StayFitLonger. Preventive Effects of a Combination of Non-drug Interventions (Physical, Cognitive and Social) in Healthy Elderly Subjects: Multicentre Randomised Controlled Trial.

Multimodal training, including physical and cognitive activities, has been associated with a reduction in age-related physical and cognitive decline. Therefore, combining these activities into a home-based computerized training program may represent a powerful approach to foster independent life at home. The StayFitLonger study is a 6-month multi-site randomized controlled, double-blind trial, which tests the efficacy of a home-based computerized intervention that combines physical and cognitive exercises through virtual coaching to enhance motivation. In Switzerland, Canada and Belgium, a total of 128 older participants will be recruited and randomly assigned to one of two physical and cognitive home-based interventions for 6 months: StayFitLonger or active control training. The StayFitLonger intervention provides physical and cognitive training exercises, feedback and instructions through a virtual coach to optimize motivation. It also offers social and psycho-educational contents. Monthly supervision (home-visits and phone calls) will be provided during this 6-month intervention. Outcomes will be measured at baseline, and after 6 months of training. This study will demonstrate the feasibility, sustainability and efficacy of a home-based multi-domain intervention program allowing further development and possible commercialization of a scientifically validated training program to slow down cognitive and physical decline.
