Análise das cobranças de escanteios no campeonato brasileiro de futebol

Abstract

The objective of the present study was to analyze the corner kicks performed in the Brazilian Football Championship games. Were analyzed 1450 corner kicks from 148 games of the Championship edition held in 2020, with all sampled games taken from the broadcast coverage of closed television channels. The observation instrument used was adapted from different studies that investigated corner kicks in international competitions. Data were analyzed descriptively, from absolute (N) and relative (%) values and through cluster analysis using the maximum distance method between grouping values, based on the gower method for mixed variables. Furthermore, a bivariate analysis was performed with contingency tables using a chisquare test for categorical variables, with the criterion variable being the result of the corner kick (Goal x no Goal). The results revealed that there were, on average, 9.81 corners per match, with the majority of the corner kicks being sent in the penalty area, performed between the 60th and 75th minutes of the game, and executed with a high trajectory and with the outside arc of the ball, with the finalization performed mainly with the head. In turn, only 32 (2.58%) resulted in a goal. The inferential analysis revealed that the final contact surface was related to the result of the corner kick. It is concluded that the corner kicks performed in the Brazilian soccer championship have characteristics similar to those found in other countries.
