GPS Watches for Measuring Energy Expenditure during Physical Activity
MetadataShow full item record
AbstractRecently, a number of global positioning system (GPS) devices have been introduced commercially which exploit GPS, transforming frequent measurements of time and location, into an estimate of energy expenditure. This fact sheet reviews how GPS watches (GPS fitness units) measure energy expenditure of individual during physical activity. We list popular GPS watches that are on the market and show pros and cons of these watches. After our field testing, we decided that the Garmin Forerunner 305 is our best pick for the GPS watch. We included information on geocaching, which is one of several popular outdoor activities using a GPS receiver or other navigational techniques.
