Influencia del tipo defensa sobre el éxito en el lanzamiento/Influence of defense system on basketball shooting success/Influência o tipo de defesa sobre o sucesso no lançamento

The aim of this study was to identify the relationship between defensive team systems and effectiveness in basketball. A quasi-experimental study based on a case study in a natural context using observational methodology was performed. A validated instrument called SODB registered 402 field goals. It can be highlighted next findings: a) no significant differences between defensive team systems and the success or failure of field shots; b) the highest number of field shots were made against positional systems; c) the individual system presented the highest number of field shots; d) the best success rates in the field shots were obtained when confronted with situations of defensive transition. With the data shown in this study we can consider, for the future, other studies about predictors of success in field shots. In addition, coaches should inquire about relevant strategies to shoot in situations which defensive team is disorganized because they are more chances of success.
