The shot is the game action in which the rest of the players' actions culminate, allowing them to achieve thegoal of the game, to score. In this action several factors intervene which condition its execution. The goal of this study wasto analyze the shot, by executing a multifactorial study of the differences in this technical action between two competitionlevels, professional teams (experts) and amateur teams (inexperienced players). The shots taken during 60 games from twocompetition levels, the ACB league (30 games) and the EBA league (30 games) were studied. A total of 10212 shots werestudied, of which 5161 corresponded to the ACB league (174±13.23) and 5051 corresponded to the EBA league(168±19.54). After an exploratory analysis, an inferential non-parametric analysis to assess whether the two samples ofshots were equivalent was used (Mann-Whitney U).Differences in free-throws between professional and amateur teams were only found in the distribution of the shotsby quarter (U=7.5E+005, p=.025). The field goals taken in the two competitions are different with regard to the defensivepressure that the players receive before shooting (U=6.4E+006 p=.025), the shot value (U=7.1E+006, p=.010), and theaction taken before the shot (U=6.6E+006, p=.000). The expert players (professionals) have a greater command of thegame than the amateurs (inexperienced players), they maintain a higher defensive intensity from the beginning of the game,they are able to find shot positions in which the defensive pressure is less, they use more collective actions to look forbetter shot positions (passes), and they can shoot from greater distances.
