JIMENEZ-SALAS, J et al. Polar coordinate analysis for the study of defensive systems in Handball. CPD [online]. 2020, vol.20, n.1, pp.103-117. Epub 29-Jun-2020. ISSN 1989-5879.
The objective of this study was to analyze the relationship of different offensive tactical performances with the behaviours shown in the two main defensive systems in handball. For this, an analysis of polar coordinates was carried out using as focal behaviors those wich identify the main defensive systems and the offensive actions with or without transformations. There were 538 situations corresponding to 5 matches of the first Spanish national men's division with the Hoisan software by making use of an ad hoc tool. The observational design used was nomothetic, punctual and monitoring, the observation unit being the defense situation of the monitored team. The results of the Data Quality and Generalizability analysis show convincing rates for the models used. The results of the Polar Coordinates analysis show the greater oppositional capacity of the 5: 1 defensive system to attack. It also highlights that the attacking transformation from 3:3 to 2:4 is used more in the face of open defenses and it elicits an increase in the appearances of disciplinary sanctions. The observational tool designed and the use of the polar coordinate technique for the estimation of tactical relationships allows to define intervention procedures that optimize the resources of training and competition in handball.
