| Abstract | ||
| The purpose of research is to design a model for evaluating the skilled performance of throwing the javelin in track and field competitions by means of identifying some biomechanical variables most correlated to the record level of the skill under study and setting the mechanical profile in light of these variables. Three participants who were javelin throwers (elite level) in AlGeyad and Al-Olympic Clubs were selected purposively to serve as a sample. All subjects administered descriptive survey and kinamatogeraphical analysis. Findings suggest a strong correlation between biomechanical variables (horizontal, vertical and resultant velocities, horizontal, vertical and resultant forces of the center of gravity of the body and of the joints -upper arm, forearm, thigh, leg- as well as well as angle and velocity of delivery of the javelin and height of delivery point of javelin) and the record level of throwing the javelin among athletes at elite levels. The paper recommended using an evaluation card for javelin thrower, according to biomechanical variables, in the development and modification of training process | ||
