My researches focus on physical education and sports of people with disabilities and of children with special educational needs. In recent years, my research has focused on the measurement of health-related fitness  of children with special educational needs (disabilities). I participated in the adaptation process of the Hungarian National Physical Fitness Test (so called: NETFIT) to children with special educational needs. Within the framework of a representative research, I examined the relationship between physical fitness and quality of life of children with disabilities.
