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

对两名链球运动员在掷链球转体过程中，采用轻、重量级链球，对链球的张力和投掷动作进行研究。结果表明，在链球转体过程中，常规重量的10%或以上，速度训练以6.5~7.26 kg的链球为宜。作用在锤头上的离心力最大的重量分别为7.6公斤和7.9公斤，体重大于100公斤的运动员离心力几乎没有减少。因此，在把重量级链球作为力量训练时，使用7.6公斤至7.9公斤重的链球是必要的，认为有必要根据体重改变链球的重量。

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.
