Análise do Atlético-MG na Arena MRV: mudanças no desempenho e fatores associados

Abstract

This study analyzed variations in the sports performance and technical-tactical metrics of Clube Atlético Mineiro before and during the transition to Arena MRV as its exclusive home venue. Using a retrospective cross-sectional comparative design, 28 matches at Arena MRV and 39 matches at previous stadiums (Mineirão and Independência) were examined, with detailed data provided by OPTA® Sportsdata via FBref. Results indicated that, although there was no statistically significant change in overall outcomes (points per match, wins/losses), the move to Arena MRV prompted a reconfiguration of the team’s on-field behavior, evidenced by differences of “large” magnitude in tactical-behavioral metrics. Defensively, there was a significant increase in clearances, shot blocks, and disciplinary cards (red and second yellow), suggesting greater intensity and aggressiveness, interpreted in light of the territoriality model and the arena’s “controlled hyperarousal.” Offensively, there was a significant decrease in pass attempts and total shots, indicating a more pragmatic style of play, possibly influenced by the pressure of the home environment and its potential psychological impacts (cortisol). Arena MRV, as a factor, may have promoted the gentrification of the fan base, altering the nature of support. This study demonstrates that the transition to Arena MRV as the exclusive home venue can reconfigure the internal dynamics of play and athlete behavior, offering a more complex understanding of the “home advantage” in football.
