The purpose of this study was to present effects of the immediate feedback training on techniques in college male javelin throwers. The participants were five college male javelin throwers. The technical problems revealed by the preliminary motion analysis were explained to the participants for this experiment. In the immediate feedback training, an iPad displaying the motion pattern of the ELITE throwers (Notomo et al., 1998) was set up, and a delayed playback device was used to allow the participants to visually compare their own movements with the model after throwing. Three trials were performed in each of before and after the training sessions. The best recorded trials in each of the training sessions were selected for analysis. Three of five throwers improved their deceleration of center of gravity and trunk rotation, although improvement in the record and the release speed of all participants was not observed.
