| Outline of Final Research Achievements |
A flight distance and path of the sports projectiles are determined by the aerodynamic forces acting during its flight. Obviously, its initial conditions are determined by the athlete's skill. Therefore, our research objectives were both the estimation of the aerodynamic forces and the optimum athlete's skill for the sports projectiles. We developed a real time monitoring system for the ski jump trajectory using the infrared red laser scanner. Then, we have established the methodology for the aerodynamic forces on the skier. For the baseball pitching, we could elucidate the theory of the knuckle ball throwing skill of the baseball pitcher. For the discus throwing, we established a computer simulation method for the initial conditions of the optimum flight trajectories.
