After-school interventions to increase physical activity among youth
Most children and adolescents do not meet the recommended 60 minutes or more of moderate to vigorous physical activity per day. One attractive approach to increasing physical activity in young people is providing activity through structured after-school programmes. This paper provides a review of the scientific literature on the effects of after-school programmes on physical activity in children and adolescents. After-school physical activity interventions provided mixed results; some increased children's physical activity, others did not. Although after-school programmes have the potential to help children and adolescents engage in regular, enjoyable physical activity, the research on these programmes is limited and, in some cases, methodologically weak. Additional, well-controlled studies are needed to identify the components of after-school programmes that promote physical activity and to determine the level of activity that can be attained when children and adolescents participate in these programmes.
