摘要

This paper uses the motion aerodynamics principle to analyze the javelin flight process, integrates related factors with athletic performance in the study of the force condition and movement condition of the human body and the javelin, numerically simulates the different angles of fixed parameters by Mathematic software, obtains the theoretical optimum throwing angle 40°, that is when the shot angle is 40° and the angle of the javelin????s long axis with the horizontal surface is 31° the throwing distance reaches the greatest. The results are very consistent with the actual situation; this article canmake reasonable suggestions for the promotion of this project????s athletic performance, provides a theoretical basis for the javelin sports technique, and confirms the reasonableness of existing theory and technique.
