The Three-dimensional Kinematic Analysis On Some Of Our Country Outstanding Female Triple-Jumps Athletes’ Technique Jumps

Analyzing and diagnosing the technique of the triple-jump has the important significance for improving the overall level of the triple-jump of our courntry. This article carries on the scientific research on the female triple-jump by designating first six athletes of the 2013 national track and field championships and national games qualifier, using two Mega speed MS50 K high speed cameras of Canada to synchronizationally photograph by the speed of 100f/s, using SIMI-motion video recording analysis system to analyze picture.The results as follows:(1) Compared with the excellent women’s triple jump athletes in the world, 6 outstanding women’s triple jump athletes of this study, there exists a certain gap on the body shape index, there isn’t obvious difference among the average height,but the weight light and Quetelet index too small.(2) The horizontal speed of the center gravity of body and vertical speed of the 6 athletes was less than the world’s top athletes in 3 jumps.(3) The average angle of touchdown of take-off leg of former 2 jumps is universally lower than the world’s top athletes. The average angle of take-off of hop is universally lower than the world’s top athletes and the third jump is higher than the world’s top athletes. Research objects the jump angle of promoting of gravity of body is smaller, the third jump is higher than the world’s top athletes.(4) The 6 athletes during the the single hop and step of the take-off leg touchdown moment, maxium fore-support moment, stretchup moment of the knee angle are smaller than the world’s top athletes.(5) Compared with foreign outstanding women althletes, the angle of two legs is higher in the instant of the take-off leg touchdown. But the 6 athletes is smaller when in the instant of stretchup than foreign outstanding women.(6) Compared with foreign outstanding women althletes, the 6 athletes’ ratio of 3 jumps, the radio of the the single hop and step jump being still small, the ratio of the third jump is similar.
