Based upon promising results from a pilot study among 424 sedentary older adults who were randomized to a physical activity intervention or a successful aging health education intervention, a Phase 3 multi-center randomized controlled trial is being conducted to compare a moderate-intensity physical activity program to a successful aging health education program in 1,600 sedentary older adults who are followed for an average of 2.7 years. The primary aim was to assess the long-term effects of the proposed interventions on the primary outcome of major mobility disability, defined as inability to walk 400 m.
