内容記述 | The purposes of this paper were to compare kinematic data between a top national athlete and an university athlete, and to resolve the hammerhead acceleration into five components : acceleration of the center of mass of the thrower, coriolis acceleration, centripetal acceleration, tangential and radial acceleration of the hammerhead. The throw was governed mainly by the release velocity of the hammerhead. As the distance between the centers of mass of the thrower and hammer-thrower system of the university athlete was shorter than that of a top national athlete, the center of mass of the university athlete viewed from overhead moved in the direction of the linear trajectory of the center of mass of the hammer-thrower system, while the hammerhead moved from the low-point of its path to the high-point. In general, the thrower retained his balance against the centrifugal force of the hammerhead, and moved and rotated on the throwing circle. The coriolis and tangential components acting at right angles to the vertical plane, which includes the center of mass of the thrower and the hammerhead, were large. The centripetal component acting along the wire length in the vertical plane was also large. The thrower exerted a centripetal force on the hammerhead during the low-point of its path in all turns. The distance between the center of mass of the thrower and the hammerhead decreased in his late turns, and then the angular velocity increased ; consequently, the linear velocity increased. | |||||
