This study examines the implementation of strategies for the development of a physical
activity program for children and youth with autism. The aim of the study was the
collaborative development of a sustainable physical activity program with families with
children with autism. A phenomenological approach was employed in the study, which used
participant observation that included conversations to obtain the lived experiences of the
participants. Close observations were made of the interactions between parents/assistants and
the children, the children and the environment and the parents/assistants, children and the
instructor. Thematic analysis was used to analyse the obtained data. The results indicated
that it is possible to develop a sustainable physical activity program for children with autism
if proper strategies are implemented. The study suggests that children with autism should be
afforded more opportunities for participation in physical activity. This study provided the
members of the Autism Association of Oslo with an opportunity to participate in physical
activity. The program development process also provided the parents that were involved with
the knowledge and guidelines for future physical activity possibilities
