This book brings together academic work on Special Olympics and specifically on the social inclusion of people with intellectual disabilities in various sport contexts and other areas of life, by ways of both empirical research and theoretically informed papers. Inclusion in sport is a topic that is mostly explored in connection with the participation of people with disabilities in general. In public debates on inclusion and sport in the global society, participation is predominantly discussed in a normative way, describing it as an "all-out effort to end discrimination against people with intellectual disabilities". With this international collection, the authors seek to contribute to an interdisciplinary understanding of Special Olympics in context of inclusion debates and establish a foundation for future scholarship.
