Physical activity is remarkably important for every individual’s psychological and physical development, and many researches have proven positive effects it can have on psychomotor development of people with disabilities. Term “disability” is very versatile and includes wide spectrum of disabilities that a child can have (from hearing or vision impairment, physical and intellectual disabilities to behavior disorders). Since physical activity levels and life quality of children with disabilities are significantly connected, it is important to determine to what extent do children with disabilities participate in different forms of physical activity. Research is conducted using Fels Physical Activity Questionnaire for Children, which is constructed to determine levels of physical activity of children aged 7-19, with a goal of determining levels of physical activity of children with disabilities enrolled to primary school ranging from 1st to 4th grade. Results indicated low levels of total physical activity, as well as low levels of total physical activity while doing housework, playing sports in school, outside of school and during free time. Physical activity during free time has highest index result, while lowest physical activity index result was shown in participating in organized sports. These results are compared with research results from research conducted on children with disabilities using different methods as well as some conducted on samples of children without disabilities but using the same method. Low levels of physical activity of children with disabilities shown in results indicate the need for greater inclusion of that group in organized sports and other forms of physical activity.
