KINEMATICS AND AERODYNAMICS PARAMETERS ON PARALYMPIC DISCUS THROW
The purpose of this present study was the kinematics and aerodynamic evaluation of a disabled discus throw. The sample was carried out by thirty one throws made by an athlete who was for three times Paralympics champion. For the kinematical analysis were used the 3D and 2D kinemetry method. The images were recorded by two high-speed cameras (120Hz) and a low speed one (60Hz). Aerodynamic analysis was calculated by drag and lift forces during flight phase. The results showed good correlations of drag and lift forces with flight distance, and no relation to wind and position to the range. Overall, it was concluded that the drag free equation applied to disabled discus throw can not predict the flight distance. The aerodynamic factors are significant to disabled athletes and require further researches.
