Abstract


Women’s triple jump as a young project, its history is very short, only ten years.In1909, the U.S. athletes Celine create8.805m. Because a long time is not an officialevent of the World Series, the women’s triple jump only in a very few countries tocarry out the technical action is still very rough. IAAF formally established until1990,the first world record of the project.1991, the IAAF for the first time the women’striple jump as the performances of Spain Serbia at the World Indoor Championships,and declared to be included in the1993World Championships in Stuttgart officialevent. In1996, the women’s triple jump to become an official Olympic sport, thisdeveloped rapidly worldwide. According to statistics, so far, there are16passengersexceeded15meters achievements. The current world record score of15.50m theUkrainian athletes Kravitz created. In the next decade or so, the women’s triple jump,both in the highest level of overall level are qualitative development has made greatprogress.This topic using literature data, expert interviews, video capture, imageresolution, and mathematical statistics method, the Chinese elite female triple jumpersin the last two steps, the first jump of the technical features of the analysis, researchand content mainly related to (1) the last two steps of the Chinese elite female athletesin the triple jump step run-up speed comparison analysis;(2) comparative analysis ofthe Chinese elite female athletes in the triple jump take-off stage, which involves onefoot jump part of the speed parameter kinematic analysis, take-off and take-off leg ofthe angle from the angle analysis, one foot jumping, the angle between the two legs ofthe ground an instant analysis, joint angle of take-off leg flight angle;(3kinematicanalysis) triple jump last two steps, first jumping the height of the center of gravity ofthe elite female athletesFinally the run-up two steps, the first jump of the technical features of thetraining recommendations:(1) From the triple jump final run-up to the step and pace,our athletes should strengthen the ability of the absolute speed after a few steps in therun-up to take full advantage of run-up the horizontal acceleration, and strive for the"run and jump" feature, as well as the last few steps stride stability training;(2) Afterthe two-step with one foot jump run-up to the amount of cash should be noted thattake-off leg, take off the angle between the requirements of different angles, tostrengthen the smooth undulating body weight, to minimize the loss of the horizontal velocity.(3) The Chinese elite female triple jumpers should be noted that the angleproblem take off swing Tuixi the angle, to strengthen our core area of the women’striple jump athletes training, people become compact some.(4) Overall, specifictechnical training triple jumper, in conjunction with the actual situation of the athletes,embodies the principle of "personalized" training, the athletes play to its advantage ofas much as possible on the basis of their own advantages
