Young people with disabilities participate to a lower extent in organized sport than their peers without disabilities. Research in this matter has previously focused on the complex barriers that restrict participation in sports clubs, rather then what can facilitate participation and inclusive activities. There is a need to study real examples of how sports clubs can include children and youth with disabilities in the sport program. An overview of inclusion in organized sports regarding children and adolescents with disabilities is lacking today. Therefor the aim of this study is to increase the understanding of how sports clubs include children and adolescents with disabilities in their activities. The results of this systematic search on documented inclusive physical activities within sport clubs shows that are few peer-reviewed studies that describe how (i) children and young people with disabilities are included in sports clubs’ regular, ongoing activities. The sports clubs rather worked with short term intervention-based activities in team-sports settings (what ii). The main documented reasons for sport clubs to inclusion in organized sport (why iii) were to increase the participation of youth with disabilities and to promote social contact between children with and without disabilities. The lack of documentation and the limited collective knowledge-based is discussed as a problem while implementing a successful inclusive approach on adapted physical activity in organized sport settings for all people longer time in life.
