Abstract


The purpose of this study was to gain knowledge about technical requirement in male discus throwers, specific to their performance level, by comparing the parameters of body translation. The performances of 22 male discus throwers were analyzed. The subjects were divided into the following three groups based on the distance thrown: advanced, medium, and novice. From the results of this study, it can be concluded that the relevant technical requirement for novice is a dynamic shifting of the center of gravity to the left during the first double support phase. Furthermore, pushing into the ground vigorously before push-off the left foot to drive the body toward the throwing direction during the flight phase would enable novice group to create greater momentum and achieve a higher performance level.
