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

我们的团队调查老年人的流动性的方法始于了解流动性如何与老年人的福祉相关。世卫组织对行动能力的定义包括促进获得高质量的行动辅助工具和装置，https://www.who.int/disabilities/media/news/personal_mobility/en/。我们将使用体力活动（PA）和运动的标准化定义如下：体力活动是由骨骼肌收缩产生的任何身体运动，导致热量需求大幅增加，超过静息能量消耗。运动是一种PA，包括有计划、有组织和重复的身体运动，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（上图），提供一个多学科团队与一系列老年人生活提供者（ExtraCare，https://www.extracare.org.uk/about-the-charity/the-trust-overview/）合作的整体方法，以评估更广泛背景下的流动性，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，可以量化和量化老年人如何继续动员和增加他们的身体活动。我们的建议围绕理解问题，共同制定战略，定制/个性化解决方案，并在真实的生活环境（丰富的环境）中测试和评估它们。通过与老年人、他们的正式和非正式照顾者以及老年人生活的提供者接触，在安全和福祉议程范围内理解流动性的整体方法至关重要。共同发展一种以人为本的理解，了解什么对老年人重要，将有助于理解流动性的影响和体育活动的广泛益处。我们将与一组不同（例如性别，种族，行动能力，认知功能和社会经济）的75岁及以上的老年人在他们的独立生活环境中合作。我们认为，在一系列背景下与老年人密切合作，并在全国各地的网站，但在一个组织（ExtraCare），可以在数字平台上提供最低限度的移动数据集。

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.
