The present study was investigated the strategy of modern football. And we analyzed of the offensive system during 8 games in the World Cup Italy 1990. Average goals per game was 2.19 (in 52 games and 114 goals). The number of stealing the ball per 1 game were, in a team won a game, 116. 8 times/game and 114. 1 times/game in a team lost a game. The most number of stealing the ball in the field was 549 times in Area B (defending nalf). In a team won, numbers of stealing the ball in Area D and E was more than that of a team lost a game. With regard to a style of stealing the ball, a team won a game had lots of direct free kicks and pass intercepts etc. , but a team lost a game had lots of goal kick and saved a ball by goal-keeper. With pressing a highly developed tactic, success often depended on a team's ability to cop e with crowded areas and intense pressure. One significant factor in this situation was the speed with which a team reacted to a lose or gain of possession. Stealing the ball, counter attacking at space, taking quick free kicks, and surprising the oppositi on with either fast or disguised moved were all important methods of overcoming compact, highly organized team units.

    In this study, as well as Oe (2007) using the configured evaluation team tactics, patterns were analyzed to quantify aspects of an effective attack to break through in international soccer game, the following conclusions were obtained.
    1. Constitute a confirmatory factor analysis model for all aspects of the attacks against representatives of the two games against Slovakia and Japan Representative for Japan national team against UAE representative, population analysis revealed that simultaneous multi-factor loadings between the factors of the path and showed a high degree of fit of the model placed constraints imposed on the covariance, etc., has been verified that the factorial invariance is established. This showed that irrespective of the population to match the 10 factors extracted.
    2. Simultaneous multi-population analysis, using factor scores derived from the model were adopted, cluster analysis classified the attack scene. As a result, six pattern making stage, 11 stage trick patterns were classified into four phases break the pattern. The magnitude of the effect of the factor scores in attack patterns that characterize each phase (ES) and the success rate, could be an effective hierarchy break aspects of the attack pattern.
    3. By quantifying the attack scene, can be regarded fragmented attack patterns, it was clear to verify its effectiveness. Quantitative evaluation of the breakthrough stage attack patterns obtained in this study is superior in terms of objectivity, because when objective information and coaching tactics, thought to contribute to capacity building of soccer stadium be.

The present study was verify of reliability and validity the regression equation constructed using the game footage from the 2010 FIFA World Cup. Formulated using multivariate logistic regression analysis, this equation’s purpose was to predict the probability of a goalkeeper’s failure to stop shots at goal. The 2014 dataset consisted of 587 shots at goal from within the frames during 64 games played by 32 teams that participated in the FIFA World Cup in Brazil. The results showed that for the probability of failing to block a shot predicted by the regression equation, the 2 inter-rater interclass correlation coefficient was high (0.91), thus demonstrating reliability. Furthermore, when a contingency table was created with a cut-off value of 0.5, accuracy was high (85.9%); when an ROC curve was drawn and the area below the curve was measured (0.874), it was notably distinct, indicating generalizability. Therefore, the regression equation predicting the probability of failure to block a shot has high generalizability for predicting world-class goalkeepers’ probability of failure to block shots. This is considered a useful formula for evaluating goalkeepers’ blocking ability.

 In recent years, interests on the tactics learning of ball games have been rising in the field of school physical education in Japan.

 The purpose of this study is to examine an assessment standard of game performance based on viewpoints of the tactics learning in soccer. Thereupon, the assessment of games of soccer in physical education in elementary school was intended. As the assessment standard of the game, Allen Wade’s Principle of Team Play （1967）, which affected TGFU (Teaching Games For Understanding) and TSCS (Teaching Sport Conceptsand Skill —A Tactical Games Approach—), was applied.

 As a result, followings have been made clear.

1. Games of children made progress along the route of genealogical evolution of soccer.

2. The games of children made progress gradually to the 1st phase (Penetration), the 2^nd phase (Depth), and the 3^rd phase (Width). Then, it can be estimated that it develops to the 4^th phase (Mobility) and the 5^th phase (Improvisation).

3. The progress stages of the game of children matched the principle and priority order of the team play.

 Therefore, the Allen Wade’s Principle of Team Play can be an assessment standard of the game performance based on viewpoints of the tactics learning in soccer.

    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)
