Objectives: We assessed the impact of existing best-practice physical activity programs for older adults on physical activity participation and health-related outcomes.
Methods: We used a multisite, randomized trial with 544 older adults (mean age 66 years) and measures at baseline, 5, and 10 months to test the impact of a multiple-component physical activity program compared with results for a control group that did not participate in such a program.
Results: For adults who participated in a multiple-component physical activity program, we found statistically significant benefits at 5 and 10 months with regard to self-efficacy for exercise adherence over time (P < .001), adherence in the face of barriers (P = .01), increased upper- and lower-body strength (P = .02, P = .01), and exercise participation (P = .01).
Conclusions: Best-practice community-based physical activity programs can measurably improve aspects of functioning that are risk factors for disability among older adults. US public policy should encourage these inexpensive health promotion programs.
