老年人的身体活动（PA）水平随着年龄的增长而下降。在老年人中遵守当前英国PA指南的流行率和相关性尚未使用客观测量的PA进行研究，该PA可以精确地检查PA是否在指定长度和强度的发作中进行。来自英国25个城镇的70-93岁的自由生活男性和女性，参与了平行的正在进行的基于人群的队列研究，被邀请（通过邮寄）在2010-12年在臀部佩戴GT 3x加速计一周。对UK PA指南的依从性定义为≥150分钟/周的中度或剧烈PA（MVPA）发作≥10分钟;检查不同强度和持续时间的影响。1 593名男子和857名妇女参加了调查（答复率分别为51%和29%）。15%男性和10%女性在持续≥10分钟的发作中达到≥150分钟/周的MVPA（定义为>1040 cpm）。MVPA定义为>1952 cpm，患病率分别为7%和3%。那些坚持指导方针的人更年轻，慢性健康状况更少，抑郁症更少，活动受限更少，但运动自我效能和运动结果期望更高。他们对当地环境的社会活动和休闲设施的评价更高，有一个不错的地方去散步，天黑后感到安全，他们每周离开家的日子更多，更有可能使用主动交通工具（骑自行车或步行），并定期遛狗。很少有老年人达到目前的PA指南。将中等强度活动的持续时间延长到10分钟或更长的健康促进可以在老年人中产生重要的健康收益。然而，未来的研究需要澄清在持续10分钟或更长时间的时间内达到PA的指导量是否对降低慢性疾病风险以及改善心脏代谢风险因素至关重要。
Physical activity (PA) levels in older adults decline with age. The prevalence and correlates of adherence to current UK PA guidelines in older adults has not been studied using objectively measured PA, which can examine precisely whether PA is carried out in bouts of specified length and intensity. Free living men and women aged 70–93 years from 25 towns in the United Kingdom, participating in parallel on-going population based cohort studies were invited (by post) to wear a GT3x accelerometer over the hip for one week in 2010–12. Adherence to UK PA guidelines was defined as ≥150 minutes/week of moderate or vigorous PA (MVPA) in bouts of ≥10 minutes; the effect of different intensities and durations were examined. 1593 men and 857 women participated (responses 51% and 29% respectively). 15% men and 10% women achieved ≥150 minutes/week of MVPA (defined as >1040 cpm) in bouts lasting ≥10 minutes. With MVPA defined as >1952 cpm, prevalences were 7% and 3% respectively. Those adhering to guidelines were younger, had fewer chronic health conditions, less depression, less severe mobility limitations, but higher exercise self-efficacy and exercise outcomes expectations. They rated their local environment more highly for social activities and leisure facilities, having somewhere nice to go for a walk and feeling safe after dark, They left the house on more days per week, were more likely to use active transport (cycle or walk) and to walk a dog regularly. Few older adults attain current PA guidelines. Health promotion to extend the duration of moderate-intensity activity episodes to 10 minutes or more could yield important health gains among older adults. However future studies will need to clarify whether attaining guideline amounts of PA in spells lasting 10 minutes or more is critical for reducing chronic disease risks as well as improving cardiometabolic risk factors.
