Co-developing a sustainable, meaningful, digital platform to enhance mobility and active ageing of community dwelling older adults (>75 years).

我们的团队研究老年人流动性的方法始于理解流动性如何与老年人的福祉相关。世卫组织对移动性的定义包括促进获得高质量的移动性辅助设备和设备，https://www.who.int/disabilities/media/news/personal_mobility/en/。我们将使用一个标准化的体力活动(PA)和锻炼的定义如下：体力活动是由骨骼肌收缩产生的任何身体运动，导致卡路里需求大幅增加超过静息能量消耗。运动是一种由计划的、有组织的和重复的身体运动组成的一种PA，旨在改善和/或保持身体健康的一个或多个组成部分。我们的研究团队将遵循世界卫生组织的老年友好城市模式(如上图)，由一个多学科团队与一连串支持生活的提供者(ExtraCare，https://www.extracare.org.uk/about-the-charity/the-trust-overview/)合作，提供全面的方法，在更广泛的背景下评估移动性；老年人的健康水平、物理环境、社会环境和市政服务。ExtraCare中的老年人社区/村庄提供了一个理想的环境，以确定和量化老年人人口如何继续动员和增加他们的体力活动。我们的建议围绕了解问题、共同开发战略、定制/个性化解决方案，并在现实生活环境(丰富的环境)中对其进行测试和评估。至关重要的是，通过与老年人、他们的正式和非正式照顾者以及有保障生活的提供者接触，在安全和福祉议程中理解流动性的综合办法至关重要。共同发展以人为本的对老年人重要的理解，将有助于理解行动的影响和体力活动的广泛益处。我们将在75岁及以上的独立生活环境中与一群不同的老年人(如性别、种族、流动性、认知功能和社会经济)合作。我们认为，在一系列背景下与老年人密切合作，在全国各地但在一个组织(ExtraCare)内与老年人密切合作，可以在数字平台上提供最低限度的移动性数据集。

Our team approach to investigating mobility in old age starts with understanding how mobility relates to the well-being of an older person. The WHO definition of mobility includes facilitating access to quality mobility aids and devices, https://www.who.int/disabilities/media/news/personal_mobility/en/ . We will use a standardised definition of physical activity (PA) and exercise as follows: Physical Activity is any bodily movement produced by the contraction of skeletal muscles that result in a substantial increase in caloric requirements over resting energy expenditure. Exercise is a type of PA consisting of planned, structured, and repetitive bodily movement undertaken to improve and/or maintain one or more components of physical fitness.Our research team will follow the WHO model of age-friendly cities (figure above) to deliver a holistic approach from a multidisciplinary team working with a chain of supported-living providers (ExtraCare, https://www.extracare.org.uk/about-the-charity/the-trust-overview/ ) to assess mobility in its wider context; an older person's fitness level, physical environment, social environment, and municipal services. Older people communities/villages in ExtraCare offer an ideal environment to qualify and quantify how a population of older people continue to mobilise and increase their physical activity. Our proposal pillars around understanding the problem, co-developing strategies, customising/ individualising solutions and testing and evaluating them in real life settings (enriched environment). A holistic approach to understanding mobility within a safety and well-being agenda by engaging with older people, their formal and informal carers, and providers of supported-living is crucial. Co-developing a person-centred understanding of what matters to older people will enable understanding the impact of mobility and the wide range of benefits from physical activity. We will work with a group of diverse (e.g. gender, ethnicity, mobility, cognitive functions and socio-economics) older people aged 75 and above in their independent-living environment. We argue that working closely with older people in a range of contexts, and sites across the country but within one organisation (ExtraCare), can deliver a minimum mobility-dataset on a digital platform.
