This study investigates the impact of parental involvement in both academic and sports activities on the academic and sports performance of primary school students in a Hungarian city. The research focuses on three groups: children of parents involved in education only, parents involved in sports only, and parents involved in both education and sports. A questionnaire survey was conducted among 7th and 8th-grade students from three primary schools, with 118 participants. The results show that children of parents involved in both education and sports are more likely to excel in sports performance, receive awards for sports achievements, and be involved in talent management programs. They also exhibit a higher commitment to regular and competitive sports activities. In contrast, children of parents involved only in education are more likely to excel academically. The study also finds that obsessive passion (OP) is more prevalent among children of non-involved parents, while strength-based parenting (SBP) is protective against OP. The findings suggest that a balanced approach to parental involvement in both education and sports can enhance academic and sports performance, while overemphasis on one area may lead to OP. The study concludes that SBP has a positive interrelation with academic and sports performance, and future research should explore the broader socio-cultural and demographic backgrounds of parental involvement.This study investigates the impact of parental involvement in both academic and sports activities on the academic and sports performance of primary school students in a Hungarian city.
