Study & Design

• Study Type: interventional
• Study Design: Not specified

Primary Outcome Measures

Name	Time	Method
The primary outcome is the change in physical activity. It is assessed at baseline, at 3 and 9 months via triaxial accelerometers (worn over the course of 7 days).

Secondary Outcome Measures

Name	Time	Method
Further, functional, cognitive and mental health and other relevant parameters that are associated with physical activity will be assessed. These include physical fitness (gait speed via 4-meter-walk-test; handgrip via dynamometer; cardiovascular fitness via 2-minute-step-test) and cognitive fitness (via Mini Mental Status Test – short version), quality of life (EuroQol-5D-3L), well-being (Satisfaction with Life Scale), self-efficacy and intention (based on the Health Action Process Approach Model), body satisfaction (Physical Self-Description Questionnaire), depressive symptoms (Center for Epidemiological Studies Depression Scale), and fear of falling (Elderly Fall Screening Test). Outcomes are assessed at baseline, 3 and 9 months.
