AB The aim of this study was to determine the effects of changing the distance of the penalty shot in water polofrom 4 to 5 m. While a shorter distance made the penalty shot more effective, it also reduced the use of this sanction. Atotal of 192 matches played in the 2003 and 2007 Water Polo World Championships were recorded. The sampleincluded 278 penalty shots in both tournaments. Notational analysis using a longitudinal correlational and descriptivedesign was employed to determine whether a longer distance increased the number of sanctioned penalties (81 vs 197)and caused a non-significant decrease in scoring efficiency (7.4%) with significant differences in the relationshipbetween the area and the type of a shot, with less centre and power shots (14.8% vs 7.1%) observed and predominanceof bounce shots to the right of the goal posts. The rule change prompted more penalties, produced changes in shotdirection as well as the type of a shot, and yielded a decrement of 7.4% in scoring efficiency.
