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.

本研究旨在探讨两名链球运动员在链球投掷转身过程中，使用轻、重链球时的链球张力及投掷动作，结果表明，链球投掷转身过程中，链球张力已达到常规重量的10%以上，速度训练应使用6.5 ~ 7.26kg重的链球。作用在锤头上的离心力最大的重量为7.6kg和7.9kg，体重大于100 kg的运动员离心力几乎没有减少。因此，当将重锤视为力量训练时，使用7.6kg至7.9kg重量的锤，并且认为有必要根据体重改变所选择的锤的重量。
