KINEMATIC ANALYSIS OF ELITE JAVELIN THROWERS

Abstract

Research on various aspects of the throwing motion has indicated it to be a very complex movement (Atwater, 1979). Certain kinematic parameters appear t o be common determinants of successful performance regardless of the nature of the throwing task. Under ideal conditions (i.e., ignoring air resistance and the type of implement being thrown) the path, and hence distance thrown, is determined by the angle, height and velocity of release. Such an ideal analysis needs some modification for situations in which aerodynamics are considered. Since the release phase of the javelin throw encompasses these common throwing components as well as obvious aerodynamic influences, quantification of release characteristics which establish the initial conditions of f light is important.
