Evaluation of a Peer-Led, Low-Intensity Physical Activity Program for Older Adults

Background Physical inactivity is a primary contributor to decreasing functional physical fitness and increasing chronic disease in older adults. Purpose This study assessed the health-related benefits of ExerStart for Lay Leaders, a 20-week, community based, peer-led, low-impact exercise program for older adults. ExerStart focuses on aerobic endurance, muscular strength, flexibility, and balance. Methods Using a pre/posttest evaluation design, researchers examined the effects of the program on 432 older adults in St. Louis, Missouri, and Houston, Texas. Participants completed self-report surveys as well as observed functional physical fitness assessments. Results Participants in ExerStart for Lay Leaders significantly improved their perceived satisfaction with body function, functional physical fitness, perceived overall health, and body mass index. Discussion This study adds to the evidence that older adults benefit from structured, peer-led exercise programs. The increased physical fitness, if maintained, may lead to a decrease in falls, adult obesity, and nursing home placements. Translation to Health Education Practice The current research has important implications for implementing outcome-based and cost-effective health education programs for older adults, including using peer leaders as a cost reduction technique to implement and disseminate research informed programs into community settings.
