Study summary

The multi-disciplinary and translational VOILA project presents a unique intersection between gut, immuno-metabolic, and musculoskeletal health. The main goals of the project are to develop biomarkers for healthy aging and prevent disease by maintaining quality of life in older adults. Within this umbrella project, the multimodal VOILA lifestyle intervention study will assess the impact of a twelve-week strength training and nutritional intervention in older adults with different degrees of mobility. The study will improve the current understanding of the complex relationship between gut and muscle health in different segments of mobility and obtain an insight into the heterogeneity of responsiveness between individuals.

Interventions

  • Combination productVOILA

    Participants will be given dietary supplement powder containing protein, galactooligosaccharide (GOS), vitamin D, and calcium throughout the twelve weeks of intervention. This will be accompanied with a resistance training regime whereby participants will train three times a week for the three months. A variety of measurements will be carried out at baseline and at endline.

References and documents

Individual participant data

Plan to share: Yes — Clinical data in this project will only be shared within the constraints of the informed consent. Furthermore for all permitted sharing, a data access committee (DAC) has been established in which the responsible PI of each center is present, a secretary and data manager. The data will primarily be analysed by the centers generating the data and associated partners in the VOILA project. In a later stage data access can be requested at the central contact person P.E. Slagboom (p.slagboom@lumc.nl ) and permitted by the DAC and analysed locally provided a data access agreement is signed.
