This study investigated the moderating role of sports participation types (no sport, individual sport, and team sport) on the association between adverse childhood experiences (ACEs) and reactive and proactive aggression in 593 individuals (69.0% females) from the community. ACEs positively influenced both types of aggression, with a stronger effect on reactive aggression. Additionally, participating in team sports (versus no sports) weakened the ACE-proactive aggression link, while participation in individual sports (versus no sports) did not moderate the association between ACEs and both types of aggression. The findings suggest that team sports may provide a protective factor against certain aggression tendencies linked to ACEs, emphasizing the nuanced impact of sports involvement on psychological outcomes among individuals in the community.
