<p> The Aim of this study was to clarify the saving motion which soccer goalkeepers (GKs) have to acquire preferentially by analyzing the performances of GKs during games. Data were obtained from 27 official games such as 2014 Kanto University League and others. 54 GKs were sampled for analysis. 1398 performances of GKs were recorded on videos. We categorized 303 saving motions into seven motion patterns: diving motion with preparatory motion, diving motion after side step with preparatory motion, and so on. And we classified 1095 motions except the saving motion into seven items such as goal kick, throwing after the ball catching and so on, and counted up these items. The novel findings were as follows: (1) the most counted GK-specific motion is the saving motion. Especially, the diving motion with preparatory motion is most counted. (2) In most cases, GKs jump lightly as the preparatory motion before saving motions. (3) According to results from the shot area and the shot height, it is clear that GKs corresponded to the shot kicked from the inside of the penalty area to various heights. (4) It is assumed that it is necessary for GKs to acquire the diving motion with preparatory motion to correspond to the shot kicked from the inside of the penalty area to various heights. In addition, it is thought that the findings in our study are useful for biomechanical analysis of diving motion of GKs. (237 words)</p>
