Physical activity, movement, behaviour and the living environment are closely intertwined. Adequate physical activity and the fostering of motor skills throughout life form an essential foundation for healthy aging. Everyday environments (i.e. play areas, workplaces, homes, green spaces, neighborhoods) play a crucial role in this process—they can either act as barriers or facilitators to being physically active. How do people adapt their actions to the environment across the timescales of performance, learning and aging? How do people perceive and act upon the possibilities for acting in their living environment? To answer these questions, we conduct field research in real-world settings, investigating -among other things-, the benefits of green exercise for elderly, which jumping stone configurations are most attractive, how the layout of a living environment affects the daily lives of citizens.
