Research on the Choice and Control of Angle Parameter while Throwing Shot Put Based on Kinematics and Dynamics

Abstract:

For the shot put movement, in throwing process the factors that affetc the result mainly have shot put action, athletes final exertion, athletes initial speed of throwing, athletes release height and shot-putting angle and so on. And this paper had a research on the choice of angle parameter of release in throwing process that affected the result of throwing shot put in the circumstances of certain initial speed of throwing and release height.The first it had built mathematical modeling of motion trajectory in the process of throwing the shot put, it analyzed the relationship model of the initial speed of throwing, release height and shot-putting angle. Secondly it understood that the scientific change of throwing angle can significantly improve the shot put throwing performance from the relationship model in the circumstances of certain initial speed of throwing and release height. This article was based on the research of angle parameter of throwing the shot put to provide a theoretical basis of the angle parameter of throwing the shot put of domestic shot-putter in peacetime training and competition. And the related data from the game and training of domestic excellent shot-putter was combined with the mathematical model to test and verify the rationality of the mathematical model and provide the scientific guarantee for domestic shot put movement to raise the level of sports.
