Department of Physical Education, Ocean University of China, Qingdao, Shandong, China
Based on the movement process of throwing and in order to further improve the throwing technique of our country, this paper will first illustrate the main influence factors which will affect the shot distance via the mutual combination of movement equation and geometrical analysis. And then, it will give the equation of the acting force that the throwing athletes have to bear during throwing movement; and will reach the speed relationship between each arthrosis during throwing and batting based on the kinetic analysis of the throwing athletes’ arms while throwing. This paper will obtain the momentum relationship of the athletes’ each arthrosis by means of rotational inertia analysis; and then establish a restricted particle dynamics equation from the Lagrange equation. The obtained result shows that the momentum of throwing depends on the momentum of the athletes’ wrist joints while batting.
Key words: analysis of throwing technique / mechanical analysis / biodynamic analysis / rotational inertia and tensor
