The relationship between Mediterranean built environment and outdoor physical activity: evidence from GPS and accelerometer data among young adults in Barcelona

Having identified a set of geographic-based considerations, this study aims to analyse physical activity (PA) engagement and its relationship with its hosting environment in a Mediterranean metropolis. This is conducted based on GPS and accelerometer data from a sample of young adults living in different neighbourhood types. The results of the study show how outdoor moderate to vigorous physical activity (MVPA) in Barcelona mainly takes place on the streets. In accordance with previous research, green areas are also associated with PA, yet other urban spaces such as the street emerge as relevant while presenting significant intra-metropolitan differences. The main implication of this study is that geographically contextualised interpretations of the relationship between the built environment and PA may inform both future research and also targeted policies aimed at promoting regular outdoor physical activity.
