摘要：Shot putting is an important component of track and field events and the throwing distance (s, m) is the greatest concern of coaches and athletes. There are mainly three major factors affecting throwing distance: the initial velocity (v, m/s), release angle (A, �) and release height (h, m) in shot push. So far, it is common to use the physical kinematics knowledge in the research of shot putting, but the release height�s impact on the throwing distance is rarely considered. By mathematical modeling and computer simulation, this article analyzes the relation between the three factors (v, A, h) with the throwing distance (s) and determine the best release angle with regard to different release velocity. In addition, the impact of release velocity and release angle on throwing scores is discussed. This article is of certain theoretical guiding significance for athletes and coaches in the selection, training and competition for athletes.
