Background
Optimal physical activity and protein intake are shown to be beneficial interventions to prevent and/or treat the decline in daily functioning in the older adults.
Several group based weekly exercise programs aim to promote physical activity, however these programs may not be effective in improving physical functioning and quality of life. To optimize the training program for community dwelling older adults, new developed intervention strategies are suggested. A suggestion is the use of a home-based exercise program, based on functional exercise, with digital support, providing a personalized exercise program. In addition, an increase in dietary protein intake in combination with exercise training may further improve physical functioning in community dwelling older adults.
Methods / Design
The VITAMIN study will be a cluster randomized controlled trial with 3 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 home- based personalized training program group (VITA group, n=80), 3). Digitally supported home-based personalized training program group plus dietary protein counselling (VITA-Pro group, n=80). (Table 1)

Discussion
To our knowledge, the VITAMINE study is the first study that investigates cognitive, behavioral, psychosocial, physical, body composition and nutritional factors simultaneously. The current study will provide novel insights in the impact of home-based exercise with use of technology and protein intake in the population of community dwelling elderly.
Registered clinical trial: NL56094.029.16 / NTR (TC = 5888)
Figure 1. Schematic overview of the study scheme
The VITAMIN intervention aims to evaluate the 6 months effectiveness as well as 12 months follow-up retaining effect of the digitally supported home-based exercise program as well as the additional value of dietary protein on physical functioning in community dwelling older adults. Primary outcome will be measured using the Modified Physical Performance Test (M-PPT) and relevant secondary and observational outcomes includes; cognitive functioning, quality of life, body composition, physical functioning and dietary intake.
