| 内容記述 | In water polo games, a team’s offensive ability with the extra-man after an exclusion foul can make the difference between victory and defeat. In the 42 games played by the 12 men’s teams at the 2016 Olympic Games, there were 812 exclusion fouls of which 310 led to a goal. The purpose of this study was to clarify the characteristics of extra-man offense in water polo. Data were obtained and analyzed from the 605 instances in which the extra-man formation used a 4-2 system leading up to a shot. Videos of the games were watched and principal component analysis was carried out on various data. Two principal components were extracted: breaking up the defensive formation and shooting motion. Then, a cluster analysis using these scores was carried out, and characteristics of the extra-man offense were classified into four clusters: CL1: One-motion shots after a parallel pass CL2: Shots after breaking up the defensive formation CL3: Various shots from the top position CL4: Shots with faking motion from the side position No team used CL1 with great frequency because it tends not to be a high-success shooting technique. The success rate with CL2 was high because the offensive team had found an opening in the defensive formation. The teams using this method most often were AUS, USA, CRO, ESP and SRB. CL3 tended to appear when a certain player had a particular shooting technique from the top position or when the team needed to shoot because the excluded player was about to return. Teams using this strategy frequently included AUS, JPN, FRA and HUN. Finally, CL4 was a common technique for MNE, FRA and SRB. The principal component analysis was effective in distinguishing the characteristic strategies of each team’s extra-man offense. |
