| 内容記述 | The purpose of this study was investigate that the influence of the body weight on the pulling force during throwing motion in hammer throw. Throwing motions of 2 elite hammer throwers were recorded by 2 synchronized high-speed video cameras (200 fps) in two international athletic meets. Three-dimensional co-ordinates of body segments and hammer head were obtained with DLT techniques (Abdel-Azis and Karara, 1971). Initial conditions at release and maximum pulling force acting of hammer head during throwing motion were calculated. Throwing distance and initial conditions were similar in two throwers. However, maximum pulling forces per body weight were quite different. The hammer throwing motion can be compared to two-body problem in the physics between a thrower's body and hammer head. Therefore, it can be considered that body and hammer head rotate each other around the common center of mass of these two bodies. This study identified the influence of body weight on pulling force during the hammer throwing motion. It was concluded that the thrower with smaller body weight had a disadvantage, from the mechanical viewpoint as well as muscle volume. | |||||||||||
