In shot training and competition process, shot throwing distance is a problem of crucial importance. This paper analyzes shot movement process as well as shot movement data by Newton Kinematics and blockage growth model. According to shot movement process different statuses, divide it into hand push process and air flight process the two stages. Control throwing speed enough large, it needs to improve accelerate speed in accelerated process; When throwing shot, ball throwing direction and horizontal direction included angle should keep around 45 degree. Through statistics Olympic Games shot performance data from 1896 to 2004, use Matlab draw out performance general direction, get conclusions that Olympic Games shot event performance growth situation has an analogy of blockage growth model, therefore adopt blockage model to predict Olympic Games shot event performance. Through searching 5 years’ summer Olympic Games champions performance from 1952 to 1968, make prediction of previous Olympic Games shot performance, and true value get more close to predict value with smaller errors. Finally, this paper proposes relative reasonable suggestions on how to let shot putter gets good results in competition by establishing above model.
