RESUMEN
This review summarized the researches about physical activity levels, measurement methods, influencing factors and interventions for children and adolescents with intellectual disability. The physical activity levels of children and adolescents with intellectual disability were low, and their health status was not optimistic. The joint efforts of individuals, families and the society were needed to improve their levels of physical activity. The effectiveness of existing physical activity intervention methods should be further discussed. Therefore, focusing on the health demands of children and adolescents with intellectual disability, more researches are needed about in-depth analysis of the dose-effect relationship between physical activity and health indicators, and exploring of effective intervention for physical activity in the future.
