Older adults are often advised to engage in more moderate-to-vigorous physical activity (MVPA). Although MVPA offers significant health benefits, focusing solely on MVPA may be difficult for many in this population due to their typically higher levels of sedentary behavior (SB). Increasing light-intensity physical activity (LIPA) can offer similar health benefits and be a more achievable starting point for inactive older adults. The 24-hour activity cycle provides a conceptual model that can assist healthcare providers in promoting physical activity. This model emphasizes the interaction between four key behaviors (i.e., sleep, sedentary behavior, LIPA, and MVPA) and presents a holistic approach to optimizing the balance of these activity behaviors. This article outlines strategies to help older adults increase their physical activity and reduce sedentary time within the 24-hour activity cycle, promoting sustainable, long-term behavior change in this population.
通常建议老年人进行更多中等至剧烈强度的体育活动（MVPA）。尽管MVPA对健康有显著益处，但由于该人群通常久坐行为（SB）水平较高，许多老年人可能难以仅专注于MVPA。增加轻度强度体育活动（LIPA）也能带来类似的健康益处，并且对于缺乏运动的老年人来说是一个更容易实现的起点。24小时活动周期提供了一个概念模型，可帮助医疗保健提供者促进体育活动。该模型强调四种关键行为（即睡眠、久坐行为、LIPA和MVPA）之间的相互作用，并提出了一种整体方法来优化这些活动行为的平衡。本文概述了一些策略，以帮助老年人在24小时活动周期内增加体育活动并减少久坐时间，促进该人群可持续的长期行为改变。
