Abstract
Chinese women javelin thrower Lv Huihui won the championship of China Long Throw Open in 2013. However, there was still a large gap between her result and the world record. In order to improve her stroking techniques and enrich technological theories, we used advanced three-dimension picture to take up Lv Huihuis spell throw in game site. We also made three-dimension analysis on the last exertion skill and got the kinematics parameter to compare with the foreign elite women javelin thrower. The results show that Lv Huihuis stretch angel is 13.8° smaller than world elite athletes. Her flexibility is not so good that she cant do the full bow action completely. As for the last left knee stretching process, Lv Huihui and other Chinese elite athletes get the results of 5.3°and 10.2 °, while world elite athletes get 16°. It shows that Chinese athletes left knee stretching is not good. Lv Huihuis release speed is 23.36m/s, better than the Chinese athletes average level 21.36m/s, but this speed is much slower than the world elite athletes release speed 24.80m/s. It is the major reason that makes Lv Huihui remain a large gap with the world elite athletes.
