Instructing children with Autism Spectrum Disorder: Examining swim instructors' knowledge building experiences.

Background: Although there has been a notable increase in Autism Spectrum Disorder (ASD) diagnoses over the past twenty years, children with ASD continue to be underrepresented in physical activity opportunities. Swimming lessons have been suggested as an ideal form of physical activity for this population, but studies exploring instructors' experiences gaining knowledge specific for instructing these swimmers remains limited. Research in this area is warranted, as drowning is a leading injury cause of death for persons with ASD.
