The aim of this study was to compare the shot success rate with number of attempted shots according to attack patterns, as obtained during the preliminary and eighth final rounds of the 2012 National Water Polo Elementary School Championship tournament. There were 790 shots in the preliminary round and 260 during the eighth final rounds that were analyzed statistically by the chi-square test.
1) Shot success rate was seen to improve in counter attacks (64.9%), power plays (42.3%), and center shots (36.7%). The success rate of action shots and middle shots deteriorated.
2) The ratio of the number of successful skip shots to total number in the eighth final was significantly higher than in the preliminary round (p<0.05). The ratio of skip shots to the total number of goals was 34.9% in the eighth final, and 10.7% in the preliminary rounds.
3) Analysis of the total number of successful goals showed that 74.1% (eighth final) and 63.2% (preliminary) of these were scored inside the 5m line, indicating attempts closer to the goal resulted in a higher shot success rate.
4) Of the total number of shots, 60% were immediate throws and 40% were fake-throws. For both types of throws (immed
