| Exercise Physiology and Fitness Symposium—Physical Activity Space: Concept, Measurements, and Applications |
| To fully understand the relationship between people's physical activity behavior and their surrounding environment, a new concept/measure is greatly needed. This is because commonly used physical activity measures, such as questionnaires or activity monitors, measure only the physical activity itself; not the surrounding environment and their interactions. To address the need, Zhu (2003) proposed a new concept/measure called "physical activity space (PAS)," which is defined as "the area, or space, within which an individual spends time and engages in physical activities." An individual's physical activity space is comprised of a home base, or residence; other activity sites (e.g., workplace, schools, stores, restaurants, fitness clubs and recreational areas where physical activities are regularly engaged); and the pathways traveled to and from home and other activity sites. The size and shape of an individual's physical activity space varies depending on the activities the individual is obligated or chooses to perform, the modes of transportation available, and the geographical locations where activities may take place. The intent of this symposium is to introduce the concept of PAS and related measurement and application issues, including its definition, its relationship with physical activity, how to measure it using the latest technology, how to summarize it using spatial statistics and database, and major research application areas and challenges. The GeoStats GeoLoggerTM, a spatial and temporal measurement device based on GPS technology, will be introduced and illustrated. Finally, two application examples that measure PAS for blind individuals and older adults will be presented. |
