Research on the training method of the throwing event which paid its attention to individual physical strength and technical characteristics

本研究的目的是研究两链球运动员用轻锤和重锤在链球转圈时的链球张力和投掷动作。因此，在链球转身时看到的是正常重量的10%或更多，重量为6.5公斤至7.26公斤的链球应该用于速度训练。作用于双髻鲨的离心力最大的重量分别为7.6kg和7.9 kg，体重大于100 kg的球员离心力几乎没有减少。因此，在将重锤作为力量训练时，使用7.6 ~ 7.9公斤重量的锤，认为有必要根据体重改变所选锤的重量。

The purpose of this research was investigate tension of hammer and throwing motion using a light weight and a heavy weight hammer during hammer-throw turn for two hammer thrower.As a result 10% or more of regular weight having been seen during hammer-throw turn, the hammer 6.5kg to 7.26 kg in weight should be used for speed training. The weight from which the centrifugal force which acts on a hammerhead became the maximum was 7.6kg and 7.9 kg, and the player with the body weight of greater than 100 kg had little reduction of centrifugal force. Therefore it is using a 7.6kg to 7.9kg weight of hammer, when treating the heavy weight hammer as power training and it is thought that there is the necessity of changing the weight of the hammer chosen with body weight.
