Abstract
  • The purpose of this study was to determine the effects of the technical parameters: throwing phase time, hip-shoulder and shoulder-arm separation, trunk tilt, and throwing-arm elevation on discus throwing performance. Videographic data of male and female discus throwers' competitive performances were captured during major meets. Real-life, three-dimensional coordinates of 21 body landmarks and the discus were obtained for 283 trials using direct linear transformation. The technical parameters were reduced at six critical instants during the throwing procedure. Canonical correlation and hierarchical stepwise multiple regression analyses were performed to determine the relative influence of linear combinations of the technical parameters on release characteristics and performance. Specific techniques associated with linear combinations of certain technical parameters were identified for males and females separately. Vertical release velocity was identified as the principal determinant of the difference in performance between athletes. Suggestions for increasing vertical release velocity using effective and efficient technique were made.
