Effects of a Community-Based Familiarization Intervention on Independent Performance of Resistance-Training Exercise Tasks by Adults With Intellectual Disability.

★ The Verdict

An iPad visual schedule with short videos quickly teaches adults with ID to complete gym routines without staff help.

01Research in Context

01

What this study did

Obrusnikova et al. (2021) tested an iPad package for adults with intellectual disability. The package showed photos of gym machines plus short how-to videos.

Staff handed the iPad to each adult before a workout. The app used least-to-most prompts: first the picture, then the video, then spoken help.

Adults in the control group got the same gym time but no iPad. The study counted how many exercise steps each person did right on their own.

02

What they found

The iPad group hit more correct steps than the control group. The difference was large enough to matter in real life.

Most adults needed only the picture or the first video prompt. They kept the skill when staff stepped back.

03

How this fits with other research

Li et al. (2025) got the same kind of win with teens who taught themselves 27 daily tasks using phone videos. Both studies show people with ID can run their own learning when the prompt lives on a screen.

Rast et al. (1985) and Connis (1979) used paper photos and checklists to do the same job decades ago. The 2021 study simply swaps the paper for an iPad and moves the setting from a workshop to a gym.

Jackson et al. (2025) later pushed the idea further with an eight-week visual-exercise system. Their adults also got fitter, but they had no control group, so the 2021 paper still gives the cleaner evidence that the iPad package alone causes the gain.

Why it matters

If you support adults with ID in day programs or group homes, you can load a visual schedule plus mini-videos onto any tablet. Hand it over, let the app prompt, and fade yourself out. The person gets independent exercise, and you free up staff time for other goals.

03Original abstract

Adults with intellectual disability (ID) have significantly lower levels of fitness compared to the general population. The study examined the effects of a multicomponent familiarization intervention, consisting of a visual activity schedule and a video-enhanced system of least-to-most prompting, both displayed via an iPad, on the acquisition of resistance-training exercise tasks by adults with ID, aged 18-44 years, in a community fitness center. Twelve participants were randomly allocated to an experimental group (EG) and 12 to an active control group (CG). ANOVA revealed EG correctly and independently performed a significantly greater number of steps of four resistance-training exercise tasks compared with CG, relative to preintervention levels (p < .01). The intervention was effective in promoting functional performance of resistance-training exercise tasks among adults with ID.
