Quantitative analysis of athlete technical feature affecting shot performance based on matlab simulation

Bing Ge1, Yan Gao

By establishing shot throwing mathematical model, regard shot as a particle, ignoring air resistance. In case it researches landing point and throwing point in the same horizontal line, use Newton mechanics and relative physical knowledge making force analysis of shot,only suffers gravity G, it is clear that it makes constant movement in horizontal direction and makes constant decelerated movement in vertical direction, and so it can get L and v, α relationships. And it researches landing point and throwing point are not in the same horizontal line status according to practice, finally it gets L and v, α as well as h quantitative correlations, and according to searched data, use quantitative analysis method, through Matlab programming, it gets correlation simulation figure, respectively gets corresponding best release speed, release angle and release height.
