The aim was to identify factors associated with physical activity participation among active (i.e. more than or equal to 10 000 steps per day) individuals with intellectual disability. Staff at day program and supported employment organizations were asked to identify individuals they believed were physically active. To verify participants were active, 7-day pedometer data were collected. Using these data, 13 participants met the inclusion criterion of 10 000 steps per day from 37 individuals identified by staff. Participants (n=13) ranged in age from 18 to 46 years (mean=34, SD= 8) and seven were male. In-depth semistructured interviews were conducted to explore the environmental and social supports for these high levels of physical activity. Three major themes were identified from content and thematic analyses. Key individuals and organizations were important in fostering initial interests and the development of skills. Coaches, staff and parents were important in "showing them how." For example, how to vacuum or stack produce, how to bowl, how to use weight training equipment or helping to plan a safe walking route. Motivation for initial and ongoing participation was associated with friendship and social connection. Practical support was needed for continued participation. In particular, transportation and affordable activities were very important. Fostering practical skills, supporting the social aspects of physical activity and keeping activities low cost are important enabling and reinforcing factors for physical activity among active persons with intellectual disability.
