Indicadores de performance de equipes vencedoras e perdedoras em jogos equilibrados do Campeonato Brasileiro de Rugby Sevens feminino 2018

Abstract

The aim of this study is to compare technical performance indicators of winning and losing fixed teams in balanced games (up to 16 points difference) of the 2018 Brazilian Women's Rugby Sevens Championship. A retrospective observational analysis was conducted, where 2 experienced evaluators analyzed 134 variables related to technical aspects in the Long Match Version 0.18.10 software, using video recordings of 56 games. For statistical treatment of data, the SPSS statistical package was used and the alpha adopted was p = 0.05. The Shapiro Wilk test was used to verify the normality of the sample. Since the database does not have a normal distribution, the Mann Whitney non-parametric U test was subsequently used. Variables that presented a significant p-value and together presented a median value of zero had the results grouped and were submitted to Pearson's Chi-square test. The results show that the variables related to the winning teams are: right tackles in offense with 1 player involved (p = 0.012), right tackles in offense with 2 players involved (p = 0.020), kicks in defense out (p = 0.001), wrong passes made in offense (p = 0.018), offense recovery via live ball (p = 0.003), total ball recoveries (p = 0.002), defensive line-out with 3 players won (p = 0.027), try with 1 phase and originated from a scrum at 22m of defense (p = 0.042), try with 1 phase and originated from a scrum at 22m of attack (p = 0.006), try with 1 phase from recovery at 22m of attack (p = 0.029), 2-phase try from midfield recovery (p = 0.042), 3 or + phase from 22m recovery (p = 0.042), 3 or + phase from 1 free kick in midfield (p = 0.047), total tries (p≤0.001). The variables related to the losing teams are: wrong tackles made in defense with 1 player involved (p = 0.017), rucks with outcome pass made in defense (p = 0.018), ruck in defense with outcome drive (p = 0.057). Therefore, women's Rugby Sevens teams use high physical and technical skills to achieve victory and become successful in competitions. Training programs should include maintenance of allpossession (fewer technical errors such as wrong passes, possession errors, maintenance of ruck and scrum possession, high level of ball retention in line-out disputes), tackle effectiveness with 1 and 2 players, game plans to exploit the tactical fragility of the opposing team, from the defensive field towards the attacking field, because these actions of the game are shown as determining factors for the success in women's Rugby Sevens matches.
