Membership in Sport or Exercise Groups Predicts Sustained Physical Activity and Longevity in Older Adults Compared to Physically Active Matched Controls

Abstract

Background Physical activity tends to decline in older age, despite being key to health and longevity. Previous investigations have focused on demographic and individual factors that predict sustained physical activity.

Purpose To examine whether engaging in physical activity in the context of sport or exercise group membership can protect against age-related physical activity decline.

Methods Drawn from the English Longitudinal Study of Ageing, participants were members of sport or exercise groups aged 50 and over (N = 2015) as well as nonmember controls, who were matched at baseline for age, sex, and physical activity levels (N = 1881). Longitudinal mixed effects models were used to assess the effect of sport or exercise group membership on physical activity and longevity across a 14-year follow-up.

Results Members of sport or exercise groups experienced an attenuated decline in both moderate and vigorous physical activity over a 14-year follow-up compared to physically active matched controls. Sport or exercise group members were also less likely to have died at follow-up, an effect that was mediated through sustained physical activity.

Conclusions Promoting membership in sport and exercise groups may be a beneficial strategy for supporting sustained physical activity and health among older people. Show more
