背景
尽管体育活动是健康和长寿的关键，但随着年龄的增长，体育活动往往会减少。以前的调查集中在预测持续体力活动的人口统计学和个人因素上。
目的
研究在运动或锻炼小组成员的背景下从事身体活动是否可以防止与年龄相关的身体活动下降。
方法
来自英国老龄化纵向研究，参与者是50岁及以上的运动或锻炼组成员（N = 2015）以及非成员对照组，他们在基线时的年龄，性别和体力活动水平（N = 1881）匹配。纵向混合效应模型用于评估运动或锻炼组成员资格对14年随访期间身体活动和寿命的影响。
结果
在14年的随访中，运动或锻炼组的成员与体力活动匹配的对照组相比，中度和剧烈体力活动都出现了衰减下降。运动或锻炼组成员在随访时死亡的可能性也较小，这一效应是通过持续的体力活动介导的。
结论
促进参加体育和锻炼团体可能是支持老年人持续体育活动和健康的有益战略。
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.
