Best-Practice Physical Activity Programs for Older Adults: Findings From the National Impact Study

摘要

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.
