Objective: To describe interventions designed to promote physical activity for youth with intellectual disabilities.
Materials and methods: A systematic review of nine databases until January 31, 2015 identified 213 citations. The inclusion criteria were: a) the study sample consisted of youth with intellectual disabilities, b) the study implemented an intervention to initiate, increase, or maintain physical activity, and c) quantitative or qualitative data were used to report the effectiveness of the intervention. Eleven articles from the 213 citations met this criterion.
Results: Nine studies reported significant increases in physical activity behavior.
Conclusions: Conclusions cannot be made regarding intervention components that impacted outcome variables, if the observed effects were specifically due to the intervention or if interventions could be maintained long-term. To advance the knowledge base in this area, a concerted effort should be made to increase rigor in study conceptualization and research design.
