Do sedentary older adults benefit from community-based exercise? Results from the Active Start program.

PURPOSE: This study assessed the effectiveness of Active Start, a community-based behavior change and fitness program, designed to promote physical activity among sedentary community-dwelling older adults. DESIGN AND METHODS: A quasi-experimental design was used. Data were analyzed using a within-group pretest-post-test design to calculate changes in the intervention group and changes in the waitlist comparison group. Further analyses were conducted after the comparison group completed the intervention. Paired t tests were employed to analyze unadjusted mean changes in physical performance measures from pretest to post-test. Repeated measures analysis of covariance (using SAS Proc Mixed) was then conducted to calculate the adjusted mean change for the intervention group.
RESULTS: Significant improvement was found on all performance measures (strength, flexibility, and balance) for the intervention group as a whole. Similar improvements were found among subgroups (Whites, African Americans, and Hispanics). No significant changes were found in the comparison group when they were in the control condition; however, they significantly improved on all measures after completing the intervention. IMPLICATIONS: This study suggests that a community-based physical activity program benefits sedentary, racially, and ethnically diverse older adults by coupling a behavioral change support group and fitness classes.
