Abstract: In this paper, the impact of the pushing force on the release angle of the shot-put sportsman is studied, and the optimal value of the release angle is calculated numerically using the MATLAB. Some influencing factors on the optimal release angle, such as the height, pushing force, attenuation coefficient of angle and shot's mass are discussed.

Key words:

shot, optimum release angle, extinguishing coefficient of angle
