Résumé:
This article offers a study on the evolution of Brazilian basketball, using Statistical Performance Indexes (IED) as a metric to evaluate team performance in the context of the three most recent seasons of Novo Basquete Brasil (NBB), which cover the period from 2021 to 2023. The central objective of this research is to explore and analyze the performance of the most prominent teams in the Brazilian basketball scene. The data used in this analysis were collected from the National Basketball League (LNB) platform, the entity responsible for organizing and managing the NBB. 883 games were analyzed over these three seasons, covering various statistical indices, which include the average and standard deviation of various parameters, such as scoring, shots (attempted and converted), use of two-point shots, three-point shots and free throws , assists, rebounds, steals, errors, blocks (blocks), efficiency and other advanced metrics associated with the sport of basketball. Data were compared using analysis of variance (ANOVA) and reference values were calculated from percentiles, allowing comparative analysis and identification of trends. In this context, the 2022 season emerged as the one that recorded the lowest rates, especially in terms of shot usage, efficiency, average points and assists. On the other hand, the other two seasons analyzed presented similar numbers in most of the indices studied, which may suggest a certain stability in these aspects throughout this period. Another point observed in the study is that teams competing in the NBB need to reach a high level of performance, as evidenced by the percentiles used as a reference. Furthermore, the study reveals a clear trend towards increased use of three-point shots in recent years of the NBB, in line with the changes observed in basketball at a global level, where the three-point shot has become a fundamental element in strategies. offensive
