This study focused on mini games in soccer, a game generally used as teaching material in PE classes, and examined the effect of differences in the size of the court and the number of the players on load characteristics from the viewpoint of improvement in physical fitness. Twenty male junior high school students participated in the present study. They played four types of games with changing the size of the court and the number of the players: Game A (court size: 30m × 20m, 5 players per team, court area per player: 120m2); Game B (court size: 45m × 30m, 5 players per team, court area per player: 270m2); Game C (court size: 45m × 30m, 10 players per team, court area per player: 135m2); Game D (court size: 60m × 40m, 10 players per team, court area per player: 240m2). The number of ball contacts, the ratio of appearance time of each movement speed and the total movement distance during the game were measured. Questionnaires about the game were conducted after all games. Skill test (pass and dribble tests) and Physical fitness test (50m sprint and 20m shuttle run) were also performed. In analysis of data, eight students among twenty were used. The main results were as follows: 1) The number of ball contacts was greater in small-group games A and B than in large-group games C and D. Among them, there were significant differences in Game A and both Games C and D. 2) The ratio of the appearance time of each movement speed showed no significant difference among the four games at any speed. However, moderate speeds (3-4m / sec) tended to be greater in Game B, in which the number of the players was smaller and the court area was larger (p =0.08), and higher speeds (4-5m and 5-6m / sec) tended to be greater in Games B and D, in which the court area per player was larger. 3) Questionnaire scores were greater in the psychology component (4.0 to 5.0 points) and techniques component (coordination) (4.0 to 4.8 points) than in the physical fitness component (2.9 to 4.1 points), however, no significant difference was revealed among the four games in any questions on any aspect. In the psychology component question which asked about interest, small-group games A and B tended to reveal greater interest than large-group games C and D (p =0.08). 4) In Games A and C, in which the court area per player was smaller, there was a significantly positive correlation between the number of ball contacts and the results of the pass test, while there was a significantly negative correlation between the number of ball contacts and the results of the dribble test. 5) In Games C and D, in which the number of the players was larger, there was a significantly positive correlation between the total movement distance and the results of 20m shuttle run in the physical fitness test. The results suggest that small-group games might improve technique (coordination) in addition to evoking students' volition for learning, and that games in which the court area per player is larger might be available for improvement in their anaerobic power. Additionally, the results suggest that for games in which the court area per player is smaller, differences in basic techniques might affect the number of ball contacts during a game, while for games in which the number of players is larger, differences in aerobic capacity might affect the total movement distance during a game.
