Irrational Torque Technique of Hammer Throwers

This study explains that the technique of certain hammer throwers is irrational. Below the citation, you can see a video about the comparatively rational techniques of Soviet hammer throwers.

Kinematical Research on the Whole Pace and the Features of the Kip and Knee of the Throwing Technique of Chinese Elite Female Hammer Throwers,” Zhang Jinyi, Value Engineering, October 2011. The authors, at Xinjiang University of Finance & Economics,Wulumuqi,China, report:

“By using the method of close-range dynamic three-dimensional cinema,the author makes a kinematical analysis on the technique of torque for Chinese elite female hammer throwers.The study shows that the pace of movement and the construction of time of the technique of torque of Chinese female hammer throwers are irrational.”
