Abstract


The aim of this study was to investigate the characteristics of players according to their experience levels during Flying disc forehand throwing. Two players were recruited for this study according to their experience level (skilled (SP) and unskilled (UP)). 3 dimensional motion analysis were performed to analyse the disc trajectory and inter-joint coordination patterns qualitatively. SP showed greater range of disc trajectory both on horizontal and sagittal plane according to their release point. Coordination patterns showed differences especially on shoulder and wrist joint angles. Disc trajectories and inter joint coordination results can be explained as a result of changes on upper body moments according to the experience level of players. Therefore, these characteristics increase the initial velocity of disc which can affect the disc.
