I am going to attempt a summary of an article published in Sports Biomechanics called “Biomechanical analysis of the sidearm throwing motion for distance of a flying disc: a comparison of skilled and unskilled players.” I am hoping to offer something brief, easily understood, and practical. If you want experimental details, or are looking for something more erudite, please read the paper : )
In this study ten skilled and seven unskilled players were taped throwing forehands as far as they could. The movements of their shoulders, arms, and wrist were analyzed. The initial velocity of the discs, spin rate of the discs, all angles of the disc, and distance of the throws were measured.
