Both the diagnosis of autism spectrum disorder (ASD) and obesity among children with ASD are on the rise. A growing body of evidence indicates a concern about the health consequences of obesity and improving with ASD. Physical activity is well known as a means for reducing the risk of obesity and improving quality of life. Many studies have been conducted over the years to address the effectiveness of physical activity for children with ASD. However, although community programs exist to get children involved in physical activities, few of them meet the needs of children with ASD. For this project, an in-depth review of the literature was conducted with the purpose of identifying the effectiveness of physical activities for children with ASD and determining what hinders their participation, as well as what would make physical activity programs viable for this population.
