In recognising the ableism disabled children and young people are exposed to through sport, this research investigated the mechanisms for the reproduction of ableism in and through coaching. Through semi-structured interviews, the learning journeys of ten disability sport coaches were explored. Drawing on a critical sociological framework, data analysis involved an abductive approach with Bourdieu’s sociology and ableism as sensitising concepts. In addition, Charlie’s story, the experiences of a young disabled person, is presented as a further sensitising concept. By applying Bourdieu’s theory and practice in conjunction with ableism, the interrelatedness of the theories was demonstrated. The research found that disability sport exists as a sub-field, kept at arm's-length from the mainstream sport field. As such, coaches’ mobility between sport and disability sport was constrained and often serendipitous. Further, disability knowledge was marginalised in coach education and positioned as optional and ‘other’. This optional othering is a manifestation of the institutionalised ableism of the coach education system. Further, the pedagogies used within coach education reinforced enlightened and benevolent forms of ableism. The analysis suggested that ableism is present in the field, habitus and distribution of capital and is, therefore, hard to challenge and is predisposed to reproduction. The field’s socialising conditions transmit certain orientations towards disability, bodies, and sport. Dispositions toward disability were informed by the field of power and its inherent compulsory able-bodiedness. The findings evidenced that ableism exists as doxa (accepted practice that goes without saying) within the field of sport and sub-field of disability sport. Ableism is woven into the fabric of coaching and forms a part of the classifying principles which are instilled in coaches’ habitus through doxa. Thus, it is ableism that guides how coaches perceive, interpret and act in the disability sport field. Furthermore, doxa (ableism) was more influential on coaches’ learning than coach education. Understanding ableism as doxa within the field of disability sport provides critical insight into how social and symbolic structures constrain coach learning. No matter how well-meaning coaches are, ableism is inscribed in habitus through doxa.
