"We are not just measuring physical activity, but we are linking it to a location using small activity monitors and global positioning system devices," said Philip J. Troped, an assistant professor of health and kinesiology. "A better understanding of how neighborhood environments influence people's behaviors could help us to get more people to be physically active and healthy."
For example, a better understanding of where physical activity occurs and the characteristics of those areas could be used to develop more tailored intervention programs or messages to encourage physical activity at those locations, as well as to shape policy for urban planning and transportation systems.
"Research has shown that there is a positive relationship between characteristics of neighborhood-built environments and physical activity, but one of the limitations is that the data have been collected with devices that only measure activity, so assumptions are made that physical activity is mostly happening around where people live - and that may not be the case," he said.
Such built environments are humanmade and can reflect urban planning features such as how neighborhoods are designed, convenience of trails and parks, width of sidewalks, and the connectivity of transportation routes.
Troped and his research team found that most of the moderate to vigorous physical activity people participated in took place outside a 1-kilometer buffer zone around their home.
When moderate to vigorous physical activity occurred within 1 kilometer of a person's home, the buffer zone had a higher density of residential housing, more connected streets and a greater mix of residential and commercial land uses, which can allow people to walk to destinations such as stores.
"In future studies using GPS and activity monitors, we will try to move away from a focus on the area where people live to try to better understand the range of locations, near and far from home, where people are active and the characteristics of those environments," Troped said.
The research team fitted 148 people, ages 19-78, with activity monitors and GPS devices for four days - two weekdays and two weekend days - in the Boston metropolitan area. The activity monitors, also known as accelerometers, record the intensity of activity each minute during a person's waking hours. As the intensity for each minute increases, such as from walking to running, the activity count for each minute increases. If a person is sitting in a car or just fidgeting, then a low level of activity is reported. The global positioning systems device was worn whenever the individual was outdoors or leaving the home.
The findings were published in April's American Journal of Preventive Medicine.
"We are really just scratching the surface on this type of research, but it's a start," Troped said. "More work needs to be done to identify areas where people are physically active and better understand the qualities of those areas that attract people to them. We also need to learn how this might differ by age and racial and ethnic background so we can use this information to develop interventions for different audiences."
In addition to Troped, the research team was composed of Jeffrey S. Wilson of Indiana University-Purdue University Indianapolis: Charles E. Matthews of the National Cancer Institute: Ellen K. Cromley of the Institute for Community Research in Hartford, Conn.; and Steven J. Melly of the Harvard School of Public Health.
The study was supported with funding from the Active Living Research Program, The Robert Wood Johnson Foundation and Purdue's College of Liberal Arts.

University of Connecticut researchers have created a biodegradable composite made of silk fibers that can be used to repair broken load-bearing bones without the complications sometimes presented by other materials.
Repairing major load-bearing bones such as those in the leg can be a long and uncomfortable process.
Study published in the journal ACS Applied Materials & Interfaces is the outcome of an international effort that included teams from Dresden and Berlin in Germany, and the US.
Scientists at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) together with colleagues from the Helmholtz-Zentrum Berlin (HZB) and the University of Virginia...
Novel highly efficient and brilliant gamma-ray source: Based on model calculations, physicists of the Max PIanck Institute for Nuclear Physics in Heidelberg propose a novel method for an efficient high-brilliance gamma-ray source. A giant collimated gamma-ray pulse is generated from the interaction of a dense ultra-relativistic electron beam with a thin solid conductor. Energetic gamma-rays are copiously produced as the electron beam splits into filaments while propagating across the conductor. The resulting gamma-ray energy and flux enable novel experiments in nuclear and fundamental physics.
The typical wavelength of light interacting with an object of the microcosm scales with the size of this object. For atoms, this ranges from visible light to...
Stable joint cartilage can be produced from adult stem cells originating from bone marrow. This is made possible by inducing specific molecular processes occurring during embryonic cartilage formation, as researchers from the University and University Hospital of Basel report in the scientific journal PNAS.
Certain mesenchymal stem/stromal cells from the bone marrow of adults are considered extremely promising for skeletal tissue regeneration. These adult stem...
