Sufficient physical activity can prolong the ability of older adults to live independently. Community-based exercise programs can be enhanced by regularly performing exercises at home. To support such a home-based exercise program, a blended intervention was developed that combined the use of a tablet application with a personal coach. The purpose...
Aging is associated with a decline in the ability to carry out daily tasks. Physical activity can delay or diminish the decline and increase the ability of older adults to live independently at home. Performing home-based exercises can help older adults achieve the recommended levels of physical activity. Technology allows exercise programs to be t...
Digitally supported dietary counselling may be helpful in increasing the protein intake in combined exercise and nutritional interventions in community-dwelling older adults. To study the effect of this approach, 212 older adults (72.2 ± 6.3 years) were randomised in three groups: control, exercise, or exercise plus dietary counselling. The dietary...

Background
Effective and sustainable interventions are needed to counteract the decline in physical function and sarcopenia in the growing aging population. The aim of this study was to determine the 6 and 12 month effectiveness of blended (e‐health + coaching) home‐based exercise and a dietary protein intervention on physical performance in commun...
Physical activity can prolong the ability of older adults to live independently at home. A blended intervention was developed to sustain healthy aging. During a clinical trial 133 participants, with an average age of 71 years old, received a tablet and coaching to support them in performing home-based exercises for 6 months. To investigate how the...
Background:
Physical activity can prolong the ability of older adults to live independently. Home-based exercises can help achieve the recommended levels. A blended intervention was developed to support older adults in performing home-based exercises. A tablet and a personal coach were provided to facilitate the self-regulation of exercise behavio...
Background: For older adults, physical activity is vital for maintaining their health and ability to live independently. Home-based programs can help them achieve the recommended exercise frequency. An application for a tablet computer was developed to support older adults in following a personal training program. It featured goal setting, tailorin...

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, we...

Background:
Physical activity can prevent or delay age-related impairments and prolong the ability of older adults to live independently. Community-based programs typically offer classes where older adults can exercise only once a week under the guidance of an instructor. The health benefits of such programs vary. Exercise frequency and the durati...
Ageing is associated with a decline in daily functioning and mobility. A physically active life and physical exercise can minimize the decline of daily functioning and improve the physical-, psychological- and social functioning of older adults. Despite several advantages of group-based exercise programs, older adults participating in such interven...
Background: Meer Bewegen voor Ouderen is a Dutch umbrella organization that aims to improve the physical, social and psychological wellbeing of senior citizens. Weekly 300,000 older adults participate nationwide in community based ‘gym classes’. In order to achieve the recommended amount of physical activity, the participants are stimulated to repe...
Handheld displays leave little space for the visualization and navigation of spatial layouts representing rich information spaces. The most common navigation method for handheld displays is static peephole navigation : The peephole is static and we move the spatial layout behind it (scrolling). A more natural method is dynamic peephole navigation:...

Questions
Question (1)
Hi
I have run a RCT with three arms. The independent and dependent variable are measured pre- and post intervention. The mediating variable has been measured repeatedly (26 data points per participant).
How can this be analysed? I am not sure how to proceed (I have no experience in mediation analysis, so I am a rookie)
See the attachment for more details
Projects
Project (1)
This VITAMIN clinical trial is conducted at the Amsterdam University of Applied Sciences (AUAS) in collaboration with health and exercise professionals in the city. Unique are the new developed digital home-based exercise training program and the participation of students of multiple educational tracks in this research. This results in a multidisciplinary approach and innovative interventions for older adults to maintain a healthy lifestyle. The aim of the study: To evaluate the effectiveness of a digitally supported home-based exercise training program and increased dietary protein intake on physical performance in community dwelling older adults.
