Objective Assessment and Promotion of Physical Activity in Elderly

Study Overview
=================
Brief Summary
-----------------
The purpose of the present study is to evaluate the short-term and long-term effects of a cycle ergometer program on physical activity and physical fitness in elderly (65+). Therefore, physical activity, physical fitness and functionality are measured at baseline, after 10 weeks (after the intervention period), after 6 months and after 1 year. Different coaching techniques (to promote the use of a cycle ergometer and cycle ergometer program) will also be evaluated. What is the best (coaching) approach for long-term adherence (physical activity)?

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change in objective and subjective measures of degree of physical activity | Physical activity will be measured using a standardized questionnaire and a Sensewear. A Sensewear is an activity monitor (accelerometer) carried on the upper arm during several days and registers the amount of physical activity. | baseline, 10 weeks, 6 months, 1 year | 
| Change in objective measures of physical fitness | Physical fitness will be measured using a standardized Six-Minute Walk Test and a Six-Minute Cycle Test. | baseline, 10 weeks, 6 months, 1 year | 
| Change in objective measures of functionality | Functionality will be measured using the standardized The Physical Performance Test and 2 strength tests (hand grip and knee extension). | baseline, 10 weeks, 6 months, 1 year | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change in mental well-being | Standardized questionnaire | baseline, 10 weeks, 6 months, 1 year | 
| Change in motivation to be physically active | Standardized questionnaire | baseline, 10 weeks, 6 months, 1 year | 
| Change in self-efficacy to be physically active | Standardized questionnaire | baseline, 10 weeks, 6 months, 1 year |
