This study explores the impact of parental involvement in both education and sports on the academic and sports performance of primary school students. A questionnaire survey was conducted among 7th and 8th-grade students in three Hungarian primary schools (N = 121). Based on parental involvement, three groups were formed: children of parents not involved in education or sports (N = 33), children of parents involved in education only (N = 38), and children of parents involved in both education and sports (N = 47). Data were analyzed using cluster analysis, factor analysis, Chi-square tests, ANOVA, and linear regression. Results showed that children of parents involved in both education and sports were more likely to achieve awards in sports, participate in talent management programs, and excel in national competitions. They also showed higher intent to continue engaging in sports. In contrast, children of parents involved in education only were more likely to achieve academic awards. Personality traits such as obsessive passion (OP) were more common among children of non-involved parents, while children of involved parents showed lower levels of OP. The study found a positive correlation between parental involvement in both education and sports and the academic and sports performance of their children. It also found that parental involvement in both areas was a negative predictor of OP. The study highlights the importance of parental involvement in both education and sports for the academic and sports performance of children, and suggests that strength-based parenting can be beneficial in this context. The study also notes that parental involvement in both areas can help prevent obsessive passion in children. The study concludes that parental involvement in both education and sports has a positive impact on the academic and sports performance of children, and that this involvement is a negative predictor of obsessive passion. The study also suggests that future research should explore the effects of parental involvement in both education and sports on the academic and sports performance of children, and the role of mediating factors in this relationship.This study explores the impact of parental involvement in both education and sports on the academic and sports performance of primary school students.
