Physical activity interventions among older adults: a literature review

Physical activity (PA) is important in the management of chronic illness among older adults worldwide. Researchers have conducted several intervention studies to increase PA behavior in this population. This review of the past 12 years of relevant PA intervention research among adults aged 60 years and older systematically summarized research findings, identified characteristics of successful interventions, and proposed areas of future research. There were 20 studies reviewed for this article, most employing a combination of cognitive-behavioral intervention design. Cognitive-based only and combination interventions were more successful in changing PA behavior; however, behavioral-based interventions demonstrated more long-term changes in PA behavior. Among theory-based interventions, self-efficacy was the most commonly operationalized construct. Findings from this review may inform future primary research to promote PA behavior among older adults, as well as gerontological clinical practice.
