BACKGROUND
Increased physical activity and dietary protein intake are promising interventions to prevent or treat the age-related decline in physical performance in older adults. There are well-controlled exercise as well as dietary intervention studies that show beneficial effects on physical performance in older adults. In practice, however, weekly group based exercise or nutritional programs may not be as effective. To optimise these exercise programs for community dwelling older adults, a digitally supported and personalised home-based exercise training program has been designed aiming to improve physical performance in older adults. In addition, a protein intervention in combination with the training program may further improve physical performance in older adults.
METHODS
The VITAMIN study will be a cluster randomised controlled trial with three parallel arms. In total, 240 community dwelling older adults (≥ 55 years) participating in weekly group exercise are randomly allocated into: 1) regular weekly exercise program (Control group, n = 80), 2) digitally supported personalised home-based exercise training program group (VITA group, n = 80) and 3) digitally supported personalised home-based exercise training program group plus dietary protein counselling (VITA-Pro group, n = 80). The VITAMIN study aims to evaluate effectiveness of the digitally supported personalised home-based exercise training program as well as the additional value of dietary protein on physical performance after 6 months. In addition, a 12 month follow-up measurement will assess the retaining effect of the interventions. Primary outcome is physical performance measured by the Modified Physical Performance Test (M-PPT) and relevant secondary and observational outcomes include habitual physical activity and dietary intake, body composition, cognitive performance, quality of life, compliance and tablet usage. Data will be analysed by Linear Mixed Models.
DISCUSSION
To our knowledge, the VITAMIN study is the first study that investigates the impact of home-based exercise, protein intake as well as use of persuasive technology in the population of community dwelling older adults.

背景
增加身体活动和膳食蛋白质摄入是有希望的干预措施，可以预防或治疗老年人身体活动能力随年龄下降。有许多经过良好控制的运动和饮食干预研究表明，这些干预措施对老年人的身体活动能力有益。然而，在实践中，每周的小组基础运动或营养计划可能效果不佳。为了优化这些针对社区居住老年人的运动计划，设计了一种数字化支持和个性化的家庭基础运动训练计划，旨在提高老年人的身体活动能力。此外，蛋白质干预与训练计划相结合可能进一步提高老年人的身体活动能力。
方法
VITAMIN 研究将是一项三臂平行的集群随机对照试验。共有 240 名参加每周小组运动的社区居住老年人（≥55 岁）被随机分为三组：1）常规每周运动计划（对照组，n=80）、2）数字化支持个性化家庭基础运动训练计划组（VITA 组，n=80）和 3）数字化支持个性化家庭基础运动训练计划组加膳食蛋白质咨询组（VITA-Pro 组，n=80）。VITAMIN 研究旨在评估数字化支持个性化家庭基础运动训练计划的有效性以及膳食蛋白质对 6 个月后身体活动能力的额外价值。此外，为期 12 个月的随访测量将评估干预措施的保留效果。主要结局是通过改良体能测试（M-PPT）测量的身体表现，相关的次要和观察结局包括习惯性体力活动和饮食摄入、身体成分、认知表现、生活质量、依从性和片剂使用。数据将通过线性混合模型进行分析。
讨论
据我们所知，VITAMIN 研究是第一项调查家庭基础运动、蛋白质摄入以及在社区居住老年人中使用劝导技术对身体活动能力影响的研究。
