time of competition carries out comparative analysis; Simultaneous, pass to consult the relevance document data and books, the relevance data having gained the excellent athlete of world, is that the thesis has carried out additional remarks.The phenomenon with the good and the bad intermingled studying result indicates speed , our country male person high jumper makes approach run of is grave, though the approach run speed existence, but some athletes having technology style difference between the athlete and the athlete insists to hang down excessively. At the same time, our country there exists last two slanting high step speed loss rate phenomenon in athlete , leads to work with useless effect increase by, both the extent affecting regular body centre of gravity ups and downs, and the fault wasting physical power , causing competition to take off in process frequently.And our country athlete is partial to small condition in 1 at every step strong point failing to mount existence upside down highly, between being compared with successful altitude numerical value, first , second existence difference. Return back moreover in studying find that, on the altitude failing, our country athlete takes off moment vertical speed insists to hang down obviously , take off the leg knee , the ankle joint expand insufficiency , take off swing extent and swing speed of stage swing leg are smaller than highly upper successful numerical value equally. The above-mentioned condition specifically for our country male person high jumper appears, has submitted corresponding suggestion.
